abstract：:The effects of pressure and temperature on the fatty acid composition in a barotolerant deep-sea bacterium that had branched-chain fatty acids were examined. The major fatty acids of the strain at atmospheric pressure were iso-C(15:0), C(16:1), iso-C(17:0), and iso-C(17:1). As the growth pressure increased, the propor...
