The role of Bacillus subtilis in aquaculture

Bacillus subtilis plays various important roles in aquaculture. Here is a detailed introduction:

枯草芽孢杆菌在水产养殖中发挥着多种重要作用。下面详细介绍一下:

Bacillus subtilis can rapidly reproduce and colonize on the surface of animal tissues or within plants, effectively preventing the proliferation of pathogenic microorganisms such as Vibrio and Escherichia coli.枯草芽孢杆菌能在动物组织表面或植物内部迅速繁殖定植，有效阻止弧菌、大肠杆菌等病原微生物的增殖。

Bacillus subtilis has strong decomposition ability, which can decompose organic matter, ammonia nitrogen, nitrite, etc., improving substrate and water quality.枯草芽孢杆菌分解能力强，能分解有机物、氨氮、亚硝酸盐等，改善基质和水质。

Bacillus subtilis can inhibit the proliferation of harmful algae, such as blue-green algae.枯草芽孢杆菌可以抑制有害藻类的繁殖，如蓝绿藻。

Bacillus subtilis can secrete extracellular enzymes such as protease, lipase, and amylase, which can promote the degradation of nutrients in feed and improve the absorption and utilization rate of feed by aquatic animals.枯草芽孢杆菌能分泌蛋白酶、脂肪酶、淀粉酶等胞外酶，促进饲料中营养物质的降解，提高水生动物对饲料的吸收利用率。

Bacillus subtilis can produce various nutrients, such as vitamins, amino acids, organic acids, and growth promoting factors, which participate in the metabolism of aquatic animals and improve their growth rate.枯草芽孢杆菌能产生多种营养物质，如维生素、氨基酸、有机酸、生长促进因子等，参与水生动物的代谢，提高其生长速度。

Bacillus subtilis can stimulate the development of immune organs in aquatic animals, enhance the body's immunity, and reduce the occurrence of diseases.枯草芽孢杆菌能刺激水生动物免疫器官的发育，增强机体免疫力，减少疾病的发生。

Bacillus subtilis can also decompose residual bait, feces, organic matter, etc. in the pond, and has the function of cleaning small particles of garbage in water.枯草芽孢杆菌还能分解池塘中残留的饵料、粪便、有机物等，并具有清洗水中小颗粒垃圾的功能。

In addition, Bacillus subtilis is harmless to humans and animals, pollution-free to the environment, and helps to improve economic benefits.此外，枯草芽孢杆菌对人畜无害，对环境无污染，有助于提高经济效益。
