Study on the Diversity of Fungal Community Structure of Nongxiangxing Daqu in Different Koji-making Seasons
In this paper,the fungal community diversity of Jiannanchun Daqu in different koji-making seasons was analyzed by high-throughput sequencing technology.The results showed that the community structure of Daqu was complex and rich.At the phylum level,Ascomycota,Basidiomycota and Mucoromycota were the dominant,Ascomycota is the absolute dominant fungus in Jiannanchun Daqu.At the genus level,the dominant fungi are Thermoascus,Thermomyces,Aspergillus,Issatchenkia,Candida,Saccharomycopisis,Rhizopus,Monascus.Thermoascus,Candida and other microorganisms showed a certain distribution pattern with the change of entry temperature of Daqu.And there were significant differences in the physical and chemical properties of Daqu in different seasons,which provided a theoretical basis for the production of high-quality Nongxiangxing Daqu.
