Moritella sagamensis sp. nov., a psychrophilic biosurfactant-producing bacterium isolated from the mesopelagic water sample
Two novel strains of the genus Moritella, i.e., F1 and F3, were isolated from a 500-m depth in the Sagami Trough, Japan. Our analyses revealed that these strains share the same 16S rRNA gene sequence, and in a BlastN analysis the sequence showed 99.66% similarity with that of the most closely related strain M. marina ATCC 15381. Based on the results of our phylogenetic, physiological, and phenotypic analyses, we propose a novel species to accommodate strains F1 and F3: Moritella sagamensis sp. nov. The type strain of Moritella sagamensis is F1.
