Two mesophilic anaerobic bacterial strains (Z7T and Z1) were isolated from waste water sludge of the Xinanzhang paper mill, Beijing, China. The strains were Gram-positive, non-spore-forming and motile. Cells were thin rods (0·2–0·4×4·0–8·0 μm). Growth of the strains was observed at 20–42 °C and pH 5·0–7·5. Both strains hydrolysed gelatin and aesculin and fermented several kinds of mono-, di- and oligosaccharides. The fermentation end products formed from glucose were acetate, ethanol, hydrogen and carbon dioxide. The predominant cellular fatty acids were the branched-chain fatty acids isoC15 : 0 (42·83 %) and isoC14 : 0 (32·11 %). The DNA G+C contents of strains Z7T and Z1 were 50·4 and 48·6 mol%, respectively. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the isolates represent a new phyletic sublineage within the Clostridium leptum rRNA cluster, with <91 % 16S rRNA gene sequence similarity to currently described species. On the basis of polyphasic evidence from this study, Acetanaerobacterium elongatum gen. nov., sp. nov., a novel genus and species, is proposed, with strain Z7T (=JCM 12359T=AS 1.5012T) as the type strain.

Three Gram-negative, motile, mesophilic, aerobic, rod-shaped bacterial strains, designated 2O1T, 1O14 and 1O18, were isolated from Indonesian seawater after enrichment with crude oil and a continuous supply of supplemented seawater. The strains exhibited high n-alkane-degrading activity, which indicated that the strains were important degraders of petroleum aliphatic hydrocarbons in tropical marine environments. Phylogenetic analyses based on 16S rRNA gene sequences of members of the Gammaproteobacteria showed that the isolates formed a coherent and distinct cluster in a stable lineage containing Oceanobacter kriegii IFO 15467T (96.4–96.5 % 16S rRNA gene sequence similarity) and Thalassolituus oleivorans MIL-1T. DNA G +C content was 53.0–53.1 mol%. The major fatty acids were C16 : 0, C16 : 1 ω7 and C18 : 1 ω9 and the hydroxy fatty acids were C12 : 0 3-OH and C10 : 0 3-OH. The polar lipids were phosphatidylglycerol, a ninhydrin-positive phospholipid(s) and glycolipids. The major quinone was Q-9 (97–99 %), which distinguished the isolates from Oceanobacter kriegii NBRC 15467T (Q-8; 91 %). On the basis of phenotypic, genotypic and chemotaxonomic data, including DNA–DNA hybridization, the isolates represent a novel genus and species, for which the name Oleibacter marinus gen. nov., sp. nov. is proposed. The type strain of Oleibacter marinus is 2O1T (=NBRC 105760T =BTCC B-675T).

Two mesophilic, anaerobic bacterial strains (ZLJ115T and L4-2) were isolated from the sludge of an anaerobic digester treating municipal solid waste and sewage in Fujian province, China. The strains were Gram-positive, spore-forming, motile rods (0·9–1·0×3·6–7·3 μm). Growth of the strains was observed at 20–42 °C and pH 6·0–9·5. Both strains fermented several mono- and disaccharides. The main fermentation products from glucose were acetate, ethanol, hydrogen and carbon dioxide. Optimal hydrogen production by the new isolates was observed at pH 8·8 and 39 °C, and 1·4 mol H2 was detected from fermentation of 1 mol glucose. The DNA G+C contents of strains ZLJ115T and L4-2 were 53·9 and 54·3 mol%, respectively. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the isolates represented a novel phyletic sublineage within cluster XI of the clostridia, clustering with four thermophilic species, with <93·8 % 16S rRNA gene sequence similarity to previously described species. Phenotypically, the new isolates were distinguished from their phylogenetic relatives by growing mesophilically and by fermenting a variety of pentoses, as well as their higher genome DNA G+C content. On the basis of polyphasic evidence from this study, a novel genus and species are proposed, Sporacetigenium mesophilum gen. nov., sp. nov.; strain ZLJ115T (=DSM 16796T=AS 1.5019T) is the type strain of Sporacetigenium mesophilum.

