Abstract

Porcine pancreatic lipase (PPL) and Candida cylindracea lipase (CCL) were immobilized on Celite and Amberlite IRA 938 by deposition from the aqueous solution by the addition of hexane. The influence of the immobilization on the activities of the immobilized lipase derivatives has been studied. The immobilized lipases were used in synthesis of pentyl isovalerates. Various reaction parameters affecting the synthesis of pentyl isovalerates were investigated. The reaction rates were compared with the rates of esterification with free lipases. The immobilized lipases were found to be very effective in the esterification reaction. The lipases immobilized on Celite 545 exhibited better operational stabilities than that of immobilized on Amberlite IRA‐938.     

Morphological,biochemical and kinetic properties of lipase from Candida rugosa immobilized in zirconium phosphate

Zirconium phosphate (ZrP), a low-cost inorganic material with well-defined physicochemical properties, was successfully used as support for immobilizing Candida rugosa lipase by covalent bonding. The immobilized derivative showed high catalytic activity in both aqueous and non-aqueous media. Fourier transform infrared spectroscopy, X-ray diffraction, and scanning electron microscopy measurements demonstrated that the ZrP fulfilled the morphological requirements for use as a matrix for immobilizing lipases. The free and immobilized lipases were compared in terms of pH, temperature and thermal stability. The immobilized lipase had a higher pH optimum (7.5) and higher optimum temperature (50°C) than the free lipase. Immobilization also increased the thermal stability. The hydrolysis of p-nitrophenyl palmitate (pNPP) by immobilized lipase, examined at 37°C, followed Michaelis–Menten kinetics. Values for K_m=1.18 µM and V_max=325Umg^?1 indicated that the immobilized system was subject to mass transfer limitations. The immobilized derivative was also tested under repetitive reaction batches in both ester hydrolysis and synthesis.     

Immobilization and characterisation of a lipase from a new source, Bacillus sp. ITP-001

A new source of lipase from Bacillus sp. ITP-001 was immobilized by physical adsorption on the polymer poly(3-hydroxybutyrate-co-hydroxyvalerate) (PHBV) in aqueous solution. The support and immobilized lipase were characterised, compared to the lyophilised lipase, with regard to the specific surface area, adsorption–desorption isotherms, pore volume (Vp) and size (dp) by nitrogen adsorption, differential scanning calorimetry, thermogravimetric analysis, chemical composition analysis, Fourier transform infrared spectroscopy and biochemical properties. The immobilized enzyme displayed a shift in optimum pH towards the acidic side with an optimum at pH 4.0, whereas the optimum pH for the free enzyme was at pH 7.0; the optimum temperature of activity was 80 and 37 °C for the free and immobilized enzyme, respectively. The inactivation rate constant for the immobilized enzyme at 37 °C was 0.0038 h^?1 and the half-life was 182.41 h. The kinetic parameters obtained for the immobilized enzyme gave a Michaelis–Menten constant (K _m) of 49.10 mM and a maximum reaction velocity (V _max) of 205.03 U/g. Furthermore, the reuse of the lipase immobilized by adsorption allowed us to observe that it could be reused for 10 successive cycles, duration of each cycle (1 h), maintaining 33 % of the initial activity.     

Improving the activity and stability of Yarrowia lipolytica lipase Lip2 by immobilization on polyethyleneimine-coated polyurethane foam

In this study, polyurethane foam (PUF) was used for immobilization of Yarrowia lipolytica lipase Lip2 via polyethyleneimine (PEI) coating and glutaraldehyde (GA) coupling. The activity of immobilized lipases was found to depend upon the size of the PEI polymers and the way of GA treatment, with best results obtained for covalent-bind enzyme on glutaraldehyde activated PEI-PUF (MW 70,000 Da), which was 1.7 time greater activity compared to the same enzyme immobilized without PEI and GA. Kinetic analysis shows the hydrolytic activity of both free and immobilized lipases on triolein substrate can be described by Michaelis–Menten model. The K_m for the immobilized and free lipases on PEI-coated PUF was 58.9 and 9.73 mM, respectively. The V_max values of free and immobilized enzymes on PEI-coated PUF were calculated as 102 and 48.6 U/mg enzyme, respectively. Thermal stability for the immobilization preparations was enhanced compared with that for free preparations. At 50 °C, the free enzyme lost most of its initial activity after a 30 min of heat treatment, while the immobilized enzymes showed significant resistance to thermal inactivation (retaining about 70% of its initial activity). Finally, the immobilized lipase was used for the production of lauryl laurate in hexane medium. Lipase immobilization on the PEI support exhibited a significantly improved operational stability in esterification system. After re-use in 30 successive batches, a high ester yield (88%) was maintained. These results indicate that PEI, a polymeric bed, could not only bridge support and immobilized enzymes but also create a favorable micro-environment for lipase. This study provides a simple, efficient protocol for the immobilization of Y. lipolytica lipase Lip2 using PUF as a cheap and effective material.     

