Under increasing pressure from antibiotic resistance and the growing demand for safe and sustainable livestock and aquaculture systems, Brevibacillus laterosporus<\/em> is emerging as a highly promising biological agent in animal husbandry and aquaculture. Thanks to its superior biological properties, this bacterial strain not only supports growth but also enhances immunity and improves the farming environment.<\/span><\/p>\n

\"\"<\/span><\/p>\n

Overview of Brevibacillus laterosporus<\/em><\/span><\/strong><\/span><\/h3>\n

Brevibacillus laterosporus<\/em> (formerly known as Bacillus laterosporus<\/em>) is a Gram-positive, rod-shaped bacterium with motility and the ability to form spores \u2014 characteristics that allow it to survive well in harsh environments. It grows optimally under aerobic or microaerophilic conditions, within a temperature range of 15\u201337\u00b0C and a pH range of 3 to 7.<\/span><\/p>\n

\"\"<\/span><\/p>\n

Habitat:<\/strong><\/span><\/p>\n

    \n
  • Natural environments:<\/strong> soil, freshwater, dust, organic manure, and decomposing plant matter.<\/span><\/li>\n
  • Biological environments:<\/strong> the intestinal tracts of insects, shrimp, fish, and aquatic farming systems.<\/span><\/li>\n<\/ul>\n

    Key Biological Activities<\/strong><\/span><\/h3>\n
      \n
    • Production of bio-enzymes:<\/strong> such as protease, lipase, and chitinase \u2014 which help break down organic matter, support digestion, and improve water quality.<\/span><\/li>\n
    • Synthesis of natural antimicrobial peptides:<\/strong> capable of effectively inhibiting a wide range of pathogenic bacteria, including Escherichia coli<\/em>, Salmonella<\/em>, Staphylococcus aureus<\/em>, and Vibrio<\/em> spp.<\/span><\/li>\n<\/ul>\n

      Applications of Brevibacillus laterosporus in Aquaculture and Animal Farming<\/strong><\/h3>\n
        \n
      • Promoting Animal Growth<\/strong><\/span><\/li>\n<\/ul>\n

        Brevibacillus laterosporus<\/em> is recognized as an effective probiotic that enhances growth performance and improves nutrient metabolism. By producing digestive enzymes, this bacterium boosts nutrient absorption, lowers feed conversion ratio (FCR), and increases antioxidant activity as well as the function of digestive enzymes.<\/span><\/p>\n

        Recent studies (Darong Yang, 2023; Daode Yu, 2023) have demonstrated that fish and shrimp supplemented with B. laterosporus show significant improvements in growth, digestive efficiency, and oxidative resistance. It also supports healthy development and immunity in poultry and other livestock.<\/span><\/p>\n

          \n
        • Supporting Gut Health<\/strong><\/span><\/li>\n<\/ul>\n

          B.laterosporus<\/em> contributes to gut health by modulating the intestinal microbiota\u2014encouraging the growth of beneficial bacteria (such as <\/span>Lactobacillus<\/em>, <\/span>Ruminococcus<\/em>) while inhibiting harmful species (including <\/span>E. coli<\/em>, <\/span>Pseudomonas<\/em>, <\/span>Salmonella,<\/em> and <\/span>Vibrio<\/em> spp.).<\/span><\/p>\n

          As a result, it enhances digestion, nutrient uptake, and reduces the risk of digestive disorders\u2014factors that are critical for maintaining the overall health and immunity of animals.<\/span><\/p>\n

            \n
          • Inhibiting Pathogenic Bacteria<\/strong><\/span><\/li>\n<\/ul>\n

            This bacterium combats pathogens through multiple mechanisms. It naturally produces antimicrobial compounds\u2014such as peptides and extracellular enzymes (like chitinase and protease)\u2014that suppress or eliminate harmful bacteria such as Vibrio<\/em>, Salmonella<\/em>, and E. coli.<\/em><\/span><\/p>\n

            In addition, B. laterosporus<\/em> competes with pathogens for nutrients and binding sites in the gut, thereby strengthening the animal\u2019s immune defense and lowering the risk of infection\u2014without relying on antibiotics.<\/span><\/p>\n

              \n
            • Controlling Harmful Algae and Improving Water Quality<\/strong><\/span><\/li>\n<\/ul>\n

              Beyond animal health, B. laterosporus<\/em> plays a role in managing pond ecosystems. It helps control harmful blue-green algae (cyanobacteria)\u2014a major factor in declining water quality\u2014by secreting enzymes that break down algal cell walls and releasing metabolites that inhibit algal photosynthesis.<\/span><\/p>\n

              By also competing for nutrients in the water, this bacterium helps limit algal overgrowth and contributes to a cleaner, more stable aquatic environment.<\/span><\/p>\n

              Commercial Application of B. laterosporus<\/span><\/strong><\/h3>\n
