The short-chain acids of 36 strains of Pseudomonas grown on Trypticase soy agar were determined by gas-liquid chromatography. Distinct acid profiles were observed for each of the eight species tested. Propionic, isobutyric, and isovaleric acids were the principal acids detected in media extracts of P. maltophilia, P. cepacia, P. pseudoalcaligenes, P. diminuta, and P. vesiculare. The presence and relative amounts of the isobutyric and isovaleric acids clearly distinguished P. maltophilia, P. pseudoalcaligenes, and P. cepacia from other species. P. diminuta could be distinguished from P. vesiculare by the production of glutaric acid; P. testosteroni was the only species tested which produced relatively large amounts of phenylacetic acid.
通过气液色谱法测定了在胰蛋白酶大豆琼脂上生长的36株假单胞菌的短链酸。在所测试的八个菌种中,每个菌种都观察到了独特的酸谱。丙酸、异丁酸和异戊酸是嗜麦芽窄食单胞菌、洋葱伯克霍尔德菌、类产碱假单胞菌、缺陷假单胞菌和泡囊假单胞菌培养基提取物中检测到的主要酸。异丁酸和异戊酸的存在及其相对含量清楚地将嗜麦芽窄食单胞菌、类产碱假单胞菌和洋葱伯克霍尔德菌与其他菌种区分开来。缺陷假单胞菌可通过产生戊二酸与泡囊假单胞菌区分开来;睾丸酮假单胞菌是所测试的唯一产生相对大量苯乙酸的菌种。
