Cochleicola gelatinilyticus gen. nov., sp. nov., Isolated from a Marine Gastropod, Reichia luteostoma

J Microbiol Biotechnol. 2016 Aug 28;26(8):1439-45. doi: 10.4014/jmb.1604.04083.


A yellow, rod-shaped, non-motile, gram-negative, and strictly aerobic bacterial strain, designated LPB0005(T), was isolated from a marine gastropod, Reichia luteostoma. Here the genome sequence was determined, which comprised 3,395,737 bp with 2,962 protein-coding genes. The DNA G+C content was 36.3 mol%. The 16S rRNA gene sequence analysis indicated that the isolate represents a novel genus and species in the family Flavobacteriaceae, with relatively low sequence similarities to other closely related genera. The isolate showed chemotaxonomic properties within the range reported for the family Flavobacteriaceae, but possesses many physiological and biochemical characteristics that distinguished it from species in the closely related genera Ulvibacter, Jejudonia, and Aureitalea. Based on phylogenetic, phenotypic, and genomic analyses, strain LPB0005(T) represents a novel genus and species, for which the name Cochleicola gelatinilyticus gen. nov., sp. nov. is proposed. The type strain is LPB0005(T) (= KACC 18693(T) = JCM 31218(T)).

Keywords: Cochleicola gelatinilyticus; Flavobacteriaceae; novel species; taxonomy.
