Abstract

A Gram-negative, strictly anaerobic, halophilic, motile, sporulating and rod-shaped bacterium, designated strain HY-42-06, was isolated from tidal flat sediment from Ganghwa Island in South Korea. The isolate produced glycerol, ethanol and CO as fermentation end-products from glucose. Strain HY-42-06 grew optimally at 35 °C, pH 7·5 and 3 % (w/v) artificial sea salts. No growth was observed in the absence of sea salts. In phylogenetic analyses based on 16S rRNA gene sequence, strain HY-42-06 showed a distinct phyletic line within the members of cluster I of the order . The closest phylogenetic neighbour to strain HY-42-06 was ATCC 17861 (94·91 % 16S rRNA gene sequence similarity). Several phenotypic characters readily differentiate the tidal flat isolate from phylogenetically related clostridia. On the basis of polyphasic evidence, strain HY-42-06 should be classified as a representative of a novel species, for which the name sp. nov. is proposed. The type strain is HY-42-06 (=IMSNU 40127=KCTC 5146=JCM 13193).
