Abstract
The present invention discloses an Aspergillus oryzae JAAS-32 and use thereof in preparation of a larval Hermetia illucens paste protein peptide. The Aspergillus oryzae JAAS-32 was deposited in Guangdong Microbial Culture Collection Center (GDMCC) on Aug. 10, 2023 with an accession number of GDMCC No: 63725, classified and named Aspergillus oryzae. A larval Hermetia illucens paste is subjected to enzymatic fermentation by the Aspergillus oryzae JAAS-32 provided by the present invention for 20-40 hours. The content of the protein peptide (<10 kDa) is 1.53 times that of an untreated group; the content of free amino acids is 1.41 times that of the untreated group; the total antioxidant activity is 1.35 times that of the untreated group. Diameters of inhibition zones against Staphylococcus aureus, Escherichia coli, and Vibrio alginolyticus are 1.62, 1.17, and 1.45 times those of the untreated group, respectively. The strain is cultured readily, fast in growth, and well-adapted. A low-cost, easy-to-operate, and efficient method for enhancing antibacterial performance of the larval Hermetia illucens paste can be established on the basis of the strain.
