Lachnobacterium bovis gen. nov., sp nov., a novel bacterium isolated from the rumen and faeces of cattle

Phenotypic and phylogenetic analysis was performed on four strains of a pre viously undescribed Gram-positive, rod-shaped, anaerobic bacterium isolated from the rumen and faeces of cattle. This bacterium fermented glucose prim arily to lactic acid along with minor amounts of acetic and butyric acids. The four strains produced a temperature-sensitive bacteriocin-like inhibito ry substance. Comparative 16S rRNA gene sequence analysis indicated that th e bacterium was a member of the clostridial XIVa cluster of the low-G+C con tent Gram-positive bacteria. Based on phylogenetic and phenotypic evidence, it is proposed that the unknown bacterium be assigned to a new genus, Lach nobacterium, as Lachnobacterium bovis gen. nov., sp. nov. The type strain i s YZ 87(T) (= ATCC BAA-151(T) = DSM 14045(T) = LRC 5382(T)). Its G+C conten t is 33.9 mol%.
