Abstract:
:A group of five Gram-negative, aerobic, halotolerant, non-pigmented bacteria isolated from shallow sediment samples and invertebrate specimens collected from the Gulf of Alaska and the Sea of Japan was subjected to taxonomic study. On the basis of 16S rRNA gene sequence analysis, the novel isolates were affiliated to the genus Cobetia, sharing the highest sequence similarity of 99.3-99.9 % with Cobetia marina DSM 4741(T). DNA-DNA hybridization experiments between and among the novel strains and C. marina DSM 4741(T) and Cobetia crustatorum JCM 15644(T) revealed that the five strains represent three separate genospecies, which could be differentiated in their morphological, physiological and biochemical characteristics. Halomonas halodurans NBRC 15607(T) was included in this study as it has recently been reported to exhibit high 16S rRNA gene sequence similarity to C. marina DSM 4741(T), and it showed a high DNA relatedness value of 96 % with C. marina DSM 4741(T), indicating that they belong to the same species. On the basis of phylogenetic analysis, DNA-DNA hybridization and phenotypic characterization, three novel species are proposed, named Cobetia amphilecti sp. nov. (type strain KMM 1561(T) = NRIC 0815(T) = CCUG 49560(T)), Cobetia litoralis sp. nov. (type strain KMM 3880(T) =NRIC 0814(T) =CCUG 49563(T)) and Cobetia pacifica sp. nov. (type strain KMM 3879(T) = NRIC 0813(T) = CCUG 49562(T)). It is also proposed that Halomonas halodurans is a later heterotypic synonym of Cobetia marina, and emended descriptions of the genus Cobetia and the species Cobetia marina are provided.
