Abstract

Phospholipid compositions of 20 strains of marine and estuarine bacteria were determined. Results showed that phospholipids of marine bacteria differed very little from those of nonmarine organisms with phosphatidylethanolamine, phosphatidylglycerol, and diphosphatidylglycerol being the predominant phospholipids in all strains examined. Lyso-phosphatidylethanolamine occurred in significant quantities among a number of the marine bacteria, and two of the isolates contained significant quantities of poly-beta-hydroxybutyrate. Effects of age and growth temperature on the phospholipid composition were also investigated. It is suggested that phylogenetic relationships among bacteria may be correlated with phospholipid composition.

摘要

测定了20株海洋和河口细菌的磷脂组成。结果表明,海洋细菌的磷脂与非海洋生物的磷脂差异很小,磷脂酰乙醇胺、磷脂酰甘油和二磷脂酰甘油是所有检测菌株中的主要磷脂。溶血磷脂酰乙醇胺在许多海洋细菌中大量存在,并且其中两个分离株含有大量的聚-β-羟基丁酸酯。还研究了年龄和生长温度对磷脂组成的影响。有人提出,细菌之间的系统发育关系可能与磷脂组成相关。
