The invention discloses an intelligent quintuplet cooperative plasma self-purification robot long-term storage system and a self-adaptive disinfection control method. According to the system, cold plasma, ozone, chlorine dioxide, self-generated nitric oxide and a charge self-purification jump effect are fused, and a dynamic self-purification system with an electric field-gas field-chemical field-intelligent field-thermal field five-dimensional synergistic energy field is constructed. The robot adopts a three-section structural layout and a multi-mode self-adaptive propulsion mechanism, environmental parameters are sensed through AI, discharge power and oxidant release are intelligently regulated and controlled, and precise sterilization, toxicity reduction and mildew prevention in a multi-medium environment are achieved. The system can generate various high-energy active species containing. OH, O, NO, ClO, ONOO and the like, chain splitting decomposition and oxidation mineralization are carried out on mold spores, bacterial cells, aflatoxin and the like, the sterilization rate reaches 99.995%, and the toxin degradation rate exceeds 98%. The system has the characteristics of no residue, low energy consumption, long-acting self-maintenance and the like, is suitable for multiple scenes of grain storage, traditional Chinese medicinal materials, cold chains, farmland, public health and the like, and realizes an intelligent, continuous and chemical-additive-free green storage and dynamic purification system.

This invention belongs to the field of nanomaterials and food packaging, specifically relating to a nanocomposite packaging film with dual functions of degrading toxins and antibacterial properties, and its preparation method. This invention provides a dual-functional composite film for degrading and inhibiting the growth of mycotoxins (aflatoxin B1), and its preparation method. Prussian blue nanoparticles are loaded onto a chitosan-gelatin composite film to prepare a nanomaterial-based dual-functional composite film that not only degrades mycotoxins and kills bacteria, but also allows for timely recycling, further protecting the nutritional components of food.

The application provides a bacillus natto and application thereof in preparation of functional feed for Chinese mitten crab breeding, and belongs to the technical field of aquaculture. Bacillus natto HQ-1 has been preserved in China Center for Type Culture Collection on August 11, 2025, and the preservation number is CCTCC No. M 20251811. Research shows that the bacillus natto has a water product pathogenic bacteria inhibition effect, a toxin degradation capacity and a water body environment purification function which are significantly improved compared with the same strain. The functional feed prepared by fermentation of the strain contains bioactive ingredients such as probiotic live bacteria, free amino acids, antibacterial lipopeptides and polyglutamic acid, can improve the nutritional form of the feed, improve the body weight, disease resistance and feeding rate of the Chinese mitten crab, and help to reduce the content of harmful substances in the aquaculture water body and improve the water body environmental quality. The application provides a new technical approach for green, antibiotic-free and sustainable breeding of the Chinese mitten crab.

The invention discloses a mycotoxin degrading bacterial agent and application thereof in traditional Chinese medicine storage. According to the microbial agent, bacillus coagulans is used as a core degradation component of ochratoxin, tea residues are used as a carrier, microbial cellulose is generated through kombucha mother fermentation to form a nanometer net-shaped structure, meanwhile, rich pores are formed in the tea residues, an efficient adsorption interface and a diffusion channel are provided for OTA, and an ideal colonization microenvironment is provided for bacillus coagulans. Quercetin can inhibit the synthesis of ochratoxin, and forms a synergistic antibacterial effect with a kombucha fermentation product and bacillus coagulans, so that fungal pollution is doubly controlled from the source and in the process. The microbial agent carrier is stable in structure, can realize sustained release of quercetin and continuous biodegradation of thalli, is natural in raw materials, and is suitable for prevention and control of mycotoxin in a traditional Chinese medicine storage process.

This invention discloses a strain of *Trichoderma viride* and its application in antibacterial and toxin degradation, belonging to the field of microbial technology. The *Trichoderma viride* strain is deposited at the China General Microbiological Culture Collection Center (CGMCC), with accession number CGMCC No. 41619. The *Trichoderma viride* strain exhibits a significant inhibitory effect on the growth and infection of *Aspergillus flavus*, with an inhibitory effect superior to 4000 times dilution of tebuconazole. This *Trichoderma viride* strain can produce enzymes that degrade the cell walls of pathogenic fungi. Fungal cell walls are composed of cellulose, glucan, chitin, and glycoproteins. The chitinase and cellulase produced by *Trichoderma viride* can degrade the fungal cell walls, thereby inhibiting the growth, development, and infection of *Aspergillus flavus*. Furthermore, this invention also experimentally demonstrates that *Trichoderma viride* has a highly efficient degradation effect on aflatoxin and fumonisin.
