基于磷脂脂肪酸分析技术的大曲微生物群落结构多样性研究
Studies on Daqu microbial community structure based on phospholipid fatty acid (PLFA)analysis
摘要
Abstract
The community diversity of microbial in sauce-flavor Daqu,strong-flavor Daqu and light-flavor Daqu were investigated using phospholipid fatty acids (PLFA) as a culture-independent method.The results showed that according to phospholipid fatty acid(PLFA) technique,a total of 18 fatty acids with chain lengths ranging from Ci4 to C20 were detected,including straight-chain PLFA,branched PLFA,monounsaturated PLFA,and the polyunsaturated PLFA.The amount of fungi dominated in the different Daqu.Specifically,gram-positive bacteria (G +) were the main bacteria,the 18∶2ω6,9 and 18∶1ω9 accounted for more than 90％ PLFA.The correlation between the craftwork of Daqu and the microbial community structure was obvious.The community diversity was decreased as the craftwork temperature of Daqu increasing.关键词
