A bacterial isolate obtained from soil from a municipal landfill site in India was characterized using a polyphasic taxonomic approach. The colonies of the isolate were found to be yellow and highly mucoid. Comparative analysis of the 16S rRNA gene sequence showed that this isolate constitutes a distinct phyletic line within the genus Lysobacter, displaying >3 % sequence divergence with respect to recognized Lysobacter species. The generic assignment was confirmed by chemotaxonomic data, which revealed the presence of a fatty acid profile characteristic of members of the genus Lysobacter and consisting of saturated, unsaturated, straight-chain and branched-chain fatty acids as well as iso-C11 : 0 3-OH as hydroxylated fatty acid, and the presence of an ubiquinone with eight isoprene units (Q-8) as the predominant respiratory quinone. The genotypic and phenotypic data show that strain IMMIB APB-9T merits classification as representing a novel species of the genus Lysobacter, for which the name Lysobacter defluvii sp. nov. is proposed. The type strain is IMMIB APB-9T (=CCUG 53152T=DSM 18482T).

A yellow-pigmented, Gram-reaction-negative bacterium isolated from a human clinical source was investigated using a polyphasic approach in order to clarify its taxonomic status. Comparative 16S rRNA gene sequence analysis showed that the new isolate constituted a distinct phyletic line within the genus Chryseobacterium, displaying >2.8 % sequence divergence with recognized species of this genus. The generic assignment was confirmed by chemotaxonomic data which revealed a fatty acid profile consisting of straight-chain saturated, monounsaturated and branched-chain fatty acids of iso-/anteiso-types as well as 3-hydroxylated fatty acids; a menaquinone with six isoprene units (MK-6) as the predominant respiratory quinone and sym-homospermidine as the predominant polyamine. The novel isolate could be distinguished from other members of the genus Chryseobacterium by a set of distinct biochemical properties. On the basis of phenotypic and phylogenetic evidence, it is proposed that the new isolate represents a novel species of the genus Chryseobacterium for which the name Chryseobacterium treverense sp. nov. is proposed. The type strain is IMMIB L-1519T (=DSM 22251T=CCUG 57657T).

A bacterial strain, designated NSW-5T, was isolated from a water sample taken from Niao-Song Wetland Park in Taiwan and characterized using a polyphasic taxonomic approach. Cells of strain NSW-5T were strictly aerobic, Gram-stain-negative, non-motile and polymorphic, being straight, vibrioid, curved and spiral-shaped rods surrounded by a thick capsule and forming light pink-coloured colonies. Some rings consisting of several cells were present. Growth occurred at 10–40 °C (optimum, 25 °C), with 0–3.0 % NaCl (optimum, 0 %) and at pH 6.0–8.0 (optimum, pH 7.0). Phylogenetic analyses based on 16S rRNA gene sequences showed that strain NSW-5T belonged to the genus Arcicella with sequence similarities of 98.6, 98.0 and 97.3 % with Arcicella aquatica NO-502T, Arcicella rosea TW5T and Arcicella aurantiaca TNR-18T, respectively. The predominant cellular fatty acids were summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c; 20.8 %), C16 : 0 (14.6 %), iso-C15 : 0 (13.8 %), C16 : 1ω5c (12.5 %) and C18 : 0 (11.4 %), and the only respiratory quinone was MK-7. The polar lipid profile consisted of phosphatidylethanolamine and several uncharacterized glycolipids, aminolipids, phospholipids and aminophospholipids. The DNA G+C content of strain NSW-5T was 44.1 mol%. The DNA–DNA relatedness of strain NSW-5T with respect to recognized species of the genus Arcicella was less than 70 %. On the basis of phylogenetic inference and phenotypic data, strain NSW-5T should be classified as a representative of a novel species, for which the name Arcicella rigui sp. nov. is proposed. The type strain is NSW-5T ( = KCTC 23307T = BCRC 80260T). Emended descriptions of the genus Arcicella and of Arcicella aquatica , Arcicella rosea and Arcicella aurantiaca are also proposed.

Two yellow bacterial strains, designated NBD5T and NBD8, isolated from Noni (Morinda citrifolia L.) branch were investigated using a polyphasic taxonomic approach. Cells were Gram-stain-negative, aerobic, non-spore-forming, non-motile and short rod-shaped. Phylogenetic analysis based on 16S rRNA gene sequences suggested that the strains were members of a novel species of the genus Sphingomonas, the seven closest neighbours being Sphingomonas oligoaromativorans SY-6T (96.9  % similarity), Sphingomonas polyaromaticivorans B2-7T (95.8  %), Sphingomonas yantingensis 1007T (94.9  %), Sphingomonas sanguinis IFO 13937T (94.7  %), Sphingomonas ginsenosidimutans Gsoil 1429T (94.6  %), Sphingomonas wittichii RW1T (94.6  %) and Sphingomonas formosensis CC-Nfb-2T (94.5  %). Strains NBD5T and NBD8 had sphingoglycolipid, phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol and phosphatidylcholine as the major polar lipids, ubiquinone 10 as the predominant respiratory quinone, and sym-homospermidine as the major polyamine. Strains NBD5T and NBD8 were clearly distinguished from reference type strains based on phylogenetic analysis, DNA–DNA hybridization, fatty acid composition data analysis, and comparison of a range of physiological and biochemical characteristics. It is evident from the genotypic and phenotypic data that strains NBD5T and NBD8 represent a novel species of the genus Sphingomonas, for which the name Sphingomonas morindae sp. nov. is proposed. The type strain is NBD5T ( = DSM 29151T = KCTC 42183T = CICC 10879T).

A novel thermophilic, facultatively anaerobic bacterium, strain skLN1T, was isolated from the sediment of a freshwater lake in Japan. Cells of strain skLN1T were rod-shaped and Gram-stain-variable. A KOH lysis test suggested that the cell wall of the isolate has a Gram-positive structure. For aerobic growth, the optimum pH was pH 7.25–7.50 and the optimum temperature was 50–52 °C. The G+C content of the genomic DNA was 50.8 mol%. Nitrate was reduced to nitrite. Alicyclic fatty acids were not detected, and branched-chain fatty acids were major components in the cellular fatty acid profile. MK-7 was the predominant respiratory quinone. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the isolated strain was related most closely to Alicyclobacillus consociatus CCUG 53762T (95 % similarity). This analysis also showed that the monophyly of the genus Alicyclobacillus had been lost. On the basis of phylogenetic and phenotypic characterization, Effusibacillus lacus gen. nov., sp. nov. is proposed. The type strain of Effusibacillus lacus is skLN1T ( = NBRC 109614T = DSM 27172T). It is also proposed that Alicyclobacillus pohliae and Alicyclobacillus consociatus should be reclassified to the genus Effusibacillus as Effusibacillus pohliae comb. nov. and Effusibacillus consociatus comb. nov., respectively.
