Method for producing probiotics by utilizing lignocellulose hydrolysate

The invention discloses application of lignocellulose hydrolysate for increasing the spore forming rate of bacillus coagulans and/or the spore concentration, and a method for producing bacillus coagulans by utilizing the lignocellulose hydrolysate. Particularly, agriculture and forestry biomass raw materials are hydrolyzed at 105-130 DEG C by utilizing 1-4% of H2SO4; after being detoxified through Ca(OH)2, the obtained lignocellulose hydrolysate as a carbon source is added into a bacillus coagulans fermentation culture medium according to a certain proportion; therefore, the spore forming rate and the spore concentration can be obviously increased; the spore concentration can be up to 2.5*10 cfu/mL maximally; and the spore concentration is 5-10 times of that at home and abroad currently. The spore yield of probiotics, namely bacillus coagulans, can be obviously increased by utilizing agriculture and forestry lignocellulose raw materials; raw materials are easy to obtain and low in cost; the production process is simple; and the method has better popularization and application value.
