  • Publication number: 20220079160
    Abstract: A green method and application for inhibiting toxin-producing Aspergillus flavus are provided. After a ?-Fe2O3 nanorod nanomaterial is brought into contact with spores of toxin-producing Aspergillus flavus without germination or after germination for irradiation, under irradiation of a light source, inhibiting growth of the toxin-producing Aspergillus flavus to lower a content of aflatoxin. In the disclosure, the growth of hyphae and the germination of spores of the Aspergillus flavus may be effectively inhibited, the growth of the toxin-producing Aspergillus flavus may be inhibited, the pollution of agricultural products such as peanuts by the Aspergillus flavus may be effectively prevented, and the content of aflatoxin may be reduced, so that the disclosure has broad application prospects.

  • Patent number: 11098278
    Abstract: The invention belongs to the field of chemical analysis and detection, and specifically relates to a pretreatment method for LC-MS detecting metabolomics of Aspergillus flavus. The method includes: culturing a strain of Aspergillus flavus; quenching the Aspergillus flavus; disrupting the cell membrane of Aspergillus flavus, and extracting a metabolome. The invention adopts a cold glycerol buffer solution combined with a rapid filtration method for quenching, and a MeOH/DCM/ACN/EA/HCOOH mixture is used as an metabolome extract, thereby achieving the object of efficiently extracting different polar compounds, and metabolome compound coverage is high; pretreatment of the cell metabolomics of Aspergillus flavus by the method of the invention can ensure the repeatability and stability of the metabolomics analysis method and reduce the false positive of the test results.
