Defatted cashew nut shell starch as renewable polymeric material: Isolation and characterization

Starch attracts public attention as a replacement of fossil fuel in polymer industries because it is renewable, biodegradable and nontoxic. In this study, the isolation of starch from defatted cashew nut shell (CNS) using wet milling was reported. A product that contains 85.01 wt.% starch was recovered from the defatted CNS. Various analyses were performed on the starch to characterize its physicochemical properties. It was found that the starch obtained possesses high amylopectin content (75.35 wt.%), which supports the results of thermal analysis that proved the high crystallinity of starch. Morphological study of the starch showed that bonded resins were found attached to the starch granules. Due to high crystallinity, the presence of bonded resins and low cost, starch from defatted CNS can be considered as a prospective renewable material in polymer industries, with potential to compete with current feedstock such as potato and corn.

Recycling potential and selective retrieval of Bacillus sphaericus from soil in a mosquito habitat

A selective medium containing a combination of starch, milk proteins, and streptomycin was used as a reliable indicator for the presence of Bacillus sphaericus in soil samples collected from a mosquito habitat where this pathogen was previously applied. The medium can also be used as an indicator substrate to retrieve B. sphaericus from infected mosquito larvae. Results show that B. sphaericus remains viable and infective 9 months after application as a larvacidal agent of mosquitoes in a roadside ditch.

In vitro propagation of Anacardium occidentale L.

Multiple buds have been induced from cotyledonary nodes of cashew, Anacardium occidentale L. Maximum number of buds were initiated on Murashige & Skoog's (MS) medium supplemented with 117 mM sucrose, 14.6 mM maltose and 22.2 M BA. The buds were harvested at each subculture after elongation on MS medium supplemented with 100 ml l^-1 coconut water, 14.6 mM maltose, increased sucrose (146 mM) and decreased BA (4.4 M). Excised microshoots were rooted in vitro on MS medium in the presence of 117 mM sucrose, 2.9 M IAA and 4.9 M IBA. Plantlets have been successfully transferred to soil and have been established in the field.     

In Vitro Root Formation in Anacardium Occidentale Microshoots

Cultural conditions affecting the induction of rhizogenesis in vitro were evaluated in cashew (Anacardium occidentale L.) shoot-node-derived microshoots. The application of auxins was essential for the formation of adventitious roots. A 5-d indole-3-butyric acid (IBA) induction period was more suitable than continuous IBA treatment or a shorter induction period. N⁶-[2-Isopentenyl]adenine in low concentrations (0.3 – 1 µM) in the root induction medium supported root formation. Precultivation of microshoots with gibberellic acid (GA₃) suppressed the subsequent rhizogenesis. Activated charcoal did not affect rooting. No significant differences in rooting abilities of cashew shoots were observed between 25, 29 and 35 °C and roots did not develop at 19 °C. Salts of low osmotic composition were more suitable than richer media. Microshoots originated from cotyledonary nodes showed higher rooting when compared to standard microshoots.     

Evaluation of Antimicrobial Activity of Cashew Tree Gum

Crude and purified cashew tree gum were tested for their antimicrobial activity against bacteria, yeast and fungi. Their use was also evaluated as a carbon source for microbial growth. Cashew gum presented only a weak activity against Saccharomyces cerevisiae and no activity was observed against all other microorganisms tested. The possibility that removal of anacardic acid present in the raw gum during purification may explain the negative results obtained was discussed. When purified cashew tree gum was used as carbon source, only Listeria monocytogenes, Saccharomyces cerevisiae and Kluyveromyces marxianus did not grow after 5 days of incubation.
