Abstract

Four butyrate-producing isolates were obtained from the caecal content of a 4-week-old broiler chicken. The 16S rRNA gene sequences were determined and confirmed the close relatedness of the four isolates, which suggested that they were derived from a single bacterial clone. Phylogenetic analysis based on 16S rRNA gene sequences showed that its closest relatives were members of cluster XIVa of the subphylum of Gram-positive bacteria and that the closest related type strain was L1-92 (94.5 % similarity). Similarity levels of 96–98 % with sequences from uncultured bacteria from human stool samples were observed. On the basis of morphological, biochemical and phylogenetic characteristics, this strain is assigned to a novel species in the genus , for which the name sp. nov. is proposed. The type strain is 35-7 (=LMG 24724 =DSM 22094). An emended description of the genus is also provided.
