从中国香港的红树林沉积物中分离到一株革兰氏阴性好氧杆状细菌，命名为HK 4 - 1 T。根据16 S rRNA基因序列分析，菌株HK 4 - 1 T属于赤藓科新鞘氨醇菌属，与新鞘氨醇菌chloroacetimidivorans BUT-14 T（96.88%）和印度新鞘氨醇菌H25 T（96.88%）具有较高的相似性。HK 4 - 1 T全基因组G+C含量为64.05mol%。主要脂肪酸为C16：0、C18：1 ω 7 c和总特征3（C16：1 ω 7 c和/或C16：1 ω6c）。主要极性脂质为磷脂酰乙醇胺、磷脂酰甘油、磷脂酰胆碱、鞘糖脂和两种未知脂质。主要的呼吸醌是Q-10。基于基因组、系统发育、表型、生理学和化学分类学数据，菌株HK 4 - 1 T应被分类为代表新鞘氨醇菌属的一个新种，并建议将其命名为Novosphingobium mangrovi sp. nov.。模式菌株为HK 4 - 1 T（=MCCC 1 K 08252 T =JCM 35764 T）。
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).
