Abstract
Solvent-tolerant and -sensitive Pseudomonas putida strains were studied to determine their cell envelope changes following exposure to o-xylene. Both strains produced trans-unsaturated fatty acids. The tolerant strain showed an increase in total fatty acids, an increase in saturated fatty acids, and modified lipopolysaccharide. It is suggested that these envelope modifications aid in survival at high concentrations of organic solvents.
摘要
研究了耐溶剂和敏感的恶臭假单胞菌菌株，以确定它们在接触邻二甲苯后细胞包膜的变化。两种菌株都产生了反式不饱和脂肪酸。耐溶剂菌株的总脂肪酸增加，饱和脂肪酸增加，脂多糖发生了改变。这表明这些包膜的修饰有助于在高浓度有机溶剂中存活。
