Two types of new anaerobic bacteria were isolated from anoxic freshwater sediments. They grew in mineral medium with oxalate as sole energy source and with acetate as main carbon source. Oxalate as well as oxamate (after deamination) were decarboxylated to formate with growth yields of 1.2–1.4 g dry cell matter per mol oxalate degraded. No other organic or inorganic substrates were used, and no electron acceptors were reduced. Strain WoOx3 was a Gramnegative, non-sporeforming, motile vibrioid rod with a guanine-plus-cytosine content of the DNA of 51.6 mol%. It resembled the previously described genus Oxalobacter, and is described as a new species, O. vibrioformis. Strain AltOx1 was a Gram-positive, spore-forming, motile rod with a DNA base ratio of 36.3 mol% guanine-plus-cytosine. This isolate is described as a new species of the genus Clostridium, C. oxalicum.  相似文献

A new mesophilic, sporeforming, strictly anaerboic bacterium was isolated form enrichments with 2,3-butanediol as sole substrate and pasteurized freshwater sediment as inoculum. Cells were large, motile rods, and elliptical spores were formed subterminally or centrally. They stained Gram-negative, but no typical outer membrane layer could be observed by electron microscopy of ultrathin sections. 2,3-Butanediol, acetoin, fructose, glucose, sucrose, xylose, malate and citrate served as substrates and were completely converted to acetate with concomitant reduction of carbon dioxide. Growth on glucose (t dmin=1.4 h) was faster than on butanediol (t dmin=3.6 h). No growth occurred on hydrogen/carbon dioxide, on formate or on methanol. The guanine plus cytosine content of the DNA was 29.1%. The new isolate is described as a new species, Clostridium magnum sp. nov.  相似文献

Strain T2–7, a 5-aminovalerate-fermenting bacterium previously classified as Clostridium aminovalericum, was further characterized, both physiologically and phylogenetically. Comparative sequencing analysis of the almost complete 16S rDNA revealed that strain T2–7 forms a distinct lineage within a phylogenetically coherent cluster of gram-positive bacteria currently assigned to the genus Clostridium. Strain T2–7 grew with 5-aminovalerate, 5-hydroxyvalerate, 4-hydroxybutyrate, vinylacetate, and crotonate, and required yeast extract and l-cysteine for growth. Other substrates were not utilized. The fermentation products, depending on the growth substrate, were ammonia, acetate, propionate, butyrate, and valerate. Sulphur was reduced by a mechanism not linked to energy conservation. Other acceptors were not utilized. Cells were gram-positive pointed-ended ovals, motile by means of two subpolar flagella, and possessed a gram-positive cell wall structure with an S-layer of hexagonally arranged subunits of 18.5 nm diameter. The DNA mol% G+C was 41.5. Strain T2–7 (DSM 6836) is proposed as the type strain of a new species, Clostridium viride sp. nov. Dedicated to H. A. Barker on the occasion of his 87th birthday  相似文献

A thermophilic, rod-shaped, motile, Gram-positive, spore-forming bacterium strain 70BT was isolated from a geothermally active underground mine in Japan. The temperature and pH range for growth was 50–81°C (optimum 71°C) and 6.2–9.8 (optimum pH 7–7.5), respectively. Growth occurred in the presence 0–2% NaCl (optimum 1% NaCl). Strain 70BT could utilize glucose, fructose, mannose, mannitol, pyruvate, cellobiose and tryptone as substrates. Thiosulfate was used as electron acceptor. Major whole-cell fatty acids were iso-C15:0, C16:0 DMA (dimethyl acetal), C16:0 and anteiso-C15:0. The G+C mol% of the DNA was 44.2%. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that the closest relatives of strain 70BT were Thermosediminibacter oceani DSM 16646T (94% similarity) and Thermosediminibacter litoriperuensis DSM 16647 (93% similarity). The phenotypic, chemotaxonomic and phylogenetic properties suggest that strain 70BT represents a novel species in a new genus, for which the name Thermovorax subterraneus gen. nov., sp. nov. is proposed. The type strain of Thermovorax subterraneus is 70BT (=DSM 21563 = JCM 15541).  相似文献

