Marinomonas属的成员以其环境适应性和代谢多功能性而闻名,与抗冻剂相关的大量蛋白质,耐渗透压,糖酶和多种次级代谢产物。使用Marinomonas属中的30个参考基因组序列进行了针对次级代谢物和直向同源蛋白的比较基因组分析。在这项研究中,革兰氏染色阴性,杆状,非鞭毛和严格的需氧细菌,指定为菌株E8T,从威海沿海的红藻(Gelidiumamansii)中分离出来,中国。在25-30°C的温度下观察到菌株E8T的最佳生长,pH6.5-8.0和1-3%(w/v)NaCl。DNAG+C含量为42.8mol%。主要的类异戊二烯醌是Q-8,主要的脂肪酸是C16:0,求和特征3和求和特征8。主要的极性脂质是磷脂酰甘油(PG)和磷脂酰乙醇胺(PE)。根据这项多相分类研究获得的数据,菌株E8T应被视为Marinomonas属的新物种,为此提出了名为Marinomonasalgarum的名称。菌株类型为E8T(=KCTC92201T=MCCC1K07070T)。
Members of the genus Marinomonas are known for their environmental adaptation and metabolically versatility, with abundant proteins associated with antifreeze, osmotic pressure resistance, carbohydrase and multiple secondary metabolites. Comparative genomic analysis focusing on secondary metabolites and orthologue proteins was conducted with 30 reference genome sequences in the genus Marinomonas. In this
study, a Gram-stain-negative, rod-shaped, non-flagellated and strictly aerobic bacterium, designated as strain E8T, was isolated from the red algae (Gelidium amansii) in the coastal of Weihai, China. Optimal growth of the strain E8T was observed at temperatures 25-30 °C, pH 6.5-8.0 and 1-3% (w/v) NaCl. The DNA G + C content was 42.8 mol%. The predominant isoprenoid quinone was Q-8 and the major fatty acids were C16:0, summed feature 3 and summed feature 8. The major polar lipids were phosphatidylglycerol (PG) and phosphatidylethanolamine (PE). Based on data obtained from this polyphasic taxonomic
study, strain E8T should be considered as a novel species of the genus Marinomonas, for which the name Marinomonas algarum is proposed. The type strain is E8T (= KCTC 92201T = MCCC 1K07070T).
