Strain YCS-16^T was found to contain MK-6 as the predominant menaquinone and iso-C_17:0 3-OH, iso-C_15:1 G and iso-C_15:0 as the major fatty acids. The major polar lipids detected in strain YCS-16^T were phosphatidylethanolamine and one unidentified lipid. The DNA G+C content of strain YCS-16^T was determined to be 35.7 mol%. The phylogenetic analysis, chemotaxonomic data and other phenotypic properties revealed that strain YCS-16^T constitutes a new genus and species within the family Flavobacteriaceae, for which the name Geojedonia litorea gen. nov., sp. nov. is proposed. The type strain of Geojedonia litorea is YCS-16^T (=KCTC 32260^T = CCUG 63682^T).     

<Emphasis Type="Italic">Algoriella xinjiangensis</Emphasis> gen. nov., sp. nov., a new psychrotolerant bacterium of the family <Emphasis Type="Italic">Flavobacteriaceae</Emphasis>

An aerobic, Gram-stain negative, non-spore-forming and psychrotolerant bacterium, designated strain XJ109^T, was isolated from a sewage water sample collected from Xinjiang Uigur Autonomous Region, China. Phylogenetic analysis based on 16S rRNA gene sequence indicated that strain XJ109^T represents a novel member of the family Flavobacteriaceae. The strain showed 95.5 % similarity with the 16S rRNA gene sequence of Empedobacter brevis LMG 4011^T, 95.4 % with Chishuiella changwenlii BY4^T, 95.3 % with Empedobacter falsenii NF 993^T and 92.3 % with Weeksella virosa DSM 16922^T. Strain XJ109^T showed the common phenotypic and chemotaxonomic characteristics of the family Flavobacteriaceae, containing menaquinone-6 (MK-6) as the predominant respiratory quinone and iso-C_17:0 3OH and iso-C_15:0 as the major fatty acids. The polar lipid profile consisted of phosphatidylethanolamine, one unidentified phospholipid and two unidentified lipids. The genomic DNA G+C content was 38.0 mol%. Strain XJ109^T was positive for catalase and oxidase activities, and it was observed to grow at 4–30 °C (optimal 16–20 °C), pH 6.5–10.0 (optimal 7.0–7.5) and in media containing 0–2.0 % (w/v) NaCl (optimal 0.5 %). On the basis of the polyphasic evidence presented, strain XJ109^T is considered to represent a novel genus and species of the family Flavobacteriaceae, for which the name Algoriella xinjiangensis gen. nov., sp. nov. is proposed. The type strain is XJ109^T (=CGMCC 1.10229^T=JCM 16590^T).     

Gordonibacter faecihominis sp. nov., isolated from human faeces

A novel actinobacterial strain, designated CAT-2^T, was isolated from human faeces as a bacterium capable of dehydroxylating (+)-catechin derivatives. Strain CAT-2^T was found to be strictly anaerobic, Gram-positive, non-motile and non-spore-forming coccobacilli. The major fatty acids were identified as C_16:0 DMA (dimethy acetal), C_16:0, C_14:0, anteiso-C_15:0 and iso-C_14:0. The three predominant menaquinones were identified as MK-6 (menaquinene-6), MMK-6 (monomethylmenaquinone-6) and DMMK-6 (dimethylmenaquinone-6). The polar lipids were found to be diphosphatidylglycerol, phosphatidylglycerol and four unidentified glycolipid. The DNA G+C content of strain CAT-2^T was 68.4 mol%. Phylogenetic analysis based on 16S rRNA gene sequence similarities showed that strain CAT-2^T belongs to the genus Gordonibacter, sharing the highest level of sequence homology with Gordonibacter pamelaeae DSM 19378^T (97.3 %). Combined phenotypic, chemotaxonomic and phylogenetic characteristics support the conclusion that the strain CAT-2^T represents a novel species, for which the name Gordonibacter faecihominis sp. nov. is proposed. The type strain is CAT-2^T (= KCTC 15204^T = JCM 16058^T).