From anoxic marine sediment samples, new anaerobic, microaerotolerant, Gram-negative, non-sporeforming bacteria were isolated which grew in mineral medium with malonate as sole source of carbon and energy. Cells were motile thin rods, often forming large aggregates. Malonate was decarboxylated to acetate with concomitant growth yields of 1.9–2.1 g dry cell matter per mol malonate degraded. Fumarate and malate were fermented to succinate and CO2. No other substrates were used. No inorganic electron acceptors were reduced. At least 150 mM NaCl was required for growth with either substrate. High amounts of a periplasmic cytochrome c were detected, as well as small amounts of a membrane-bound cytochrome b. All enzymes of the citric acid cycle were found to be present. The DNA base ratio was 48.3 mol% guanine plus cytosine. Since this new bacterium cannot be affiliated with any of the known genera and species, a new genus and species, Malonomonas rubra is proposed.  相似文献

A new genus of marine methanogenic bacteria and two species within this genus are described.Methanogenium is the proposed genus andMethanogenium cariaci the type species. Cells of the type species are Gram-negative, peritrichously flagellated, irregular cocci with a periodic wall surface pattern. Colonies formed by these bacteria are yellow, circular and umbonate with entire edges. The DNA base composition is 52 mol% guanine plus cytosine. Formate or hydrogen and carbon dioxide serve as substrates for growth. Cells ofMethanogenium marisnigri are of similar shape but smaller diameter thanM. cariaci. The colonies ofM. marisnigri are convex, and the DNA base composition is 61 mol % G+C. Formate or hydrogen and carbon dioxide are growth substrates. Sodium chloride is required for growth of both methanogens.Abbreviations SDS sodium dodecylsulfate - PIPES piperazine-N,N-bis (2 ethanesulfonic acid) - HS-CoM coenzyme M, 2-mercaptoethanesulfonic acid  相似文献

Anaerobic bacteria degrading 2-methoxyethanol were enriched from freshwater sediments, and three strains were isolated in pure culture. Two of them were Grampositive non-spore-forming rods and grew strictly anaerobically by acetogenic fermentation. Optimal growth occurred at 30°C, initial pH 7.5–8.0. 2-Methoxyethanol and 2-ethoxyethanol were fermented to acetate and corresponding alcohols. Hydrogen plus carbon dioxide, formate, acetoin, l-malate, lactate, pyruvate, fructose, and methoxyl groups of 3,4,5-trimethoxybenzoate and 3,4,5-trimethoxycinnamate were fermented to acetate. 1,2-Propanediol was fermented to acetate, propionate, and propanol. Strain MuME1 was described as a new species, Actetobacterium malicum. It had a DNA base composition of 44.1 mol% guanine plus cytosine. The third strain, which was identified as Pelobacter venetianus, fermented 2-methoxyethanol to methanol, ethanol, and acetate.  相似文献

Enrichments on succinate plus yeast extract under anoxic conditions from intertidal mud-flat sediments yielded cultures dominated by oval to round-ended rod-shaped cells. Strain 10succ1, obtained in pure culture, was characterized in detail. The non-motile cells possessed a gram-negative cell wall and did not form spores. Carbohydrates were fermented to formate, acetate, ethanol, and lactate. Succinate was decarboxylated to propionate. Other organic and amino acids were variously fermented to formate, acetate, propionate, and butyrate. Sulfur, sulfate, thiosulfate, and nitrate were not used as electron acceptors. Growth required the presence of yeast extract and at least 5 g/l NaCl, and was possible only in the absence of oxygen. No cytochromes were detected. The DNA base ratio was 40 mol% G+C. Phylogenetically, strain 10succ1 is closely related to Propionigenium modestum, as revealed by 16S rDNA analysis, but is physiologically distinct. Accordingly, strain 10succ1 (DSM 9537) is described as the type strain of a new species of the genus Propionigenium, P. maris sp. nov. Received: 12 January 1995 / Accepted: 24 February 1995  相似文献

