title: Bowmanella dokdonensis sp. nov., a novel exoelectrogenic bacterium isolated from the seawater of Dokdo, Korea.
abstract: A Gram-negative, motile, and rod-shaped bacterial strain, UDC354(T), was isolated from the seawater of Dokdo, Korea. The strain UDC354(T) displayed optimal growth at 30-37 °C in the presence of 0-2 % (w/v) NaCl at pH 8. Strain UDC354(T) was found to contain Q-8 and 9 as isoprenoid ubiquinones; C16:0 (22.9 %), summed feature 3 (iso-C15:0 2-OH and C16:1 ω7c) (21.4 %) and C18:1 ω7c (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(T) belongs to the genus Bowmanella, of the family Alteromonadaceae, and is closely related to Bowmanella pacifica W3-3A(T) (95.2 %) and Bowmanella denitrificans BD1(T) (95.0 %). It was found that strain UDC354(T) is exoelectrogenic and is capable of generating 6.6 μW/cm(3) 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(T) (=KCTC 42147(T)=JCM 30855(T)).
