sp. nov., of the family , isolated from a tidal flat Free

Abstract

A Gram-stain-negative, non-motile, aerobic and rod-shaped bacterium, designated strain MME-001, was isolated from the tidal flat of Muui-do in the Republic of Korea. Phylogenetic trees based on the 16S rRNA gene sequence showed that strain MME-001 belonged to the genus in the family and that it shared the highest 16S rRNA gene sequence similarity with GJMS-35 (98.0 % similarity of the 16S rRNA gene). Growth of strain MME-001 occurred in the presence of 1.0–7.0 % (w/v) NaCl at 15−40 °C and pH 7.0–9.0, with optimal growth in the presence of 2.0–3.0 % (w/v) NaCl at 25–30 °C and pH 7.0. Ubiquinone-10 was the major respiratory quinone. Major polar lipids were phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol and an unidentified lipid. The major cellular fatty acids were C 7 and C. The genomic DNA G+C content was 62 mol%. DNA-DNA hybridization values between strain MME-001 and KCTC 42111, ‘’ KCTC 32460, KCTC 22690, KCTC 12737 and KACC 17214 was 36±5, 57±7, 34±4, 18±5 and 21±3 %, respectively. Based on the phenotypic and phylogenetic taxonomical properties, this strain MME-001 represents a novel species of the genus for which the name sp. nov. is proposed. The type strain is MME-001 (=KCCM 43133=JCM 30751).
