Abstract

Strains of a Gram-stain-negative, rod-shaped and immotile bacterium were isolated from broiler chicken caecal content. The isolates required strict anaerobic conditions for growth, formed spores, were catalase-positive and oxidase-negative. They produced butyrate as the major metabolic end product in reinforced clostridial medium broth. The genomic DNA G+C content of the isolated strains was 32.5–34.6 mol%. The major cellular fatty acids were C, C, C and C. The fatty acid composition of the cell wall showed no similarity to any strain in the database. 16S rRNA gene sequence analysis showed that the nearest phylogenetic neighbours were and (92 % sequence similarity) within cluster XIVa of the phylum . Therefore, a novel genus is proposed, with the name gen. nov., sp. nov. The type strain of is LMG 27730=DSM 26959.
