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).
摘要：
一种新的革兰氏染色阴性，需氧和杆状细菌菌株，指定为HK4-1T，是从香港的红树林沉积物中分离出来的，公关中国。基于16SrRNA基因序列数据,HK4-1T菌株被发现属于新鞘植物属，红杆菌科，与氯代乙酸夜蛾BUT-14T（96.88％）和印度夜蛾H25T（96.88％）具有很高的相似性。HK4-1T菌株全基因组的G+C含量为64.05mol%。主要脂肪酸是C16：0，C18：1ω7c和总计特征3（C16：1ω7c和/或C16：1ω6c）。主要极性脂质是磷脂酰乙醇胺，磷脂酰甘油，磷脂酰胆碱，鞘糖脂和两种未知的脂质。主要的呼吸醌是Q-10。基于基因组，系统发育，表型，生理和化学分类学数据，HK4-1T菌株应被归类为代表Novosphingobium属的新物种，名称为Novosphingobiummangrovisp。11月。是提议的。红叶夜蛾的类型菌株。11月。为HK4-1T(=MCCC1K08252T=JCM35764T)。