Immobilization of lipases on different carriers and their use in synthesis of pentyl isovalerates

Porcine pancreatic lipase (PPL) and Candida cylindracea lipase (CCL) were immobilized on Celite and Amberlite IRA 938 by deposition from the aqueous solution by the addition of hexane. The influence of the immobilization on the activities of the immobilized lipase derivatives has been studied. The immobilized lipases were used in synthesis of pentyl isovalerates. Various reaction parameters affecting the synthesis of pentyl isovalerates were investigated. The reaction rates were compared with the rates of esterification with free lipases. The immobilized lipases were found to be very effective in the esterification reaction. The lipases immobilized on Celite 545 exhibited better operational stabilities than that of immobilized on Amberlite IRA-938.     

Production of diacylglycerols from glycerol monooleate and ethyl oleate through free and immobilized lipase-catalyzed consecutive reactions

The ability of free and immobilized lipase on the production of diacylglycerols (DAG) by transesterification of glycerol monooleate (GMO) and ethyl oleate was investigated. Among three free lipases such as lipase G (Penicillium cyclopium), lipase AK (Pseudomonas fluorescens) and lipase PS (Pseudomonas cepacia), lipase PS exhibited the highest DAG productivity, and the DAG content gradually increased up to 24 hours reaction and then remained steady. The comparative result for DAG productivity between free lipase PS and immobilized lipases (lipase PS-D and Lipozyme RM IM) during nine times of 24 hours reaction indicated that total DAG production was higher in immobilized lipase PS-D (183.5mM) and Lipozyme RM IM (309.5mM) than free lipase PS (122.0mM) at the first reaction, and that the DAG production rate was reduced by consecutive reactions, in which more sn-1,3-DAG was synthesized than sn-1,2-DAG. During the consecutive reactions, the activity of lipase PS was relatively steady by showing similar DAG content, whereas DAG production of lipase PS-D and Lipozyme RM IM was gradually decreased to 69.9 and 167.1mM at 9th reaction, respectively, resulting in 62% and 46% reduced production when compared with 1st reaction. Interestingly, from 7th reaction lipase PS produced more DAG than immobilized lipase PS-D, and exhibited a stable activity for DAG production. Therefore, the present study suggested that DAG productivity between GMO and ethyl oleate was higher in immobilized lipases than free lipases, but the activity was reduced with repeated uses.     

Development of a monolith based immobilized lipase micro-reactor for biocatalytic reactions in a biphasic mobile system

This paper reports a simple method for producing macroporous silica-monoliths with controllable porosity that can be used for the immobilization of lipases to generate an active and stable micro-reactor for biocatalysis. A range of commercially available lipases has been examined using the hydrolysis reactions of 4-nitrophenyl butyrate in water–decane media. The kinetic studies performed have identified that a similar value for k_cat is obtained for the immobilized Candida antarctica lipase A (0.13 min⁻¹) and the free lipase in solution (0.12 min⁻¹) whilst the immobilized apparent Michaelis constant K_m (3.1 mM) is 12 times lower than the free lipase in solution (38 mM). A 96% conversion was obtained for the immobilized C. antarctica lipase A compared to only 23% conversion for the free lipase. The significant higher conversions obtained with the immobilized lipases were mainly attributed to the formation of a favourable biphasic system in the continuous flowing micro-reactor system, where a significant increase in the interfacial activation occurred. The immobilized C. antarctica lipase A on the monolith also exhibited improved stability, showing 64% conversion at 80 °C and 70% conversion after continuous running for 480 h, compared to 40 and 20% conversions under the same temperature and reaction time for the free lipase.     

