| Popis: | A Gram-stain-negative, yellow-pigmented, rod-shaped, strictly aerobic, non-motile bacterium, designated BDHS18T, was isolated from the sediment of the Hasuhai Lake, China. Phylogenetic analysis based on 16S rRNA gene sequences revealed that this strain belongs to the genus Moheibacter in the family Flavobacteriaceae and its closest relative was Moheibacter sediminis JCM 19634T (96.0%), followed by Moheibacter stercoris DSM 29388T (95.3%). Cells of strain BDHS18T were catalase-positive and oxidase-negative. Strain BDHS18T was found to grow optimally at 28–33 ℃, pH 7.5–8.0, and in the presence of approximately 1.0% (w/v) NaCl. Major cellular fatty acids were iso-C15:0, iso-C17:0 3-OH, Summed feature 4 and Summed feature 9. The predominant respiratory quinone was MK-6. The predominant polar lipids in strain BDHS18T were phosphatidylethanolamine, phosphatidylglycerol, one unidentified aminolipid and one unidentified lipid. The DNA G + C content was 36.9 mol%. According to the phylogenetic analysis, physiological and phenotypic characteristics, strain BDHS18T represents a novel species of the genus Moheibacter, for which the name Moheibacter lacus sp. nov. is proposed. The type strain is BDHS18T (= KCTC 72160T = MCCC 1H00369T). |
