Abstract

The phospholipid headgroup and fatty acid compositions of a halotolerant Planococcus sp. (strain A4a) were examined when cells were grown in the presence of high concentrations of a variety of salts. The fatty acid composition of Planococcus sp. strain A4a was altered primarily as a function of the osmolality of the growth medium. The phospholipid headgroup composition was influenced by both the osmolality of the growth medium and the nature of the cation species present. An increase in the cardiolipin/phosphatidylglycerol molar ratio was detected when cells were grown in the presence of high concentrations of monovalent cations.

摘要

当嗜盐动性球菌属(菌株A4a)在高浓度的各种盐存在的情况下生长时,对其磷脂头部基团和脂肪酸组成进行了检测。动性球菌属菌株A4a的脂肪酸组成主要随生长培养基的渗透压而变化。磷脂头部基团组成受生长培养基的渗透压和存在的阳离子种类的性质两者影响。当细胞在高浓度单价阳离子存在的情况下生长时,检测到心磷脂/磷脂酰甘油摩尔比增加。
