Abstract

The invention provides a preparation method for composite bacillus microcapsule preparations. The method comprises the steps that bacillus subtilis YB-1 CGMCC No.5116 bacterial suspension, bacillus cereus YB-2 CGMCC No.5117 bacterial suspension and bacillus flexus XH-1 CGMCC No.5115 bacterial suspension are mixed and fermented to obtain fermentation products; protective agents and bacteria carrier fluid are added into the fermentation products, the mixture is fully shaken and sprayed in CaCl2 curing liquid to conduct curing, after curing is conducted, filtering, low temperature freeze drying, adsorption carrier absorbing and drying are conducted in sequence, and the composite bacillus microcapsule preparations are obtained. The composite bacillus microcapsule preparations have the advantages that the microbial content is high, intimidation of high temperature, oxygen, acid environment on composite bacilli can be effectively avoided, and the application effect of the composite bacilli in the aquatic animal breeding process is greatly improved.

Description

technical field [0001] The invention relates to the technical field of microbial preparations for aquatic animals, in particular to a preparation method of a compound bacillus microcapsule preparation. Background technique [0002] Aquatic micro-ecological preparations are live bacterial preparations formed by using beneficial microorganisms in aquatic animals or in aquaculture water through special processing techniques. It can be used to regulate the balance of flora in the intestinal tract of animals and enhance the nutrition and immunity of aquatic animals. In aquaculture, commonly used probiotics mainly include Bacillus, photosynthetic bacteria, lactic acid bacteria, yeast and nitrifying bacteria. Bacillus has strong stress resistance, high temperature resistance, acid and alkali resistance, extrusion resistance, can be processed into pellet feed without changing activity, can regulate intestinal flora, maintain micro-ecological balance, and inhibit Vibrio in intestina...
