The invention relates to the technical field of nano engineering and probiotics, in particular to a bacteriostatic composition and a fungicide, a veterinary drug and a feed containing the bacteriostatic composition. The invention provides a bacteriostatic composition prepared by simultaneously mixing nano iron sulfide and lactobacillus, which can protect the intestinal colonization ability of lactobacillus and other beneficial bacteria, so that the nano iron sulfide promotes bacterial ferroptosis of pathogenic bacteria in the intestinal tract. The nano iron sulfide and the lactobacillus synergistically inhibit the growth of pathogenic bacteria such as escherichia coli, salmonella typhimurium and staphylococcus aureus in vitro and in intestinal tracts, have no adverse effect on beneficial bacteria and host intestinal epithelial cells, and are beneficial to intestinal health. The invention provides a natural and efficient application mode, and has very high conversion value.

The invention discloses pediococcus pentosaceus TRM54998 with broad-spectrum antibacterial activity and application of the pediococcus pentosaceus TRM54998, and belongs to the field of microorganisms. The strain is preserved in the China Center for Type Culture Collection (CCTCC) on June 04, 2024, and the preservation number is CCTCC NO: M 20241142. It is proved that the strain has good acid resistance and bile salt resistance and can grow in the environment with the bovine bile salt concentration being 0.1-0.2% (w/v) or in the pH value range being 3-7; the fermentation supernatant has an inhibition effect on nine pathogenic bacteria such as salmonella and the like, and the antibacterial effect is stable; meanwhile, experiments prove that the pediococcus pentosaceus TRM54998 has no wide drug resistance, can relieve the problems of aggravated drug resistance, damage to microbial ecological balance and the like caused by antibiotic abuse, provides a strain resource for preparing a biological bacteriostatic agent or an intestinal probiotic agent, and has a wide application prospect.