Characterization of an organic solvent-tolerant lipase from Idiomarina sp. W33 and its application for biodiesel production using Jatropha oil

A halophilic strain W33 showing lipolytic activity was isolated from the saline soil of Yuncheng Salt Lake, China. Biochemical and physiological characterization along with 16S rRNA gene sequence analysis placed the isolate in the genus Idiomarina. The extracellular lipase was purified to homogeneity by 75 % ammonium sulphate precipitation, DEAE-Sepharose anion exchange and Sephacryl S-200 gel filtration chromatography. The molecular mass of the purified lipase was estimated to be 67 kDa by SDS-PAGE. Substrate specificity test indicated that it preferred long-chain p-nitrophenyl esters. Optimal lipase activity was found to be at 60 °C, pH 7.0–9.0 and 10 % NaCl, and it was highly active and stable over broad temperature (30–90 °C), pH (7.0–11.0) and NaCl concentration (0–25 %) ranges, showing excellent thermostable, alkali-stable and halotolerant properties. Significant inhibition by diethyl pyrocarbonate and phenylarsine oxide was observed, implying histidine and cysteine residues were essential for enzyme catalysis. In addition, the lipase displayed high stability and activity in the presence of hydrophobic organic solvents with log P _ow ≥ 2.13. The free and immobilized lipases produced by Idiomarina sp. W33 were applied for biodiesel production using Jatropha oil, and about 84 and 91 % of yields were achieved, respectively. This study formed the basic trials conducted to test the feasibility of using lipases from halophile for biodiesel production.     

Characterization of an organic solvent-tolerant lipase from Haloarcula sp. G41 and its application for biodiesel production

A haloarchaeal strain G41 showing lipolytic activity was isolated from the saline soil of Yuncheng Salt Lake, China. Biochemical and physiological characterizations along with 16S rRNA gene sequence analysis placed the isolate in the genus Haloarcula. Lipase production was strongly influenced by the salinity of growth medium with maximum in the presence of 20 % NaCl or 15 % Na₂SO₄. The lipase was purified to homogeneity with a molecular mass of 45 kDa. Substrate specificity test revealed that it preferred long-chain p-nitrophenyl esters. The lipase was highly active and stable over broad ranges of temperature (30–80 °C), pH (6.0–11.0), and NaCl concentration (10–25 %), with an optimum at 70 °C, pH 8.0, and 15 % NaCl, showing thermostable, alkali-stable, and halostable properties. Enzyme inhibition studies indicated that the lipase was a metalloenzyme, with serine and cysteine residues essential for enzyme function. Moreover, it displayed high stability and activation in the presence of hydrophobic organic solvents with log P _ow?≥?2.73. The free and immobilized lipases from strain G41 were applied for biodiesel production, and 80.5 and 89.2 % of yields were achieved, respectively. This study demonstrated the feasibility of using lipases from halophilic archaea for biodiesel production.     

Immobilized CALB Catalyzed Transesterification of Soybean Oil and Phytosterol

Candida antarctica lipase B (CALB) was immobilized on Fe₃O₄/SiO_x-g-P(GMA) polymer carrier to catalyzed the transesterification of soybean oil and phytosterol. The enzyme loading of the obtained particles was 98.7 mg/g supports and the enzyme activity was 1226.5 U/g. The average particle size was 100.5?±?1.30 nm and the magnetization was 15.80 emu/g. The immobilized enzyme showed higher activities at a wider range of pH and temperatures. Its optimum reaction temperature was up to 50 °C; increased by 5 °C compared to the free enzyme. The obtained magnetic immobilized Fe₃O₄/SiO_x-g-P(GMA) lipase was nanoscale. First-grade soybean oils were used as a substrate. System pH was adjusted to 7.0. The optimal reaction temperature was 50 °C and the reaction time was 3 h. The phytosterol concentration of 5% and immobilized CALB of 2% were obtained. The conversion rate of transesterification reaction between soybean oil and phytosterol was 86.2%. The use of magnets can quickly separate the immobilized enzymes from the substrates. The relative activity of the immobilized enzymes was 83.0% when reused seven times. The prepared immobilized CALB can improve efficiently enzyme activity and reutilization.     

Partial characterization of a crude cold-active lipase from Rhodococcus cercidiphylli BZ22

