sp. nov., isolated from human faeces Free

Abstract

A strictly anoxic, Gram-stain-positive, non-motile -like bacterium, designated strain M25, was isolated from a human faecal sample. Strain M25 was negative for both catalase and oxidase activity, utilized carbohydrates as fermentable substrates, produced lactate and acetate as the major end products of glucose fermentation in PYG medium, and had a DNA G+C content of 41.6 mol%. Comparative 16S rRNA gene sequencing showed that strain M25 was closely related to ATCC 29174 (96.40 % 16S rRNA gene sequence similarity) and HFTH-1 (96.17 %) within the family . Straight-chain saturated and monounsaturated cellular fatty acids were also detected, the majority being C, C and C dimethyl acetal acids. Based on the phenotypic, genotypic and phylogenetic characteristics presented in this study, strain M25 represents a novel species within the genus for which the name sp. nov. is proposed. The type strain is M25 ( = KCTC 5980 = JCM 17205).
