细胞单糖气相色谱图鉴别细菌的研究

本文介绍细胞单糖毛细管柱气相色谱图的绘制方法，对所得细菌细胞单糖气相色谱图中的某些组分进行分析鉴定，并借助电子计算机对细菌细胞单糖模式进行聚类分析。用上述方法鉴别了24株(5种)芽孢杆菌，均得到满意结果。结果表明，炭疽芽孢杆菌和蜡状芽孢杆菌的单糖图谱有较明显的区别。

Study on the discrimination of bacteria by gas chromatographic profiles of cellular monosaccharides

A procedure for obtaining gas chromatographic (GC) profiles of bacterial cellular monosaccharides was described. Some of the unknown component peaks in these profiles were identified. And, based on the complete linkage cluster analysis with the Euclidean distance coefficient, the interpretation of the resulting cellular monosaccharides of bacteria were performed by mini-computer. By means of this method, the discrimination of 5 species (24 strains) of aerobic endospore-forming bacteria. The results showed that there were defined differences between the profiles of cellular monosaccharides of B. anthracis and B. cereus. This procedure has provided a useful method for the classification and identification of microorganisms, for their physiological and biochemical studies, and for studies on their subcellular components.