An anaerobic phthalate isomer-degrading strain (JTT) that we previously isolated was characterized. In addition, a strictly anaerobic, mesophilic, syntrophic phthalate isomer-degrading bacterium, designated strain JIT, was isolated and characterized in this study. Both were non-motile rods that formed spores. In both strains, the optimal growth was observed at temperatures around 37°C and neutral pH. In syntrophic co-culture with the hydrogenotrophic methanogen Methanospirillum hungatei, both strains could utilize two or three phthalate isomers for growth, and produce acetate and methane as end products. Strain JTT was able to grow on isophthalate, terephthalate, and a number of low-molecular weight aromatic compounds, such as benzoate, hydroquinone, 2-hydroxybenzoate, 3-hydroxybenzoate, 2,5-dihydroxybenzoate, 3-phenylpropionate in co-culture with M. hungatei. It could also grow on crotonate, hydroquinone and 2,5-dihydroxybenzoate in pure culture. Strain JIT utilized all of the three phthalate isomers as well as benzoate and 3-hydroxybenzoate for growth in co-culture with M. hungatei. No substrates were, however, found to support the axenic growth of strain JIT. Neither strain JTT nor strain JIT could utilize sulfate, sulfite, thiosulfate, nitrate, fumarate, Fe (III) or 4-hydroxybenzoate as electron acceptor. Phylogenetically, strains JTT and JIT were relatively close to the members of the genera Pelotomaculum and Cryptanaerobacter in ‘Desulfotomaculum lineage I’. Physiological and chemotaxonomic characteristics indicated that the two isolates should be classified into the genus Pelotomaculum, creating two novel species for them. Here, we propose Pelotomaculum terephthalicum sp. nov. and Pelotomaculum isophthalicum sp. nov. for strain JTT and strain JIT, respectively. The type strains are strains JTT (= DSM 16121T = JCM 11824T = NBRC 100523T) and JIT (= JCM 12282T = BAA-1053T) for P. terephthalicum and P. isophthalicum, respectively.Nucleotide sequence accession number: The GenBank/EMBL/DDBJ accession numbers of the 16S rRNA gene sequences of strains JTT and JIT are AB091323 and AB232785, respectively  相似文献

A novel Gram-negative, slightly halophilic, catalase- and oxidase-positive, obligately aerobic bacterium, strain YIM-C248T, was isolated from a sediment sample collected from a salt-lake in the Qaidam Basin in Qinghai, north-west China. Cells were non-sporulating short rods, occurring singly or as doublets, motile with peritrichous flagella. Growth occurred with 1–15% (w/v) NaCl [optimum 2–4% (w/v) NaCl], at pH 6.0–10.0 (optimum pH 7.5) and at 4–35°C (optimum 25–30°C). The major cellular fatty acids were C18:1 ω7c, C12:0 3-OH, cyclo C19:0 ω8c, C16:0 and C16:1. The predominant respiratory quinone was Q-9 and the genomic DNA G + C content was 58.6 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain YIM-C248T should be assigned to the genus Halomonas. The sequence similarities between the isolate and the type strains of members of the genus Halomonas were in the range of 92.5–97.5%. The combination of phylogenetic analysis, DNA–DNA hybridization data, phenotypic characteristics and chemotaxonomic differences supported the view that strain YIM-C248T represents a new species of the genus Halomonas, for which the name Halomonas sediminis sp. nov. is proposed, with YIM-C248T (=CCTCC AA 207031 = KCTC 22167) as the type strain. The GenBank/EMBL/DBBJ accession number for the 16S rRNA gene sequence of strain YIM-C248T is EU135707.  相似文献

The name Rhodospirillum salexigens, spec. nov., was proposed for the strain WS 68, isolated by W. R. Sistrom at the Oregon coast from salt water. The spiral-shaped phototrophically or chemotrophically growing, salt demanding bacterium contains intracytoplasmic membranes arranged parallel to the cytoplasmic membrane. Bacteriochlorophyll a and spirilloxanthin are the major pigments. Growth occurs between 20 and 45°C at a neutral pH. The DNA base composition was 64 mol % guanine plus cytosine. The cell wall contains peptidoglycan and proteins but no glycolipids.  相似文献

Desulfovibrio strain JJ isolated from estuarine sediment differed from all other described Desulfovibrio species by the ability to degrade fructose. The oxidation was incomplete, leading to acetate production. Fructose, malate and fumarate were fermented mainly to succinate and acetate in the absence of an external electron acceptor. The pH and temperature optima for growth were 7.0 and 35° C respectively. Strain JJ was motile by means of a single polar flagellum. The DNA base composition was 64.13% G+C. Cytochrome c 3 and desulfoviridin were present. These characteristics established the isolate as a new species of the genus Desulfovibrio, and the name Desulfovibrio fructosovorans is proposed.  相似文献

