Research progress on community structure and functional microorganisms of pit mud

Abstract:

Pit mud is a characteristic fermentation carrier of Luzhou flavor liquor, which contains many kinds of flavor producing microorganisms that have an important influence on the style and quality of Luzhou flavor liquor. This study summarizes and compares the microbial activities of cellar mud of different ages, different flavor liquor producing areas and cellar mud microorganisms of different quality, and then analyzes the function of these microbes in pit mud. The purpose of this study is to provide a new thought for the research of cellar mud microorganisms, for improving the quality and flavor composition of Luzhou flavor liquor. It is helpful to promote the research of microbe in pit mud, and deepen the knowledge of pit mud.
