Concentrated probiotics preparation and production thereof

Abstract

An enrichment probiotics pharmaceutics and its preparation method are provided in the invention. The medium is made up of the phosphate, the MgCl2, the CaCl2, the sodium propionate, the distilled water, the proper growth factor and the microelement. And its pH is adjusted to the proper. Then the actived strain is added into the medium to culture. The flocculating agent is made up of the chitosan and the alum. The protecting agent is made up of the dried skim milk, the brown sugar, the glycerol, the distilled water. The weight ration of the probiotics pharmaceutics is probiotics liquid 800-1200 portion, flocculating agent 1-25 portion, the protecting agent 80-120 portion. It can be used to the aquiculture, the agricultural plant, the effluent treatment and the fancy fish breeding. It can inhibit or kill the breeding of the bacillus and the fungus.

Description

Technical field

[0001] The invention relates to a concentrated probiotic preparation and a preparation method thereof. Background technique

[0002] Most of the probiotic preparations currently on the market, especially those used in aquaculture, are relatively dilute liquid preparations. During the preparation process, the medium needs to be sterilized at high temperature and the supernatant should be discarded by a high-speed centrifuge. . The production cost of this preparation method is high, and the thallus after high-speed centrifugation will become fragile and cause death. The shelf life is short, and long-term storage will cause loss of finished products due to the reproduction of residual bacteria and their spores. This product is also not suitable for long-distance transportation, especially cannot inhibit and kill the effect of bacillus propagule and mold produced due to pollution during long-term storage and production.