Two related novel alkaliphilic and slightly halophilic bacteria are described. They are strain N10 from Lake Chahannor in China and strain 1E1 from Lake Elmenteita in East Africa. Both strains are strictly aerobic, heterotrophic, alkaliphilic, mesophilic, and require NaCl for growth. The optimal conditions for growth were at pH 10–10.5 and 2–3% (w/v) NaCl. Cells of both strains were Gram-negative, rod-shaped, non-spore-forming, and motile with a single polar flagellum. Cellular fatty acids in both strains were predominantly saturated and mono-unsaturated straight-chain fatty acids (16:0, 16:17c and 18:17c). The major isoprenoid quinone of both strains was Q8. The major polar lipids are phosphatidylglycerol, diphosphatidylglycerol, phosphatidylglycerol phosphate and phosphatidylethanolamine. The guanine plus cytosine (G+C) content of the DNA was 52.5 mol% and 55.4 mol%, respectively. Phylogenetic analysis revealed that the two strains formed a distinct lineage within the gamma-3 subclass of the Proteobacteria. The strains shared a 16S rDNA sequence similarity of 96.1% and showed less than 93.7% of sequence similarity to any other known species. Based on polyphasic data, the two strains were differentiated from currently recognized genera and represent a new genus, Alkalimonas gen. nov., with two species, Alkalimonas amylolytica sp. nov. (type strain is N10T = AS 1.3430) and Alkalimonas delamerensis sp. nov. ( type strain is 1E1P, T = CBS 391.94). The GenBank accession numbers for the 16S rRNA gene sequence of strains N10 and 1E1 are AF250323 and X92130, respectively.Communicated by K. Horikoshi  相似文献

Two extremely halophilic archaeal strains GX3(T) and GX26(T) were isolated from the Gangxi marine solar saltern near the Weihai city of Shandong Province, China. Cells from the two strains were pleomorphic and stained Gram-negative, colonies were red-pigmented. Strains GX3(T) and GX26(T) were able to grow at 25-50 °C (optimum 37 °C), at 1.4-5.1M NaCl (optimum 3.1M), at pH 5.5-9.5 (optimum pH 7.0) and neither strain required Mg(2+) for growth. Cells lyse in distilled water and the minimal NaCl concentration to prevent cell-lysis was 8% (w/v). The major polar lipids of the two strains were PA (phosphatidic acid), PG (phosphatidylglycerol), PGP-Me (phosphatidylglycerol phosphate methyl ester) and three major glycolipids (GL1, GL2 & GL3) chromatographically identical to S-TGD-1 (sulfated galactosyl mannosy glucosyl diether), S-DGD-1 (sulfated mannosyl glucosyl diether), and DGD-1 (mannosyl glucosyl diether) respectively, an unidentified lipid (GL4) was also detected in strain GX26(T). Phylogenetic analysis based on 16S rRNA gene revealed that strain GX3(T) and strain GX26(T) formed a distinct clade with the closest relative, Haladaptatus paucihalophilus (89.9-92.4% and 90.4-92.7, respectively). The rpoB' gene similarities between strains GX3(T) and GX26(T), and between the two strains and the closest relative, Halorussus rarus TBN4(T) are 96.5%, 84.3% and 83.9%, respectively. The DNA G+C contents of strain GX3(T) and strain GX26(T) are 67.3 mol% and 67.2 mol%, respectively. The DNA-DNA hybridization value between strain GX3(T) and strain GX26(T) was 44%. The phenotypic, chemotaxonomic and phylogenetic properties suggest that strain GX3(T) and strain GX26(T) represent two novel species in a new genus within the family Halobacteriaceae, Halorubellus salinus gen. nov., sp. nov. (type strain GX3(T)=CGMCC 1.10384(T)=JCM 17115(T)) and Halorubellus litoreus sp. nov. (type strain GX26(T)=CGMCC 1.10386(T)=JCM 17117(T)).  相似文献

