- Abstract
A Gram-negative, motile, and rod-shaped bacterial strain, UDC354, was isolated from the seawater of Dokdo, Korea. The strain UDC354 displayed optimal growth at 30-37 °C in the presence of 0-2 % (w/v) NaCl at pH 8. Strain UDC354 was found to contain Q-8 and 9 as isoprenoid ubiquinones; C (22.9 %), summed feature 3 (iso-C 2-OH and C ω7 c) (21.4 %) and C ω7 c (12.2 %) as the major fatty acids; and diphosphatidylglycerol, phosphatidylglycerol, and phosphatidylethanolamine as the major polar lipids. The DNA G+C content was found to be 54.1 mol %. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain UDC354 belongs to the genus Bowmanella, of the family Alteromonadaceae, and is closely related to Bowmanella pacifica W3-3A (95.2 %) and Bowmanella denitrificans BD1 (95.0 %). It was found that strain UDC354 is exoelectrogenic and is capable of generating 6.6 μW/cm in marine broth in the microbial fuel cells. Based on the analysis of the phenotypic, chemotypic and phylogenetic characteristics, a new species, Bowmanella dokdonensis sp. nov. is proposed. The type strain is UDC354 (=KCTC 42147=JCM 30855).
