Description of sp. nov., sp. nov. and sp. nov., isolated from shellfish, emended description of the genus and proposal of fam. nov. Free

Abstract

Three novel moderately anaerobic, thermophilic, rod-shaped bacterial strains, KY38, KY46 and KA13, were isolated from shellfish collected on the Pacific coastline of Enoshima, Japan. Phylogenetic analysis of the 16S rRNA gene sequences indicated that these bacteria belong to the genus , sharing sequence similarities of 97.8 % (KY38), 96.4 % (KY46) and 93.3 % (KA13) with the type strain of , the only species of the genus with a validly published name. These isolates reduced nitrate and grew optimally at 55–60 °C. Strains KY38 and KA13 formed endospore-like structures in the terminal or subterminal part of their cells at low frequencies. Genomic DNA G+C contents were 68.8 (KY38), 67.2 (KY46) and 67.1 (KA13) mol%. The isolates all presented the predominant menaquinone MK-6, major fatty acids iso-C, C and iso-C and the major polar lipids phosphatidylglycerol, phosphatidylethanolamine and unknown glycol-containing phospholipids. On the basis of their morphological, physiological and phylogenetic properties, strains KY38, KY46 and KA13 represent three novel species, for which the names sp. nov. (type strain KY38 = DSM 27624 = KCTC 4567 = JCM 15048), sp. nov. (type strain KY46 = DSM 27625 = KCTC 4568 = JCM 15996) and sp. nov. (type strain KA13 = DSM 27138 = KCTC 4569 = JCM 15997) are proposed. An emended description of the genus is also presented. The phylogenetic distinctiveness of the genus indicates its affiliation with a novel family, for which the name fam. nov. is proposed.
