Abstract
A Gramstainingnegative thin rodshaped anaerobic bacterium designated MCWD3T was isolated from sediment of the deep sea in Ulleung Basin East Sea Korea The ranges of temperature pH and NaCl for growth of this strain were 15–40°C optimum 29°C 50–100 optimum pH 65 and 1–5 respectively The major fatty acids were isoC150 30 and isoC150 dimethyl acetal 17 The major polar lipids were diphosphatidylglycerol phosphatidylglycerol phosphatidylethanolamine and unidentified aminophospholipids phospholipids and aminolipids The fermentation product from yeast extract was acetate Phylogenetic analysis based on 16S rRNA genes indicated that the isolate was related to Sporosalibacterium faouarense 928 sequence identity Clostridiisalibacter paucivorans 926 and Brassicibacter mesophilus 924 However the isolate was differentiated from these genera by both physiological and chemotaxonomical properties On the basis of a polyphasic taxonomic analysis we propose that MCWD3T represents a novel taxon with the name Abyssisolibacter fermentans gen nov sp nov
