“…Some beneficial bacteria ( Pseudomonas and Microbacterium ) related to the control of crop diseases are significantly positively correlated with B. laterosporus BL12 and significantly negatively correlated with the disease index, which may cooperate with BL12 to control PCS [ 33 ]. The biocontrol efficiency of B. laterosporus SN19-1 against bacterial leaf blight caused by Xanthomonas was 90.92% [ 34 ]. The inhibitory effect of B. laterosporus B4 on Acidovorax avenae subsp.…”

Brevibacillus laterosporus (B. laterosporus) is widely distributed in nature and demonstrates significant potential for applications in biological control, environmental protection, agricultural production, and clinical medicine. This review provides a comprehensive overview of the applications of B. laterosporus in crop cultivation and animal feeding, as well as an examination of the antimicrobial peptides produced by B. laterosporus and their antibacterial mechanisms. B. laterosporus enhances crop cultivation by secreting hydrolases to improve nutrient absorption capabilities, synthesizing hormones to promote crop growth, and producing proteins to inhibit the reproduction of harmful organisms. B. laterosporus has been used to improve animal production by regulating the structure of the intestinal microbiota and inhibiting the growth of pathogenic bacteria through the secretion of various antimicrobial peptides. The bactericidal activity of Brevilaterins secreted by B. laterosporus is attributed to their ability to bind to lipopolysaccharide/lipid II molecules on the cell membrane, thereby altering permeability. Brevilaterins also inhibit bacterial reproduction by affecting relevant gene pathways in the cell membranes of pathogenic bacteria. These pathways include ATP synthesis, peptidoglycan biosynthesis, membrane transport, and cellular metabolism. In conclusion, B. laterosporus exhibits substantial potential as a probiotic activity in crop and animal production. However, applications of B. laterosporus in animal production could be improved, necessitating further research to elucidate the underlying probiotic mechanisms.
