Abstract

The invention discloses a process for producing biological packing bacterium bacillus natto. The process comprises the following steps: (1) preparing a seed culture medium; (2) culturing seeds; (3) preparing a fermenting culture medium from glucose, bran, soybean meal, NaCl, stachyose, monopotassium phosphate, calcium chloride and plant compound fermented extract with pH value of 7.5; and (4) culturing by fermentation, namely culturing for 18-20 hours at low temperature of 32-35 DEG C with the inoculum size of 4 percent (v / v) and liquid measure of 75 percent and sufficiently supplying oxygen during the quick fermenting stage; adding glucose twice in the quick fermenting stage, and controlling the final concentration is not higher than 20 percent; and adding ailanthus ketone, reducing temperature to 10-15 DEG C, and performing anaerobic fermentation for 2-3 hours to improve the spore rate. The process has the advantages of short time consumption, low cost and high spore rate, has a great economic value, and has wide market prospect in the field of agriculture breeding.

Description

technical field [0001] The invention relates to a production process of biological bedding bacterium Bacillus natto, belonging to the field of microorganism cultivation. Background technique [0002] Fermentation bed pig raising is the application of special flora preparations containing one or more beneficial microorganisms such as Bacillus natto, Bacillus subtilis, Actinobacillus, lactic acid bacteria, etc., mixed with sawdust, rice husk, straw and other litter, and laid into a fermentation bed , Beneficial bacteria reproduce in large numbers through aerobic and anaerobic fermentation to form dominant flora. The pigs raised on the fermentation bed excrete the feces and urine into the fermentation bed, and through pig arches or manual turning, the excrement and litter are fully stirred and mixed evenly, and the feces and urine are quickly degraded and digested by beneficial bacteria in the litter. Pollution, so as to achieve the goal of zero discharge of feces and urine, e...
