sp. nov., isolated from cow faeces.

A Gram-stain-negative, non-spore-forming, yellow-pigmented, aerobic, pleomorphic rod-shaped bacterium, designated ZY171143, was isolated from faeces of a cow with diarrhoea in Wenshan, Yunnan Province, south-west China and its taxonomic position was studied. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain ZY171143 belonged to the family and was most closely related to the only species of the genus , CCTCC AB 2016016 with a sequence similarity of 97.8 %. The genomic OrthoANI and digital DNA-DNA hybridization values between the strain and CCTCC AB 2016016 were 86.2 and 30.5 %, respectively. The genomic G+C content was 31.1 mol%. The predominant fatty acids (>5 %) were C iso, C iso 3OH, C, Cω5 and summed feature 3 (Cω7 and/or 16 : 1 ω6c). The major polar lipids were phosphatidylethanolamine, triacylglycerol and sulfonolipid. The sole respiratory quinone was MK-6. These chemotaxonomic characterizations also revealed that strain ZY171143 was a member of the genus . Based on the phenotypic, chemotaxonomic and genotypic data, strain ZY171143 represents a novel species within the genus , for which the name sp. nov. is proposed. The type strain is ZY171143 (=CGMCC 1.13663=KCTC 62642).
