The present invention discloses anJAAS-32 and use thereof in preparation of a larval Hermetia illucens paste protein peptide. TheJAAS-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. A larval Hermetia illucens paste is subjected to enzymatic fermentation by theJAAS-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, andare 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.

The present invention provides a preparation method for a modified cathode of an MEC-AD system and application of the system with high efficiency and low energy consumption. A NiCo-BDC hydrothermal carbon composite MOF material is designed and used for modifying a cathode, which can remove COD more rapidly compared with traditional AD. A wind energy and light energy complementary power generation device is used for energy supply of the MEC-AD system, and energy consumption is further reduced by setting an intermittent power supply mode. The intermittent power supply achieves higher energy recovery efficiency while obtaining higher performance, can effectively reduce energy consumption of the MEC-AD system, is conducive to more convenient configuration of a power generation and energy supply device using clean energy, and has a good application prospect in reducing COD in organic wastewater with low energy consumption and high efficiency.
