Abstract |
A Gram-staining-negative, thin rod-shaped, 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), 5.0–10.0 (optimum pH 6.5), and 1–5%,
respectively. The major fatty acids were iso-C15:0 (30%) and
iso-C15:0 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 (92.8% sequence identity), Clostridiisalibacter
paucivorans (92.6%), and Brassicibacter mesophilus
(92.4%). 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. |
