Bacillus belongs to gram-positive bacteria, aerobic, can produce spores; It is a kind of heterotrophic bacteria with high activity of digestive enzyme system, high temperature resistance and stress resistance, and strong resistance to external harmful factors. Widely distributed, in the soil, fresh sea water, air and animal intestines are abundant; It has the characteristics of fast reproduction speed, strong vitality and large volume.
Application of Bacillus in aquaculture
Improve purified water quality
Bacillus secrete a large number of high activity amylase, protease and lipase in the process of reproduction, which can quickly degrade the residual baits, feces and other organic matter, thus reducing COD and purifying water. Bacillus can also directly use nitrite and ammonia nitrogen in water to decompose carbon, nitrogen and sulfur compounds, so as to improve aquaculture water quality.
Inhibits bacteria and kills pathogenic bacteria
Bacillus subtilis in metabolic processes to produce a antibiotics with inhibiting or killing microorganisms (bacillus subtilis), can by splashing and internal and inhibit or kill harmful bacteria, water and organisms competitive promote the growth of beneficial bacteria breeding, and to control the breeding of harmful bacteria in water and biology, so as to realize the purpose of prevention and treatment of fish diseases.
Improve feed conversion rate
Bacillus can produce a variety of highly active enzymes, such as amylase, protease and lipase, which work together with digestive enzymes in the digestive tract to improve feed utilization rate and promote growth.
Promote animal growth, improve animal immunity
The growth and reproduction of Bacillus in animal intestines can produce a variety of nutrients such as vitamins and growth promoting factors, which participate in the metabolism of cultured animals and improve their disease resistance. It can stimulate the growth and development of fish immune organs and improve the immunity of fish.
The use of bacillus
Aerobic activation with sugar and water
Dissolve the carbon source (brown sugar, molasses, etc.) in water, add Bacillus and mix well, wake up the dormant Bacillus and sprinkle it for use after 3-4h.
Mixed materials are used for fermentation
When the activated Bacillus liquid and lactic acid bacteria liquid were sealed overnight in 1/4 of the feed mixture, the gastrointestinal function of fish and shrimps could be improved, the feed utilization rate could be increased and the growth could be promoted.
