嗜压海洋细菌CNPT 3的细胞膜的脂肪酸组成被发现作为压力的函数而变化。大量的不饱和脂肪酸存在于在较高压力下生长的细菌中。结果表明，在膜脂适应环境相关的压力。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。
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 analogs to temperature-induced membrane adaptations observed in other organisms.
