Identification of beer-spoilage bacterium and analysis of its membrane fatty acids composition
摘要
Abstract
A total of 11 strains of beer-spoilage bacteria were isolated from draft beer.The homology of 16S rRNA was analyzed and phylogenetic tree was structured for these 11 beer-spoilage bacteria.These 11 beer-spoilage bacteria were all classified into Lactobacillus genus,including Lactobacillus plantarum,Lactobacillus parabuchneri and Lactobacillus brevis.Variation of beer-spoilage bacteria membrane lipid composition was consistent with the result of 16S rRNA.The contents of straight chain unsaturated fatty acids and C18 and C20 fatty acids of BN01,BN02 and BN03 were increased with increase of beer content.These results not only classified and identified beer-spoilage bacteria but also expound tolerance mechanism of beer environmental stress based on regulation of fatty acids of beer bacteria membrane.关键词
