Method used for preparing probiotic preparations by using vitamin B2 fermentation liquid waste

The present invention discloses a method of using a probiotic formulation prepared Vitamin B2 waste fermentation, comprising the steps of: a) adjusting the pH of the fermentation waste of vitamin B2; 2) was added to the waste probiotic strains for fermentation, when the pH of the fermentation broth or the fermentation broth to 5 cells or spores of the content reaches a certain value, the fermentation was stopped; 3) the fermentation broth was centrifuged to collect the cells or spores; 4) the cells or spores dried in vacuo , that is, too. Vitamin B2 was prepared using the method of the present invention, the waste of the fermentation of probiotics, direct inoculation strains, culture medium formulations are omitted, the high-temperature sterilization process, and shorten the process does not increase emissions, work efficiency, saving production costs; provincial labor and material, energy saving. Probiotics produced by the production method of the present invention, may be added to the feed play disease prevention effect of increasing the efficiency of feed utilization, and can replace the use of antibiotics.