Cold-active lipase production by the psychrophilic strain Rhodococcus cercidiphylli BZ22 isolated from hydrocarbon-contaminated alpine soil was investigated. Depending on the medium composition, high cell densities were observed at a temperature range of 1–10 °C in Luria–Bertani (LB) broth or 1–30 °C in Reasoner’s 2A (R2A). Maximum enzyme production was achieved at a cultivation temperature of 1–10 °C in LB medium. About 70–80 % of the secreted enzyme was bound to the cell and was highly active as a cell-immobilized lipase which exhibited good reusability; more than 60 % of the initial lipase activity was retained after five-fold reuse. The properties of the lipase produced by the investigated strain were compared with those of a mesophilic porcine pancreatic lipase (PPL). The thermal stability of the cell-immobilized bacterial lipase was higher than that of the extracellular enzyme. Highest activity was detected at 30 °C for the cell-immobilized enzyme and for PPL, while the extracellular enzyme displayed highest activity at 10–20 °C. The bacterial lipase hydrolyzed p-nitrophenyl (p-NP) esters with different acyl chain lengths (C₂–C₁₈). The highest hydrolytic activity was obtained with p-NP-butyrate (C₄) as substrate, while the highest substrate affinity was obtained with p-NP-dodecanoate (C₁₂) as substrate, indicating a clear preference of the enzyme for medium acyl chain lengths.     

A novel thermostable lipase from Basidiomycete <Emphasis Type="Italic">Bjerkandera adusta </Emphasis>R59: characterisation and esterification studies

Microbial lipases are widely diversified in their enzymatic properties and substrate specificities, which make them very attractive for industrial application. Partially purified lipase from Bjerkandera adusta R59 was immobilized on controlled porous glass (CPG) and its properties were compared with those of the free enzyme. The free and immobilized lipases showed optimal activities at 45 and 50°C, respectively. Both enzyme forms were highly thermostable up to 60°C. The enzymes were stable at pH from 6.0 to 9.0 and their optimal pH for activity was 7.0. The free lipase was more thermostable in n-hexane than in aqueous environment. Both lipase preparations had good stabilities in non-polar solvents and were capable of hydrolysing a variety of synthetic and natural fats. Non-immobilized lipase activity was inhibited by disulphide bond reagents, serine and thiol inhibitors, while EDTA and eserine had no effect on enzyme activity. All anionic detergents tested in experiments inhibited lipase activity. The free lipase showed good stability in the presence of commercial detergents at laundry pH and temperatures. Applications of free and immobilized lipases for esterification were also presented.     

Enhanced Reactivity of Rhizopus oryzae Lipase Displayed on Yeast Cell Surfaces in Organic Solvents: Potential as a Whole-Cell Biocatalyst in Organic Solvents

Immobilization of enzymes on some solid supports has been used to stabilize enzymes in organic solvents. In this study, we evaluated applications of genetically immobilized Rhizopus oryzae lipase displayed on the cell surface of Saccharomyces cerevisiae in organic solvents and measured the catalytic activity of the displayed enzyme as a fusion protein with α-agglutinin. Compared to the activity of a commercial preparation of this lipase, the activity of the new preparation was 4.4 × 10⁴-fold higher in a hydrolysis reaction using p-nitrophenyl palmitate and 3.8 × 10⁴-fold higher in an esterification reaction with palmitic acid and n-pentanol (0.2% H₂O). Increased enzyme activity may occur because the lipase displayed on the yeast cell surface is stabilized by the cell wall. We used a combination of error-prone PCR and cell surface display to increase lipase activity. Of 7,000 colonies in a library of mutated lipases, 13 formed a clear halo on plates containing 0.2% methyl palmitate. In organic solvents, the catalytic activity of 5/13 mutants was three- to sixfold higher than that of the original construct. Thus, yeast cells displaying the lipase can be used in organic solvents, and the lipase activity may be increased by a combination of protein engineering and display techniques. Thus, this immobilized lipase, which is more easily prepared and has higher activity than commercially available free and immobilized lipases, may be a practical alternative for the production of esters derived from fatty acids.     

Characterization of the lipase immobilized on Mg–Al hydrotalcite for biodiesel

Immobilization of Saccharomyces cerevisiae lipase by physical adsorption on Mg–Al hydrotalcite with a Mg/Al molar ratio of 4.0 led to a markedly improved performance of the enzyme. The immobilized lipase retained activity over wider ranges of temperature and pH than those of the free lipase. The immobilized lipase retained more than 95% relative activity at 50 °C, while the free lipase retained about 88%. The kinetic constants of the immobilized and free lipases were also determined. The apparent activation energies (E_a) of the free and immobilized lipases were estimated to be 6.96 and 2.42 kJ mol^?1, while the apparent inactivation energies (E_d) of free and immobilized lipases were 6.51 and 6.27 kJ mol^?1, respectively. So the stability of the immobilized lipase was higher than that of free lipase. The water content of the oil must be kept below 2.0 wt% and free fatty acid content of the oil must be kept below 3.5 mg KOH g [oil]^?1 in order to get the best conversion. This immobilization method was found to be satisfactory to produce a stable and functioning biocatalyst which could maintain high reactivity for repeating 10 batches with ester conversion above 81.3%.     

