摘要
使用气相色谱技术分析４３株厌氧菌的代谢产物，发现脆弱拟杆菌产生乙酸、甲酸、丙酸、异丁酸、异戊酸和琥珀酸，而梭杆菌产生丁酸、乙酸和丙酸，双歧杆菌产生乙酸和乳酸，乳杆菌产生乳酸，使用气相色谱分析菌的代谢产物可对菌属进行鉴定。值得临床推广使用。
orty three stains of anaerobic bacterial metabolic products were analyzed by gas一liguid chromatography It was found that,the B. fragilis group produced acetic,formic,propionic,isobutyric,isovaleric and succinic acids,the fusobacterium produced butyric,acetic and propionic acids,the bifido bifidobacterium produced acetic and lactic acid, and the lactobacillus produced lactic acid.The use of gas一liquid chromatography for the analysis of bacterial metabolic products provides a decisive data for the identification of bacterial strains and its widespread clinical application is recommended.
