Novosphingobium mangrovi sp. nov., isolated from mangrove sediment

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 omega 7c and summed feature 3 (C16:1 omega 7c and/or C16: 1 omega 6c). 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).
