摘要:  通过气相色谱对15株革兰氏阴性致病菌的细胞脂肪酸组分进行分析,可以清晰地分出不同的属其脂肪酸组分有明显地差异,同一属中不同的种也表现出一定的差异,地方菌株与模式菌株具有相同的脂肪酸组分,可以根据脂肪酸组分对食品中致病菌进行快速鉴定。

Abstract:  The components of cellular fatty acids of 15 strains of Gram-negative pathogenic bacteria which analyzed by gas chromatography, are clearly dissimilar in different genera, partial dissimilarity in the same genus and the same in type strains and local strains. So that can be used to identify pathogenic bacteria in the food.

Key words:  , gas chromatography; fatty acid; pathogenic bacterium; type strain; local strain;
