The cellular fatty acid compositions of strains of Pseudomonas aeruginosa, P. cepacia, and P. maltophilia were determined by gas-liquid chromatography. A variety of acids was detected in these organisms, including branched and straight-chain acids, cyclopropane, and hydroxy acids. Comparison of the presence and relative amounts of these acids was useful in distinguishing the three species. Three branched-chain hydroxy acids not found in other bacteria were present in P. maltophilia and were identified by gas chromatography, mass spectrometry, and infrared spectroscopy.
通过气液色谱法测定了铜绿假单胞菌、洋葱伯克霍尔德菌和嗜麦芽窄食单胞菌菌株的细胞脂肪酸组成。在这些微生物中检测到了多种酸，包括支链和直链酸、环丙烷酸和羟基酸。比较这些酸的存在情况和相对含量有助于区分这三个菌种。嗜麦芽窄食单胞菌中存在三种在其他细菌中未发现的支链羟基酸，并通过气相色谱、质谱和红外光谱进行了鉴定。
