The effect of Bacillus subtilis on water purification 水净化枯草芽孢杆菌对水净化的影响水净化枯草芽孢杆菌在水净化中的作用

    Bacillus subtilis can serve as a microbial regulator, improving water quality 改善水质 改善水质, inhibiting harmful microorganisms, and creating a favorable aquatic ecological environment. The water bodies of aquaculture, due to long-term high-density breeding of animals, accumulate a large amount of pollutants such as bait residues, animal debris, and fecal deposits, which can easily cause water quality deterioration and endanger the health of breeding animals, and even reduce production and cause losses, posing a huge threat to the sustainable development of aquaculture industry. Bacillus subtilis can colonize in water and form dominant bacterial communities through nutritional or spatial competition, inhibiting the growth and reproduction of harmful pathogens (such as Vibrio, Escherichia coli) and other harmful microorganisms in water, thereby changing the number and structure of microorganisms in water and sediment, and effectively preventing diseases caused by water quality deterioration in aquatic animals. Meanwhile, Bacillus subtilis, as a strain capable of secreting extracellular enzymes, secretes a variety of enzymes that can effectively decompose organic matter in water and improve water quality.枯草芽孢杆菌可以作为微生物调节剂，改善水质，抑制有害微生物，创造良好的水生生态环境。养殖水体由于长期高密度养殖动物，积累了大量饵料残留物、动物残骸、粪便沉积物等污染物，容易造成水质恶化，危害养殖动物健康，甚至减产造成损失，对水产养殖业的可持续发展构成巨大威胁。枯草芽孢杆菌可通过营养或空间竞争在水中定植，形成优势菌群，抑制水中有害病原体(如弧菌、大肠杆菌)和其他有害微生物的生长繁殖，从而改变水体和沉积物中微生物的数量和结构，有效预防水生动物因水质恶化而引起的疾病。同时，枯草芽孢杆菌作为一种能够分泌胞外酶的菌株，分泌多种酶，能有效分解水中有机物，改善水质。

    For example, the active substances produced by Bacillus subtilis, such as chitinase, protease, and lipase, can decompose organic matter in water and degrade nutrients in animal feed. This not only allows animals to fully absorb and utilize nutrients in feed, but also greatly improves water quality; Bacillus subtilis can also regulate the pH value of aquaculture water. 如枯草芽孢杆菌产生的几丁质酶、蛋白酶、脂肪酶等活性物质，可以分解水中的有机物，降解动物饲料中的营养物质。这不仅能让动物充分吸收和利用饲料中的营养物质，还能大大改善水质;枯草芽孢杆菌还能调节养殖水体的pH值。如枯草芽孢杆菌产生的几丁质酶、蛋白酶、脂肪酶等活性物质，可以分解水中的有机物，降解动物饲料中的营养物质。这不仅能让动物充分吸收和利用饲料中的营养物质，还能大大改善水质;枯草芽孢杆菌还能调节养殖水体的pH值。

    Bacillus subtilis is also widely used in wastewater treatment 废水处理 废水处理, biological fertilizer fermentation, or fermentation bed production, and is a multifunctional microorganism.枯草芽孢杆菌还广泛应用于废水处理、生物肥料发酵或发酵床生产，是一种多功能微生物。枯草芽孢杆菌还广泛应用于废水处理、生物肥料发酵或发酵床生产，是一种多功能微生物。