Sustainable preparation of a novel glycerol-free biofuel by using pig pancreatic lipase: Partial 1,3-regiospecific alcoholysis of sunflower oil

The preparation of a novel biofuel denoted as Ecodiesel-100 from the partial 1,3-regiospecific alcoholysis of sunflower oil is reported. Pig pancreatic lipase (PPL) was employed in the reaction as both free and immobilised enzyme on sepiolite. The resulting biofuel is composed of fatty acid ethyl esters and monoglycerides (FAEE/MG) blended in a molar relation 2/1. The novel biofuel has similar physico-chemical properties compared to those of conventional biodiesel and/or petrodiesel, avoiding the production of glycerine as by-product.The biocatalyst was found to be strongly fixed to the inorganic support (87.5%). Nevertheless, the efficiency of the immobilised enzyme was reduced to less than half (42%) compared to that of the free PPL. Quantitative conversions of triglycerides and high yields to FAEE were obtained under mild reaction conditions (20–80 °C, oil/alcohol 2/1 v:v ratio and PPL 0.01–0.1% w/w of total substrate). The immobilised enzyme showed a remarkable stability as well as a great reusability (more than 11 successive reuses) without a significant loss of its initial catalytic activity. Both immobilised and free enzyme exhibited the same reaction mechanism, according to the coincidental results in the Arrhenius parameters (Ln A and E_a). The immobilised PPL was found to be very suitable for the continuous production of biofuel due to its facile recyclability from the reaction mixture.     

Investigation of deactivation thermodynamics of lipase immobilized on polymeric carrier

In the present work, we have investigated biochemical thermo-kinetic stability of lipases immobilized on a biocompatible polymeric material. Immobilization of lipase Candida rugosa (CRL) was carried out on biocompatible blend of poly vinyl alcohol (PVA) and chitosan (CHY) support via entrapment and glutardehyde (Glu) cross-linking method to produce PVA:CHY:CRL and PVA:CHY:Glu:CRL as robust biocatalyst. These immobilized lipases were characterized by various physico-biochemical characterization techniques. Later on, thermal and solvent stability of polymer immobilized lipase was determined in term of half-life time (t _0.5), D values, enthalpy (ΔH°), entropy (ΔS°), and free energy (ΔG°) of deactivation at different temperatures and in various solvents. The thermodynamic deactivation stability trend was found as: cross-linked lipase CRL > entrapped lipase CRL > free lipase CRL. Moreover, kinetic parameters, such as K _m, V _max, and catalytic efficiency, were also determined to understand the kinetic features. The polymer immobilized enzyme was reused to investigate the economic viability of the developed biocatalyst.

     

Immobilization of lipase in organic solvent in the presence of fatty acid additives

In this study porcine pancreatic lipase (PPL) was covalently immobilized on cross-linked polyvinyl alcohol (PVA) in organic media in the presence of fatty acid additives in order to improve its immobilized activity. The effects of fatty acid additions to the immobilization media were investigated choosing tributyrin hydrolysis in water and ester synthesis by immobilized PPL in n-hexane. Various fatty acids which are also the substrates of lipases in esterification reactions were used as active site protecting agents during the immobilization process in an organic solvent. The obtained results showed that covalent immobilization carried out in the presence of fatty acids as protective ligands improved the hydrolytic and esterification activity of immobilized enzyme. A remarkable increase in activity of the immobilized PPL was obtained when octanoic acid was used as an additive and the hydrolytic activity was increased from 5.2 to 19.2 μmol min⁻¹ mg⁻¹ as compared to the non-additive immobilization method. With the increase of hydrolytic activity of immobilized lipase in the presence of octanoic acid, in an analogous manner, the rate of esterification for the synthesis of butyl octanoate was also increased from 7.3 to 26.3 μmol min⁻¹ g⁻¹ immobilized protein using controlled thermodynamic water activities with saturated salt solutions. In addition, the immobilized PPL activity was maintained at levels representing 63% of its original activity value after 5 repeated uses. The proposed method could be adopted for a wide variety of other enzymes which have highly soluble substrates in organic solvent such as other lipases and esterases.     

