Litoribrevibacter albus gen. nov. sp. nov., isolated from coastal seawater, Fujian province, China
文摘
A Gram-stain negative, short rod-shaped aerobic bacterium with flagella, designated strain Y32T, was isolated from coastal seawater in Xiamen, Fujian Province of China. 16S rRNA gene sequence comparisons showed that strain Y32T is a member of the family Oceanospirillaceae, forming a distinct lineage with species of the genus Litoribacillus. The 16S rRNA gene sequence similarities between strain Y32T and other strains were all less than 94.0?%. Strain Y32T was found to grow optimally at 28?°C, at pH 7.0-.0 and in the presence of 4-?% (w/v) NaCl. The major fatty acids were identified as Summed Feature 3 (comprising C16:1 ω7c and/or C16:1 ω6c, 49.4?%), C16:0 (17.7?%), C14:0 (6.9?%) and C18:1 ω9c (5.4?%). The major respiratory quinone was identified as ubiquinone-8 (Q-8). The major polar lipids were identified as diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol. The DNA G+C content of strain Y32T was determined to be 55.6?mol%. According to its morphology, physiology, fatty acid composition, polar lipids composition and 16S rRNA gene sequence data, strain Y32T represents a novel species of a new genus in the family Oceanospirillaceae, for which the name Litoribrevibacter albus gen. nov. sp. nov. is proposed. The type strain of Litoribrevibacter albus is Y32T (=MCCC 1F01211T=NBRC 110071T).
