Food waste fermentation composite bacteria and preparation method thereof

Abstract

The invention discloses food waste fermentation composite bacteria and a preparation method thereof, and the preparation method comprises the following steps: respectively performing high-density culture on strains of trichoderma viride, bacillus subtilis, bread mold, photosynthetic bacteria, saccharomyces cerevisiae and bacillus licheniformis, performing dehydration and drying on various types of monoxenie obtained by high-density culture to prepare hypopus microbial dry powder, and then mixing according to the weight ratio of 20-45 parts of the trichoderma viride, 10-15 parts of the bacillus subtilis, 20-30 parts of the bread mold, 5-10 parts of photosynthetic bacteria, 7-15 parts of saccharomyces cerevisiae and 10-15 parts of bacillus licheniformis to get the food waste fermentation composite bacteria. The food waste fermentation composite bacteria are good in fermentation effect for treating food waste and significant in deodorization effect, and the food waste after using the composite bacteria for fermentation treatment can be used as an organic fertilizer, thereby changing the waste into valuable, avoiding polluting a water source, the land and the air and avoiding harming human bodies.

Description

technical field [0001] The invention relates to the technical field of bioengineering microbial fermentation, in particular to a composite food waste fermentation bacterium and a preparation method thereof. Background technique [0002] Compared with ordinary garbage, food waste has the following characteristics: 1. Food waste has high oil content and high viscosity; 2. Food waste has high salt content, and microorganisms are not easy to survive; 3. Food waste is piled up densely and is not easy to ventilate; 4. , High moisture content; 5, High organic matter content. Therefore, food waste is difficult to ferment, and there is no successful large-scale use of food waste treatment products in China. [0003] At present, the treatment of food waste mainly includes feeding livestock, oil extraction, incineration, landfill, etc., but the above treatment methods have the following hazards: 1. Food waste is directly fed to chickens, pigs and other livestock, It is easy to cause ...

Therefore, food waste is difficult to ferment, and there is no large-scale use of food waste treatment products in China

[0003] At present, the treatment of food waste mainly includes feeding livestock, oil extraction, incineration, landfill, etc., but the above treatment methods have the following hazards: 1. Food waste is directly fed to chickens, pigs and other livestock, It is easy to cause animal diseases, and the formation of a biological chain will eventually affect human health. Now the country has banned food waste from feeding livestock; 2. The oil extracted from food waste, that is, waste oil, is very likely to Flowing to the dining table will eventually affect human health. Now the country has attached great importance to this issue, and the relevant national standards are also being formulated; 3. Put it into the garbage disposal site as ordinary garbage, and adopt conventional incineration, landfill and other treatment methods, but the kitchen The moisture content of the garbage can reach more than 70wt%, and the organic matter content can reach as high as 90wt% (dry basis), so the garbage dump has a strong smell and the sewage is everywhere, polluting the land, air and water sources

Moreover, the use of treatment methods such as burning, landfilling or feeding animals will cause water, land, and air pollution, which will cause harm to the human body
