title: Gordonibacter faecihominis sp. nov., isolated from human faeces.
abstract: 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 C16:0 DMA (dimethy acetal), C16:0, C14:0, anteiso-C15:0 and iso-C14:0. 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)).
