Bacillus subtilis wettable powder and preparation process thereof

Abstract

The invention discloses bacillus subtilis wettable powder. Every 1000g of the wettable powder is prepared from the following raw materials: 800g of bacillus subtilis, 450g of distilled water, 250g ofglucose, 150g of peptone, 5g of sodium chloride, 200g of a beef extract and 20g of agar. The bacillus subtilis wettable powder has the beneficial effects that due to addition of the agar and the peptone in production raw materials of the wettable powder, cultured bacillus subtilis can be subjected to solidification protection operation of the agar in the bacillus subtilis culture process, and growth of the peptone can be accelerated after being put into a culture dish; a mixing machine used in a preparation process disclosed by the invention is provided with a lifting clamping ring, a lower bucket base is driven to move upwards or downwards on the inner side of a mixing bucket, an internal depth of the mixing bucket can be adjusted, and then the mixing bucket can be randomly adjusted and operated according to numbers of raw materials to be processed; meanwhile, together with a rotating bottom tube at the bottom of the lower bucket base, raw materials of the mixing bucket can be flexibly conveyed and operated, and the application range of the mixing bucket can be widened.

Description

technical field [0001] The invention belongs to the technical field of Bacillus subtilis, in particular to a wettable powder, more particularly to a Bacillus subtilis wettable powder and a preparation process thereof. Background technique [0002] Bacillus subtilis is a gram-positive bacterium belonging to the genus Bacillus that is uniformly colored, has no capsule, is pericytoflagellated, and can move. Slightly biased, the cells do not expand after spore formation. The surface of the colony is rough and opaque, dirty white or yellowish. When growing in liquid medium, it often forms wrinkle. Aerobic bacteria can use protein, various sugars and starches to decompose tryptophan to form indole. It is widely used in the bacterium, and the research on the synthetic pathway and regulation mechanism of purine nucleotides in this bacteria is clear. Widely distributed in soil and decaying organic matter; [0003] The existing preparation technology of Bacillus subtilis wettable p...

AI Technical Summary

Problems solved by technology

[0003] The existing Bacillus subtilis wettable powder preparation process has certain disadvantages in the operation process. The traditional Bacillus subtilis adopts the traditional formula, which increases the time required for the cultivation of Bacillus subtilis. At the same time, the Bacillus subtilis wettable powder is being processed During the mixing operation, the use of the traditional mixer is not flexible enough. The traditional mixer has an integral fixed structure, which reduces its scope of application. At the same time, the traditional mixer only has a single-weight mixing and crushing structure, which makes the mixing of raw materials not uniform enough. , it is impossible to adjust the feeding speed of raw materials and the output angle of raw materials, which will bring certain adverse effects to users
