Bacillus cereus AR156 wettable powders as well as preparation and application thereof

The invention discloses bacillus cereus AR156 (Analytical Reagent156) wettable powders as well as the preparation and application thereof. The bacillus cereus AR156 wettable powders comprise lactose, white carbon black, arabic gum, monopotassium phosphate and bacillus cereus AR156 spores. Bacillus cereus AR156 fermented concentrated solution is taken and mixed with lactose; mixed liquor is added in white carbon black with 325 meshes, and the mixture is stirred fully and is then put on a sterile tray; the mixture is dried for 11 to 13 hours under the temperature ranging from 60 to 70 DEG C, and the final moisture content can reach 20 to 30 percent; dried products are crushed, arabic gum is added during the crushing process, and then crushing is carried out again; and monosodium phosphate is added so as to adjust the pH value until the pH value reaches 7.0, so that the AR156 wettable powders are obtained. The AR156 wettable powders can successfully solve the negative influence that is caused when bacillus ferme
