Abstract
A rod-shaped, Gram-stain-negative, aerobic and non-motile bacterium, designated strain Y4T, was isolated from an aquaculture farm in Xiamen, PR China. Strain Y4T had 94.8, 93.3 and 91.8 % 16S rRNA gene sequence similarity to
Paremcibacter congregatus
ZYLT,
Emcibacter nanhaiensis
HTCJW17T and
Luteithermobacter gelatinilyticus
MEBiC09520T, respectively. The genomic DNA G+C content of strain Y4T was 42.7 mol%. The average amino acid identity and percentage of conserved proteins values between strain Y4T and type strains of the family
Emcibacteraceae
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 Y4T required Ca2+, K+ and Mg2+ ions in addition to NaCl for growth. The dominant fatty acids of strain Y4T were summed feature 3 (C16 : 1
ω7c/C16 : 1
ω6c), summed feature 8 (C18 : 1
ω7c/C18 : 1
ω6c) and C14 : 0 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 Y4T (=MCCC 1K06278T=KCTC 82926T) is considered to represent a novel species in a novel genus of the family
Emcibacteraceae
, for which the name Pseudemcibacter aquimaris gen. nov., sp. nov. is proposed.
