Abstract 

Two bacterial strains, YHK0403T and YHK0508, isolated from soil under a corroded gas pipe line, were revealed as Gram-negative, obligately anaerobic, spore-forming and mesophilic bacteria. The cells were rod-shaped and motile by means of peritrichous flagella. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the isolates were members of the genus Clostridium and were the most closely related to Clostridium scatologenes KCTC 5588T (95.8% sequence similarity), followed by Clostridium magnum KCTC 15177T (95.8%), Clostridium drakei KCTC 5440T (95.7%) and Clostridium tyrobutyricum KCTC 5387T (94.9%). The G + C contents of the isolates were 29.6 mol%. Peptidoglycan in the cell wall was of the A1γ type with meso-diaminopimelic acid. The major polar lipid was diphosphatidylglycerol (DPG), and other minor lipids were revealed as phosphatidylglycerol (PG), phosphatidylethanolamine (PE), two unknown glycolipids (GL1 and GL2), an unknown aminoglycolipid (NGL), two unknown aminophospholipids (PN1 and PN2) and four unknown phospholipids (PL1 to PL4). Predominant fatty acids were C16:0 and C16:1 cis9 DMA. The major end products from glucose fermentation were identified as butyrate (12.2 mmol) and acetate (9.8 mmol). Collectively, the results from a wide range of phenotypic tests, chemotaxonomic tests, and phylogenetic analysis indicated that the two isolates represent novel species of the genus Clostridium, for which the name Clostridium kogasensis sp. nov. (type strain, YHK0403T = KCTC 15258T = JCM 18719T) is proposed.
