Abstract
The fatty acid composition of the cell membrane of the barophilic marine bacterium CNPT3 was found to vary as a function of pressure. Greater amounts of unsaturated fatty acids were present in bacteria growing at higher pressures. The results suggest adaptations in the membrane lipids to environmentally relevant pressures. This response to pressure appears to be analogous to temperature-induced membrane adaptations observed in other organisms.
摘要
嗜压海洋细菌CNPT3细胞膜的脂肪酸组成被发现会随压力而变化。在较高压力下生长的细菌中存在更多的不饱和脂肪酸。结果表明膜脂对与环境相关压力的适应性。这种对压力的反应似乎类似于在其他生物体中观察到的温度诱导的膜适应性。