Immobilization and Characterization of a Thermostable Lipase

Lipases have found a number of commercial applications. However, thermostable lipase immobilized on nanoparticle is not extensively characterized. In this study, a recombinant thermostable lipase (designated as TtL) from Thermus thermophilus WL was expressed in Escherichia coli and immobilized onto 3-APTES-modified Fe₃O₄@SiO₂ supermagnetic nanoparticles. Based on analyses with tricine–sodium dodecyl sulfate–polyacrylamide gel electrophoresis, X-ray diffraction, transmission electron microscopy, and vibrating sample magnetometer observation, the diameter of immobilized lipase nanoparticle was 18.4 (±2.4)?nm, and its saturation magnetization value was 52.3 emu/g. The immobilized lipase could be separated from the reaction medium rapidly and easily in a magnetic field. The biochemical characterizations revealed that, comparing with the free one, the immobilized lipase exhibited better resistance to temperature, pH, metal ions, enzyme inhibitors, and detergents. The K _m value for the immobilized TtL (2.56 mg/mL) was found to be lower than that of the free one (3.74 mg/mL), showing that the immobilization improved the affinity of lipase for its substrate. In addition, the immobilized TtL exhibited good reusability. It retained more than 79.5 % of its initial activity after reusing for 10 cycles. Therefore, our study presented that the possibility of the efficient reuse of the thermostable lipase immobilized on supermagnetic nanoparticles made it attractive from the viewpoint of practical application.     

Functional expression of a novel alkaline-adapted lipase of Bacillus amyloliquefaciens from stinky tofu brine and development of immobilized enzyme for biodiesel production

Using enrichment procedures, a lipolytic strain was isolated from a stinky tofu brine and was identified as Bacillus amyloliquefaciens (named B. amyloliquefaciens Nsic-8) by morphological, physiological, biochemical tests and 16S rDNA sequence analysis. Meanwhile, the key enzyme gene (named lip _BA) involved in ester metabolism was obtained from Nsic-8 with the assistance of homology analysis. The novel gene has an open reading frame of 645 bp, and encodes a 214-amino-acid lipase (Lip_BA). The deduced amino acid sequence shows the highest identity with the lipase from B. amyloliquefaciens IT-45 (NCBI database) and belongs to the family of triacylglycerol lipase (EC 3.1.1.3). The lipase gene was expressed in Escherichia coli BL21(DE3) using plasmid pET-28a. The enzyme activity and specific activity were 250 ± 16 U/ml and 1750 ± 153 U/mg, respectively. The optimum pH and temperature of the recombinant enzyme were 9.0 and 40 °C respectively. Lip_BA showed much higher stability under alkaline conditions and was stable at pH 7.0–11.0. The Km and Vmax values of purified Lip_BA using 4-nitrophenyl palmitate as the substrate were 1.04 ± 0.06 mM and 119.05 ± 7.16 μmol/(ml min), respectively. After purification, recombinant lipase was immobilized with the optimal conditions (immobilization time 3 h at 30 °C, with 92 % enzyme recovery) and the immobilized enzyme was applied in biodiesel production. This is the first report of the lipase activity and lipase gene obtained from B. amyloliquefaciens (including wild strain and recombinant strain) and the recombinant Lip_BA with the detailed enzymatic properties. Also the preliminary study of the transesterification shows the potential value in biodiesel production applications.     

Improvement of catalytic activity of Candida rugosa lipase in the presence of calix[4]arene bearing iminodicarboxylic/phosphonic acid complexes modified iron oxide nanoparticles

In the present study, iron oxide magnetite nanoparticles, prepared through a co-precipitation method, were coated with phosphonic acid or iminodicarboxylic acid derivatives of calix[4]arene to modulate their surfaces with different acidic groups. Candida rugosa lipase was then directly immobilized onto the modified nanoparticles through sol–gel encapsulation. The catalytic activities and enantioselectivities of the two encapsulated lipases in the hydrolysis reaction of (R/S)-naproxen methyl ester and (R/S)-2-phenoxypropionic acid methyl ester were assessed. The results showed that the activity and enantioselectivity of the lipase were improved when the lipase was encapsulated in the presence of calixarene-based additives; the encapsulated lipase with the phosphonic acid derivative of calix[4]arene had an excellent rate of enantioselectivity against the (R/S)-naproxen methyl and (R/S)-2-phenoxypropionic acid methyl esters, with E = 350 and 246, respectively, compared to the free enzyme. The encapsulated lipases (Fe-Calix-N(COOH)) and (Fe-Calix–P) showed good loading ability and little loss of enzyme activity, and the stability of the catalyst was very good; they only lost 6–11% of the enzyme’s activity after five batches.