A bacterial strain, designated Iso4T, was isolated from the East Sea of Korea and was subjected to a poly-phasic taxonomy study including phenotypic and chemotaxonomic characteristics as well as 16S rRNA gene sequence analysis. Cells of the strain were Gram-negative, motile, non-budding, non-stalked, and strictly aerobic. Strain Iso4T grew optimally at 20°C in the presence of 1∼2% (w/v) NaCl and at pH 6.9∼7.6. The major respiratory quinone was Q-10 and the major cellular fatty acids were C18:1 ω7c (53.5%), C17:1 ω5c (11.7%), C17:1 ω6c (8.1%), C16:0 (7.8%), C17:0 (4.8%), C15:0 (2.9%), and C16:1 ω5c (2.2%). The DNA G+C content of strain Iso4T was 56.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain Iso4T formed a monophyletic clade in the family Hyphomonadaceae, supported by high bootstrap value and was most closely related to the genus Hyphomonas (92∼94%), a member of marine bacteria in the family. The phenotypic, genotypic, and chemotaxonomic evidences also suggest strain Iso4T represents a novel genus and species in the family Hyphomonadaceae, for which the name Henriciella gen. nov., sp. nov. is proposed. The type strain is Iso4T (=KCTC 12513T =DSM 19595T =JCM 15116T).  相似文献

A new purple sulfur bacterium was isolated in pure culture (strain 8315) from a laminated microbial mat at Great Sippewissett Salt Marsh, Cape Cod, Mass., USA. Single cells were large rods, 10–20 times longer than wide, and predominantly strainght with slightly conical ends. Cells were motile by polarly inserted flagellar tufts. Intracellular photosynthetic membranes were of the vesicular-type. Photosynthetic pigments were bacteriochlorophylla and the carotenoids lycopene, rhodovibrin, anhydrorhodovibrin, and rhodopin. The new bacterium was strictly anaerobic and obligately phototrophic. Hydrogen, hydrogen sulfide, elemental sulfur, and thiosulfate were used as electron donors for photoautotrophic growth. In sulfide-reduced, bicarbonate-containing media, acetate, propionate, and pyruvate were photoassimilated. Growth factors were not required. Optimum growth rates were obtained at pH 7.3, 30°C, a salinity of 1.5–5.0% NaCl, and a light intensity of about 500 lx (tungsten lamp). The DNA base composition of strain 8315 was 60.4 mol% G+C. Comparison of 16S rDNA oligonucleotide catalogue data showed that the new bacterium must be considered a new genus of the Chromatiaceae. The nameRhabdochromatium is revived, and the new speciesRhabdochromatium marinum sp. nov. is described.  相似文献

A new genus of strictly anaerobic, gram-negative, banana-shaped bacteria is described. Cells formed spores and were motile by means of up to 15 laterally inserted flagella. Nitrate or sulfate were not used as electron acceptor. Organic substrates that were fermented included N-methyl compounds, such as betaine, N,N-dimethylglycine and sarcosine, primary alcohols, hydroxy fatty acids, and 2,3-butanediol. In addition, molecular hydrogen and carbon dioxide were fermented to acetate. The latter was the characteristic fermentation product in general. During growth on betaine, trimethylamine was formed in addition. The degradation of N,N-dimethylglycine yielded acetate, monomethylamine, and trimethylamine. The presence of cytochrome b and of ubiquinone in the cells was shown. The deoxyribonuleic acid base composition of the strains was between 41.3 and 47.4 mol% guanine plus cytosine. The name Sporomusa is proposed for this new genus. On the basis of the DNA-DNA homology values obtained, the shape of the spores and some other properties, the isolated strains were assigned to two species. Names proposed: Sporomusa sphaeroides and Sporomusa ovata. The type species is S. sphaeroides and the type strains are strain E, DSM 2875 (S. sphaeroides) and strain H1, DSM 2662 (S. ovata).Dedicated to Prof. H. G.

