Ma.ri.ha 'bi.tans。l .中性粒细胞。n.maresea;l .部分。adj.habitansinhabiting;n .名词，名词用作名词。海洋的居民。“放线菌”/放线菌/微球菌/胞内菌科/ marihabitan细胞是革兰氏染色阳性、非运动、非孢子形成、过氧化氢酶阳性、需氧、不规则的短杆状和球菌，从表层海水、深海海水和海洋海绵中分离出来，宽0.9-1.4 μm，长1.2-1.7 μm。该肽聚糖为A型，包含so - A2pm、丙氨酸和谷氨酸。细胞壁糖是半乳糖、葡萄糖和核糖。没有霉菌酸。主要的甲基萘醌是MK‐8（H4）。磷脂包括磷脂酰甘油、一种未知的磷脂、二磷脂酰甘油和磷脂酰肌醇甘露糖苷。在系统发育上，该属是内孢科的一员。在基于16S rRNA基因的系统发育树上，最接近的分类群是kribbia属。模式种Marihabitans asiaticumHG667TandKribbia dieselivoransN113T之间的16S rRNA基因序列相似性值为96.3%。Marihabitansis与kribbiaby的区别在于，在主要的脂肪酸谱中缺乏饱和脂肪酸。模式种的基因组序列为2,953,873 bp，预测了2,694个蛋白质编码基因。计算得到的G + C含量为71.1%。DNA G + C含量（mol%）： 71.1%（基因组序列）；70(高效液相色谱)。模式种：Marihabitans asiaticumKageyama et al. 2008。
Ma.ri.ha'bi.tans. L. neut. n.maresea; L. part. adj.habitansinhabiting; N.L. adj. used as a neut. subst.Marihabitansinhabitant of the sea.“Actinobacteria” / Actinobacteria / Micrococcales / Intrasporangiaceae / MarihabitansCells are Gram‐stain‐positive, nonmotile, non‐spore‐forming, catalase‐positive, aerobic, and irregular short rods and cocci isolated from surface seawater, deep seawater, and marine sponges, which are 0.9–1.4 μm wide and 1.2–1.7 μm long. The peptidoglycan is of the A type and containsmeso‐A2pm, alanine, and glutamic acid. The cell‐wall sugars are galactose, glucose, and ribose. Mycolic acids are absent. The major menaquinone is MK‐8(H4). The phospholipids comprise phosphatidylglycerol, an unknown phospholipid, diphosphatidylglycerol, and phosphatidylinositol mannosides. Phylogenetically, the genus is a member of the familyIntrasporangiaceae. Most closely related taxon is the genusKribbiain the 16S rRNA gene‐based phylogenetic tree. The similarity value of the 16S rRNA gene sequence is 96.3% between the type species,Marihabitans asiaticumHG667TandKribbia dieselivoransN113T.Marihabitansis distinguishable fromKribbiaby the absence of saturated fatty acids in the predominant fatty acid profile. The genome sequence of the type species is 2,953,873 bp, and 2,694 protein‐coding genes are predicted. The calculated G + C content is 71.1%.DNA G + C content (mol%): 71.1% (genome sequence); 70 (HPLC).Type species:Marihabitans asiaticumKageyama et al. 2008VP.
