Abstract
A novel Gram-stain-negative, aerobic and rod-shaped bacterial strain, designated as HK4-1T, was isolated from mangrove sediments in Hong Kong, PR China. Based on 16S rRNA gene sequence data, strain HK4-1T was found to belong to the genus Novosphingobium , family Erythrobacteraceae , and showed high similarity to Novosphingobium chloroacetimidivorans BUT-14T (96.88 %) and Novosphingobium indicum H25T (96.88 %). The G+C content of the whole genome of strain HK4-1T was 64.05 mol%. The major fatty acids were C16 : 0, C18 : 1 ω7c and summed feature 3 (C16 : 1 ω7c and/or C16 : 1 ω6c). The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, sphingoglycolipid and two unknown lipids. The predominant respiratory quinone was Q-10. Based on genomic, phylogenetic, phenotypic, physiological and chemotaxonomic data, strain HK4-1T should be classified as representing a novel species of the genus Novosphingobium , for which the name Novosphingobium mangrovi sp. nov. is proposed. The type strain of Novosphingobium mangrovi sp. nov. is HK4-1T (=MCCC 1K08252T=JCM 35764T).