Two strictly anaerobic bacterial strains (YUAN-3T and X-29) were isolated from anaerobic activated sludge of molasses wastewater in a continuous stirred-tank reactor. The strains were Gram-positive, non-spore-forming, mesophilic and motile. Cells were regular rods (0·4–0·8×1·5–8·0 μm) and occurred singly, in pairs and sometimes in chains of up to eight. Autoaggregative and autofluorescent growth of strain YUAN-3T and non-aggregative growth of strain X-29 were observed at 20–44 °C and pH 3·5–9·0. Both strains hydrolysed gelatin and aesculin and fermented several kinds of mono-, di- and oligosaccharides. Fermentation end products formed from glucose were acetate, ethanol, hydrogen and carbon dioxide. The predominant cellular fatty acids were the branched-chain fatty acids iso-C16 : 0 (44·18 %) and iso-C12 : 0 (26·67 %). The DNA G+C contents of strains YUAN-3T and X-29 were 47·8 and 49·0 mol%, respectively. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the isolates represent a novel phyletic sublineage within the Clostridium cellulosi rRNA cluster, with <92 % 16S rRNA gene sequence similarity to currently known species. On the basis of polyphasic evidence from this study, it is proposed that the unknown bacterium should be classified in a new genus as a novel species, Ethanoligenens harbinense gen. nov., sp. nov. The type strain of Ethanoligenens harbinense is YUAN-3T (=JCM 12961T=CGMCC 1.5033T).

An actinobacterial strain containing demethylmenaquinone DMK-9(H4) as the diagnostic isoprenoid quinone was isolated from a tidal flat sediment sample, from South Korea. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain JC2054T represents a distinct phyletic line within the suborder Micrococcineae of the order Actinomycetales. The closest phylogenetic neighbour was Cellulomonas fermentans, with 94.7 % 16S rRNA gene sequence similarity. The novel isolate was strictly aerobic and slightly halophilic, with optimum growth occurring in 2–4 % (w/v) NaCl. Cells were non-motile, non-sporulating and rod-shaped. The peptidoglycan type was of the A-type of cross-linkage. l-ornithine was the diamino acid and d-glutamate represented the N-terminus of the interpeptide bridge. The predominant fatty acids were anteiso-branched and straight-chain fatty acids. The major polar lipids were phosphatidylinositol, diphosphatidylglycerol and an unknown phospholipid. The menaquinone composition of C. fermentans was determined to be MK-10(H4), MK-9(H4) and MK-8(H4) in the ratio 56 : 2 : 1. On the basis of the polyphasic evidence presented in this study, it is proposed that strain JC2054T should be classified as representing a novel genus and species of the suborder Micrococcineae, with the name Demequina aestuarii gen. nov., sp. nov. The type strain is JC2054T (=IMSNU 14027T=KCTC 9919T=JCM 12123T). In addition, it was clear from the phylogenetic analysis and chemotaxonomic data that C. fermentans does not belong to the genus Cellulomonas or any other recognized genera. Therefore, C. fermentans should be reclassified as representing a novel genus, for which the name Actinotalea fermentans gen. nov., comb. nov. is proposed, with strain DSM 3133T (=ATCC 43279T=CFBP 4259T=CIP 103003T=NBRC 15517T=JCM 9966T=LMG 16154T) as the type strain.

Thirteen bacterial isolates from lake sediment, capable of degrading cyanobacterial hepatotoxins microcystins and nodularin, were characterized by phenotypic, genetic and genomic approaches. Cells of these isolates were Gram-negative, motile by means of a single polar flagellum, oxidase-positive, weakly catalase-positive and rod-shaped. According to phenotypic characteristics (carbon utilization, fatty acid and enzyme activity profiles), the G+C content of the genomic DNA (66·1–68·0 mol%) and 16S rRNA gene sequence analysis (98·9–100 % similarity) the strains formed a single microdiverse genospecies that was most closely related to Roseateles depolymerans (95·7–96·3 % 16S rRNA gene sequence similarity). The isolates assimilated only a few carbon sources. Of the 96 carbon sources tested, Tween 40 was the only one used by all strains. The strains were able to mineralize phosphorus from organic compounds, and they had strong leucine arylamidase and chymotrypsin activities. The cellular fatty acids identified from all strains were C16 : 0 (9·8–19 %) and C17 : 1 ω7c (<1–5·8 %). The other predominant fatty acids comprised three groups: summed feature 3 (<1–2·2 %), which included C14 : 0 3-OH and C16 : 1 iso I, summed feature 4 (54–62 %), which included C16 : 1 ω7c and C15 : 0 iso OH, and summed feature 7 (8·5–28 %), which included ω7c, ω9c and ω12t forms of C18 : 1. A more detailed analysis of two strains indicated that C16 : 1 ω7c was the main fatty acid. The phylogenetic and phenotypic features separating our strains from recognized bacteria support the creation of a novel genus and species, for which the name Paucibacter toxinivorans gen. nov., sp. nov. is proposed. The type strain is 2C20T (=DSM 16998T=HAMBI 2767T=VYH 193597T).

