Problems solved by technology

[0003] 1. A stable micro-ecological system should be formed among the strains of the compound bacterial agent, and it can metabolize various substrates with comprehensive functions. Because the types of kitchen waste are complex, including sugar, protein, oil, cellulose, etc., if the bacteria The single function of the agent often has a narrow scope of application, and the treatment effect is not ideal
[0004] 2. The compound bacterial agent must be able to withstand high salt content, because the salt will accumulate during the process of food waste decomposing and drying in the processing cabin, and the salt content of the material will usually reach 3% to 5%. If it cannot tolerate high-salt bacteria The agent cannot survive and reproduce, and the treatment effect is not ideal.
[0005] 3. The compound bacterial agent must be able to withstand high temperature, because the ambient temperature in the processing cabin of food waste will reach 60 ℃ ~ 70 ℃, so as to kill harmful bacteria and insect eggs. If the bacterial agent cannot tolerate high temperature, it will not be able to survive and Breeding, unsatisfactory treatment effect

Abstract

The invention discloses a preparation method of a high temperature-resistant and salt-resistant kitchen waste decomposing compound bacteria agent. The preparation method comprises the following steps:respectively performing seed culture on streptomycete, bacillus subtilis, bacillus amyloliquefaciens and saccharomyces cerevisiae, so that a streptomycete mycelium pellet suspension, a bacillus subtilis bacteria solution, a bacillus amyloliquefaciens bacteria solution and a saccharomyces cerevisiae bacteria solution are respectively and correspondingly obtained; inoculating the streptomycete mycelium pellet suspension to a solid fermentation material for culture to obtain solid decomposing bacteria; mixing the other three bacteria solutions to obtain a compound bacteria solution; stirring anduniformly mixing the compound bacteria solution and the solid decomposing bacteria according to the proportion of 9-11 ml / 100g, then drying at a low temperature, and finally adding an enzyme preparation for mixing to obtain the decomposing compound bacteria agent. The compound bacteria agent is used for decomposing kitchen wastes.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a preparation method and application of a high-temperature and salt-resistant kitchen decomposing compound bacterial agent. Background technique [0002] Organic material decomposing bacteria agents, especially those used for food waste treatment, need to overcome the following problems: [0003] 1. A stable micro-ecological system should be formed among the strains of the compound bacterial agent, and it can metabolize various substrates with comprehensive functions. Because the types of kitchen waste are complex, including sugar, protein, oil, cellulose, etc., if the bacteria The single function of the agent often has a narrow scope of application, and the treatment effect is not ideal. [0004] 2. The compound bacterial agent must be able to withstand high salt content, because the salt will accumulate during the process of food waste decomposing and drying in the processing cabi...
