Changde warehouse rice in Hunan was taken as the research object, microbial experiments and quality testing were carried out, and major molds in rice were identified using ITS sequence analysis technology. The results showed that the species were identified by molecular biology methods. After three samplings, 13 different molds were isolated from rice: Rhizopodiformis isolate HX-1, Aspergillus oryzae isolate NL5, Lichtheimia ramosa strain AUMC 7691, Aspergillus niger isolate SZ8M-14, Aspergillus fumigatus strain JXL-108Y-1, Aspergillus flavus i...
