景芝镇高温大曲微生物群落与理化性质和感官品质的相关性分析
Correlation analysis of microbial community,physical and chemical properties,and sensory quality of high temperature Daqu in Jingzhi Town
摘要
Abstract
This study employed PacBio SMRT sequencing and pure culture technology to analyze the microbial community composi-tion of high-temperature Daqu.Conventional physicochemical analyses and bioassays were conducted to assess its physicochemical proper-ties and sensory qualities,as well as to investigate correlations with the dominant microorganisms.The results of the PacBio SMRT sequen-cing indicated that the bacterial community in high-temperature Daqu from Jingzhi Town exhibited significantly greater species richness and diversity compared to the fungal community(P<0.05).Species-level analysis revealed that Kroppenstedtia sanguinis was the predominant bacterial species,with an average relative abundance of 35.60%.The main fungal species identified were Thermomyces lanuginosus,Ther-moascus crustaceus,and Thermoascus aurantiacus,with average relative abundances of 47.97%,16.81%,and 15.59%,respectively.Pure culture results indicated that the culturable microorganisms were primarily represented by Bacillus licheniformis and Bacillus amyloliq-uefaciens.Correlation analysis suggested that the bacterial taxa may have a more significant influence on the physicochemical properties and sensory quality of high-temperature Daqu from Jingzhi Town.This study enhances the understanding of the microbial community structure associated with high-temperature Daqu and provides valuable microbial strains that could support improvements in the Daqu production process and its quality.关键词