A Gram-positive, motile, endospore-forming and rod-shaped halophilic bacterial strain MSS-155 (KCTC 3788 and KCCM 41687) was isolated from a marine solar saltern of the Yellow Sea in Korea and was subjected to a polyphasic taxonomic study. This organism grew at temperature of 10.0–42.0°C with an optimum of 35°C. Strain MSS-155 grew optimally in the presence of 10% NaCl and did not grow in the absence of NaCl. The cell wall peptidoglycan type of strain MSS-155 was A4 based on l-Orn-d-Asp. Strain MSS-155 was also characterized chemotaxonomically by having menaquinone-7 (MK-7) as the predominant isoprenoid quinone and anteiso-C15:0 as the major fatty acid. The DNA G+C content was 44.0 mol%. Phylogenetic analysis based on 16S rDNA sequences showed that strain MSS-155 falls within the radiation of the cluster comprising Halobacillus species. Levels of 16S rDNA sequence similarity between strain MSS-155 and the type strains of four Halobacillus species were in the range 97.6–98.8%. Strain MSS-155 exhibited levels of DNA-DNA relatedness of 6.2–11.2% to the type strains of Halobacillus species described previously. On the basis of phenotypic properties, phylogeny, and genomic data, strain MSS-155 should be placed in the genus Halobacillus as a member of a novel species, for which we propose the name Halobacillus locisalis sp. nov.Communicated by W.D.

In a taxonomic study on the ascomycetous yeasts isolated from plant materials collected in tropical forests in Yunnan and Hainan Provinces, southern China, four strains isolated from tree sap (YJ2E(T)) and flowers (YF9E(T), YWZH3C(T) and YYF2A(T)) were revealed to represent four undescribed yeast species. Molecular phylogenetic analysis based on the large subunit (26S) rRNA gene D1/D2 domain sequences showed that strain YJ2E(T) was located in a clade together with Candida haemulonii and C. pseudohaemulonii. Strain YF9E(T) was most closely related to C. azyma and strain YWZH3C(T) to C. sorbophila and C. spandovensis. Strain YYF2A(T) was clustered in a clade containing small-spored Metschnikowia species and related anamorphic Candida species. The new strains differed from their closely related described species by more than 10% mismatches in the D1/D2 domain. No sexual states were observed for the four strains on various sporulation media. The new species are therefore assigned to the genus Candida and described as Candida alocasiicola sp. nov. (type strain, YF9E(T) = AS 2.3484(T) = CBS 10702(T)), Candida hainanensis sp. nov. (type strain, YYF2A(T) = AS 2.3478(T) = CBS 10696(T)), Candida heveicola sp. nov. (type strain, YJ2E(T) = AS 2.3483(T) = CBS 10701(T)) and Candida musiphila sp. nov. (type strain, YWZH3C(T) = AS 2.3479(T) = CBS 10697(T)).  相似文献

A motile, Gram-positive, slightly halophilic, endospore-forming, catalase- and oxidase-positive, obligately aerobic, slender rod-shaped bacterium, strain YIM-C229T was isolated from the sediment of a salt lake in the Qaidam Basin, north-west China. Filamentous forms were present throughout the growth cycle. Strain YIM-C229T grew in the presence of 0.5-8% NaCl and at pH 6.0-8.5, with optimum growth at 1-3% NaCl and pH 7.0-7.5. It grew at 4-45 degrees C, with optimum growth at 37 degrees C. The major cellular fatty acids were anteiso-C15:0, C16:0, iso-C15:0, C16:1 omega11c and anteiso-C(17:0). The predominant respiratory quinone was MK-7, and diphosphatidylglycerol and phosphatidylglycerol were the polar lipids, with meso-diaminopimelic acid occurring in the cell-wall peptidoglycan. The genomic DNA G+C content was 40.9 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YIM-C229T was closely related to the type strains of the four recognized species of the genus Gracilibacillus: G. halotolerans NN T (sequence similarity 95.5%), G. dipsosauri DD1T (96.1%), G. orientalis XH-63T (96.8%) and G. boraciitolerans T-16X(T) (99.1%). The DNA-DNA relatedness between strain YIM-C229(T) and G. boraciitolerans DSM 17256(T) was 30.8%. The combination of phylogenetic analysis, phenotypic characteristics, chemotaxonomic differences and DNA-DNA hybridization data supported the view that this strain represented a novel species of the genus Gracilibacillus, for which the name Gracilibacillus quinghaiensis sp. nov. is proposed, with YIM-C229T (=DSM 17858T=CGMCC 1.6304T) as the type strain.  相似文献
