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

Abstract

The invention discloses a method used for preparing probiotic preparations by using vitamin B2 fermentation liquid waste. The method comprises following step: 1) the pH value of the vitamin B2 fermentation liquid waste is adjusted; 2) probiotic strain is added into the vitamin B2 fermentation liquid waste for fermentation, and fermentation is stopped when the pH value of the fermentation broth reaches 5 or the amount of probiotic or spore reaches a certain value; 3)the fermentation broth is subjected to centrifugal separation so as to collect probiotic or spore; and 4) probiotic or spore is subjected to vacuum drying so as to obtain the finished products. According to the method used for preparing probiotic preparations by using vitamin B2 fermentation liquid waste, probiotic strain is inoculated directly, processes of preparation and high-temperature disinfection of medium are avoided, technological process is shortened, discharge is not increased, work efficiency is increased, production cost is reduced, labor and raw materials are reduced, and energy saving and emission reduction are realized. The probiotic preparations prepared by using the method can be added into forage so as to realize disease prevention and treatment, and increase utilization rate of forage; and is capable of taking place of antibiotic.

Description

technical field [0001] The invention belongs to the technical field of fermentation waste liquid treatment, in particular to a method of using vitamin B 2 A method for preparing a probiotic preparation from fermentation waste liquid. Background technique [0002] Vitamin B 2 Riboflavin, also known as riboflavin, is one of the indispensable vitamins in biological life activities. It is closely related to the metabolism of carbohydrates, fats and amino acids in the human body, and plays an extremely important role in the growth and development of organisms. Vitamin B 2 Fermentation waste liquid refers to vitamin B 2 During production, vitamin B 2 Residue waste after distillation. The waste liquid has a solid content of about 5%, contains a large amount of nutrients such as sugar, protein, ammonia nitrogen, etc., which are often needed for the growth of microorganisms, and is a sterile liquid. [0003] In the prior art, vitamin B 2 The treatment method of the fermentatio...
