gen. nov., sp. nov., isolated from an aquaculture farm No Access

Abstract

A rod-shaped, Gram-stain-negative, aerobic and non-motile bacterium, designated strain Y4, was isolated from an aquaculture farm in Xiamen, PR China. Strain Y4 had 94.8, 93.3 and 91.8 % 16S rRNA gene sequence similarity to ZYL, HTCJW17 and MEBiC09520, respectively. The genomic DNA G+C content of strain Y4 was 42.7 mol%. The average amino acid identity and percentage of conserved proteins values between strain Y4 and type strains of the family were 57.9–58.6 % and 44.5–47.6 %, respectively. Optimal growth was observed at 28 °C, at pH 7.0 and with 2 % (w/v) NaCl. The novel strain Y4 required Ca, K and Mg ions in addition to NaCl for growth. The dominant fatty acids of strain Y4 were summed feature 3 (C 7/C 6), summed feature 8 (C 7/C 6) and C 2-OH. The polar lipid profile contained phosphatidylethanolamine, phosphatidyglycerol, three unidentified aminolipids, four unidentified aminophospholipids and two unidentified lipids. Cells contained exclusively ubiquinone Q-10. On the basis of the polyphasic analysis, strain Y4 (=MCCC 1K06278=KCTC 82926) is considered to represent a novel species in a novel genus of the family , for which the name gen. nov., sp. nov. is proposed.
