Abstract:
A gas chromatographic analysis method was employed to determine the cellular fatty acids (CFAs)profiles of the spores of some aerobic endospore4orming bacilli. Purified spore cultures of 51 experimentas strains were processed to acquire whole cell fatty acids methyl esters for the subsequent gas chromatographic analysis,and the corresponding vegetative cells were set as control. The reproducibility study of spore fatty acids revealed that,the fatty acids components of spores were stable enough for research purpose,provided under standardized experimentas procedure. The dendrograms obtained by cluster analysis provided some meaningful taxonomic information of the experimental strains. The fatty acids analysis of spores seemed to be a promising supplementary tool for the chemotaxonomic research of aerobic endospore-forming bacilli.
