An obligately anaerobic, Gram-stain-positive and coccus-shaped bacterium, designated strain YH-panp20 T , was isolated from pig faeces. Phylogenetic analysis based on 16S rRNA gene sequencing indicated that the isolate belongs to the family Erysipelotrichaceae , and is most closely related to Catenisphaera adipataccumulans KCTC 15517 T (93.5 % sequence similarity), followed by Faecalitalea cylindroides KCTC 5815 T (92.2 %), Faecalicoccus acidiformans KCTC 15521 T (90.2 %) and Holdemanella biformis KCTC 5969 T (89.6 %). Average nucleotide identity values between YH-panp20 T and its closest relatives were lower than 71 %. The G+C content of the isolate was 38.4 mol%, and its cell-wall peptidoglycan was found to be of A1γ type and contained meso -diaminopimelic acid. The predominant fatty acids were C 18 : 1 cis 9, C 18 : 0 DMA and C 16 : 0 . The major end-products of glucose fermentation were lactate, acetate and formate. Therefore, based on the phenotypic, phylogenetic and chemotaxonomic properties, a novel genus and species, Absicoccus porci gen. nov., sp. nov., is proposed for isolate YH-panp20 T (=KCTC 15747 T =JCM 32769 T ).
