Abstract

A strictly anaerobic, mesophilic, endospore-forming bacterium, designated strain HY-35-12, was isolated from a soil sample in Jeju, Korea. Cells of this isolate were Gram-positive, motile rods that formed oval to spherical terminal spores. Strain HY-35-12 grew optimally at 30 °C, pH 7·0 and 0–0·5 % (w/v) NaCl. The isolate produced pyruvate, lactate, acetate, formate and hydrogen as fermentation end products from glucose. The G+C content of DNA of the isolate was 41 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the organism formed a monophyletic clade with and in cluster XIVa of the genus . The closest phylogenetic neighbour was , with 96·65 % 16S rRNA gene sequence similarity. Several physiological and chemotaxonomic properties were identified that enable strain HY-35-12 to be distinguished from phylogenetically related clostridia. On the basis of polyphasic characteristics, it is proposed that strain HY-35-12 (=IMSNU 40003=KCTC 5026=DSM 15929) represents a novel species, sp. nov.
