Problems solved by technology

Although yeast and Sarcina can be used to convert organic carbon compounds in food waste into bioenergy such as ethanol and biogas, but only fully utilize the compounds such as starch and sugar in food waste, while the protein, etc. Utilized to a lesser extent, resulting in low yields of ethanol or biogas
Food waste is directly used to prepare feed. Although the content of nutrients such as protein is high, it cannot be used because of the homology of animal feed.
If a relatively simple microbial strain such as yeast can be used to convert the organic components of kitchen waste into microbial bacterial protein feed, but only starch and sugar in kitchen waste can be used, but cellulose cannot be effectively utilized.

Embodiment 1

[0019] First, 500g of food waste including rice, noodles, meat, eggs, fruits and vegetables collected from the canteen was crushed by a crusher, and then the crushed food waste was put into a glass container and sterilized at 100°C for 20 minutes. , when the temperature drops to 30°C, add 50g of crushed rice husks as a carrier, and at the same time add 50ml of 9 kinds of probiotics including 3 kinds of Bacillus (Bacillus natto, Bacillus coagulans, Bacillus subtilis), 1 photosynthetic A mixed probiotic agent composed of bacteria (Rhodoceus swamp), 2 kinds of yeast (Saccharomyces cerevisiae, Candida), 2 kinds of lactic acid bacteria (Lactic acid bacteria, Lactobacillus acidophilus) and 1 kind of mold (Rhizobia), After fully stirring, put it into a closed stainless steel container for anaerobic fermentation culture. The culture conditions were temperature 25°C, stirring 3 times a day, and samples were taken every day to detect the viable bacteria content of different probiotics. ...

Embodiment 2

[0021] First, 500g of food waste including rice, noodles, meat, eggs, fruits and vegetables collected from the cafeteria was pulverized by a pulverizer, and then the pulverized food waste was put into a glass container and sterilized at 68°C for 30 minutes. , when the temperature drops to 40°C, add 150g of crushed wheat bran as a carrier, and at the same time add 100ml of 9 kinds of probiotics including 3 kinds of Bacillus (Bacillus natto, Bacillus coagulans, Bacillus subtilis), 1 photosynthetic A mixed probiotic agent composed of bacteria (Rhodoceus swamp), 2 kinds of yeast (Saccharomyces cerevisiae, Candida), 2 kinds of lactic acid bacteria (Lactic acid bacteria, Lactobacillus acidophilus) and 1 kind of mold (Rhizobia), After fully stirring, put it into a closed stainless steel container for anaerobic fermentation culture. The culture conditions were 35°C, stirring 3 times a day, and samples were taken every day to detect the viable bacterial content of different probiotics....

Embodiment 3

[0023] First, 500g of food waste including rice, noodles, meat, eggs, fruits and vegetables collected from the cafeteria was pulverized by a pulverizer, and then the pulverized food waste was put into a glass container and sterilized at 82°C for 20 minutes. , when the temperature is lowered to 40 ° C, add 1500 g of crushed starch, rice bran, rice husk, and wheat bran mixture as a carrier, and add 250 ml of 9 kinds of probiotics including 3 kinds of Bacillus (Bacillus natto, Bacillus coagulans) simultaneously. , Bacillus subtilis), 1 type of photosynthetic bacteria (Rhodoconas marsh), 2 types of yeast (Saccharomyces cerevisiae, Candida), 2 types of lactic acid bacteria (Lactic acid bacteria, Lactobacillus acidophilus) and 1 type of mold (Rhizobia ), the mixed probiotics are fully stirred and put into a closed glass container for anaerobic fermentation culture. The culture conditions were temperature 40°C, stirring 3 times a day, and samples were taken every day to detect the vi...

Abstract

The invention relates to a method for producing a microbial ecological agent consisting of bacillus, yeast, lactobacillus, photosynthetic bacteria and mycete by using kitchen garbage, belonging to the field of biotechnology. The method comprises the following steps of: grinding the kitchen garbage containing rice, flour, vegetables, animal and vegetable oil, fruits, meat, bones and the like, and sterilizing the garbage at high temperature; fully mixing the sterilized garbage with carriers and fungicide formed by multiple probiotic bacteria; carrying out anaerobic solid fermentation for one tothree days at 25-40 DEG C, and then airing to obtain high-value microbial ecological agent with the viable bacteria content as high as 50 billion / g. The method provided by the invention has the advantages that different nutrient constituents in the kitchen garbage are fully recycled, the kitchen garbage is efficiently and biologically processed and the high-value microbial ecological agent formedby multiple probiotic bacteria is produced. Besides, the kitchen garbage is fully recycled in the whole process of producing the microbial ecological agent by using the kitchen garbage and any other pollutants requiring further treatment are not generated any more.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular provides a method for producing a micro-ecological preparation composed of bacillus, yeast, lactic acid bacteria, photosynthetic bacteria and mold by using kitchen waste, which can solve the problem of kitchen waste treatment and industrialized production of micro-ecological preparations. Ecological preparations have very important application value and prospects. Background technique [0002] Food waste is mainly divided into food waste and kitchen waste. It is the domestic waste formed by residents in the process of living consumption. It is extremely perishable and deteriorated, emits foul odors, spreads bacteria and viruses, and pollutes the environment. According to reports, Beijing produces about 1,680 tons of kitchen waste every day, while the current daily processing capacity is only about 600 tons. The main components of kitchen waste include food residues such as rice and...