Protaetia Brevitarsis Seulensis

Taxonomic positions of four Gram-negative bacterial strains, which were isolated from larvae of two insects in Jeju, Republic of Korea, were determined by a polyphasic approach. Strains CWB-B4, CWB-B41 and CWB-B43 were recovered from larvae of Protaetia brevitarsis seulensis, whereas strain BWR-B9T was from larvae of Allomyrina dichotoma. All the isolates grew at 10–37 °C, at pH 5.0–9.0 and in the presence of 4 % (w/v) NaCl. The 16S rRNA gene phylogeny showed that the four isolates formed two distinct sublines within the order Enterobacteriales and closely associated with members of the genus Jinshanibacter . The first group represented by strain CWB-B4 formed a tight cluster with Jinshanibacter xujianqingii CF-1111T (99.3 % sequence similarity), whereas strain BWR-B9T was most closely related to Jinshanibacter zhutongyuii CF-458T (99.5 % sequence similarity). The 92 core gene analysis showed that the isolates belonged to the family Budviciaceae and supported the clustering shown in 16S rRNA gene phylogeny. The genomic DNA G+C content of the isolates was 45.2 mol%. A combination of overall genomic relatedness and phenotypic distinctness supported that three isolates from Protaetia brevitarsis seulensis are different strains of Jinshanibacter xujianqingii , whereas one isolate from Allomyrina dichotoma represents a new species of the genus Jinshanibacter . On the basis of results obtained here, Jinshanibacter allomyrinae sp. nov. (type strain BWR-B9T=KACC 22153T=NBRC 114879T) and Insectihabitans xujianqingii gen. nov., comb. nov. are proposed, with the emended descriptions of the genera Jinshanibacter , Limnobaculum and Pragia .

Four Gram-negative, orange-coloured, aerobic, heterotrophic bacteria were isolated from sediment samples collected on the Pacific coast of Japan near the cities of Toyohashi and Katsuura. 16S rRNA gene sequence analysis indicated that these strains form a distinct lineage within the family Flavobacteriaceae. The four isolates shared 99.9–100 % 16S rRNA gene sequence similarity with each other and showed 88–90.9 % similarity with their neighbours in the family Flavobacteriaceae. The four strains also shared high DNA–DNA reassociation values of 67–99 % with each other. All the strains grew at 37 °C but not at 4 °C, and degraded gelatin, starch and DNA. The major fatty acids were i-C15 : 0, a-C15 : 0, i-C16 : 0 and i-C17 : 0 3-OH. However, two common fatty acids of members of the Flavobacteriaceae, i-C15 : 1 and a-C15 : 1, were absent in these strains. The DNA G+C contents of the four strains were in the range 35–37 mol%. On the basis of the polyphasic evidence, it was concluded that these strains should be classified as a novel genus and a novel species in the family Flavobacteriaceae, for which the name Sandarakinotalea sediminis gen. nov., sp. nov. is proposed. The type strain of Sandarakinotalea sediminis is CKA-5T (=NBRC 100970T=LMG 23247T).

A water sample from the North Sea was used to isolate the abundant heterotrophic bacteria that are able to grow on complex marine media. Isolation was by serial dilution and spread plating. Phylogenetic analysis of nearly complete 16S rRNA gene sequences revealed that one of the strains, HEL-45T, had 97·4 % sequence similarity to Sulfitobacter mediterraneus and 96·5 % sequence similarity to Staleya guttiformis. Strain HEL-45T is a Gram-negative, non-motile rod and obligate aerobe and requires sodium and 1–7 % sea salts for growth. It contains storage granules and does not produce bacteriochlorophyll. Optimal growth temperatures are 25–30 °C. The DNA base composition (G+C content) is 60·1 mol%. Strain HEL-45T has Q10 as the dominant respiratory quinone. The major polar lipids are phosphatidyl glycerol, diphosphatidyl glycerol, phosphatidyl choline, phosphatidyl ethanolamine and an aminolipid. The fatty acids comprise 18 : 1ω7c, 18 : 0, 16 : 1ω7c, 16 : 0, 3-OH 10 : 0, 3-OH 12 : 1 (or 3-oxo 12 : 0) and traces of an 18 : 2 fatty acid. Among the hydroxylated fatty acids only 3-OH 12 : 1 (or 3-oxo 12 : 0) appears to be amide linked, whereas 3-OH 10 : 0 appears to be ester linked. The minor fatty acid components (between 1 and 7 %) allow three subgroups to be distinguished in the Sulfitobacter/Staleya clade, placing HEL-45T into a separate lineage characterized by the presence of 3-OH 12 : 1 (or 3-oxo 12 : 0) and both ester- and amide-linked 16 : 1ω7c phospholipids. HEL-45T produces indole and derivatives thereof, several cyclic dipeptides and thryptanthrin. Phylogenetic analysis of 16S rRNA gene sequences and chemotaxonomic data support the description of a new genus and species, to include Oceanibulbus indolifex gen. nov., sp. nov., with the type strain HEL-45T (=DSM 14862T=NCIMB 13983T).

Two Gram-negative, non-motile, pleomorphic bacterial strains, DS-40T and DS-45T, were isolated from a soil sample collected from Dokdo, Korea, and their exact taxonomic positions were investigated by using a polyphasic approach. Strains DS-40T and DS-45T grew optimally at 25 °C and pH 6.5–7.5 in the presence of 0–1.0 % (w/v) NaCl. They contained MK-7 as the predominant menaquinone and possessed iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 3 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH) as the major fatty acids. The DNA G+C contents of strains DS-40T and DS-45T were 36.0 and 36.8 mol%, respectively. Strains DS-40T and DS-45T shared a 16S rRNA gene sequence similarity of 96.7 % and demonstrated a mean DNA–DNA relatedness level of 12 %. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strains DS-40T and DS-45T were most closely phylogenetically affiliated with the genus Pedobacter of the family Sphingobacteriaceae. Strains DS-40T and DS-45T exhibited 16S rRNA gene sequence similarity values of 91.4–93.7 and 89.9–91.6 % with respect to the type strains of Pedobacter and Sphingobacterium species, respectively. Phenotypic and chemotaxonomic properties, together with the phylogenetic data, support the assignment of strains DS-40T and DS-45T as two distinct species within the genus Pedobacter. On the basis of phenotypic, phylogenetic and genetic data, strains DS-40T and DS-45T represent two novel species of the genus Pedobacter, for which the names Pedobacter lentus sp. nov. and Pedobacter terricola sp. nov. are proposed, respectively. The respective type strains are DS-40T (=KCTC 12875T=JCM 14593T) and DS-45T (=KCTC 12876T=JCM 14594T).

Two bacterial strains (JC247T and JC248) were isolated from soil samples collected from Rann of Kutch, Gujarat, India. Colonies of both strains were creamy white. Cells were Gram-stain-positive, rods-to-curved rods (crescent-shaped), and produced centrally located oval-shaped endospores. Major (>5 %) fatty acids of both strains were iso-C16  :  0, iso-C14  :  0, iso-C15  :  0, C16  :  1ω11c and C16  :  0, with minor ( < 5 but >1 %) amounts of anteiso-C15  :  0, anteiso-C17  :  0, iso-C16  :  1 H, iso-C17  :  0, iso-C18  :  0, C14  :  0, C17  :  0, C18  :  0, C18  :  1ω9c, iso-C17  :  1ω10c and anteiso-C17  :  0B/isoI. Diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol were the major polar lipids of both strains. Cell-wall amino acids were l-alanine, d-alanine, d-glutamic acid and meso-diaminopimelic acid. The genomic DNA G+C content of strains JC247T and JC248 was 48.2 and 48.1 mol%, respectively. Both strains were closely related with mean DNA–DNA hybridization >90 %. 16S rRNA gene sequence analysis of both strains indicated that they are members of the genus Bacillus within the family Bacillaceae of the phylum Firmicutes. Both strains had a 16S rRNA gene sequence similarity of 96.93 % with Bacillus firmus NCIMB 9366T and < 96.92 % with other members of the genus Bacillus. Sequence similarity between strain JC247T and JC248 was 100 %. Distinct morphological, physiological and genotypic differences from previously described taxa support the classification of strains JC247T and JC248 as representatives of a novel species of the genus Bacillus, for which the name Bacillus crescens sp. nov. is proposed. The type strain is JC247T ( = KCTC 33627T = LMG 28608T).
