Embodiment 1

[0028] Collect fresh kitchen waste, separate solid and liquid to obtain solid waste and liquid waste, and pick out impurities such as broken glass and plastic in solid waste.

[0029] 1. Preparation of Candida tropicalis bacterial solution: Candida tropicalis (purchased from China Center for Type Culture Collection (CCTCC), its preservation number: CCTCC AY92045) was cultured from Candida tropicalis slant Pick a loop from the base and inoculate it into the liquid Candida seed medium, at 28°C, 150rpm, shake and culture for 24h, and check the purity by microscopy. Then the inoculum of 3% (v / v) was inserted into the fermenter filled with Candida seed medium, the temperature was 28°C, the stirring speed was 250rpm, and the ventilation rate was 3L / (L·min) , the fermentation time is 24 hours to obtain Candida tropicalis bacteria liquid, the Candida slant medium contains glucose 5g / L, peptone 2g / L, yeast extract 1g / L, sodium chloride 0.5g / L, agar 20g / L, the balance is water, pH is 7...

[0044] Collect fresh kitchen waste, separate solid and liquid to obtain solid waste and liquid waste, and pick out impurities such as broken glass and plastic in the solid waste.

[0045] 1. Preparation of Candida tropicalis bacterial liquid: Pick a ring of Candida tropicalis from the Candida slant medium and inoculate it into the liquid Candida seed medium, and inoculate at 30°C , 150rpm, shake culture for 48h, microscopically check the purity, the strain is in the logarithmic growth phase, stop the culture, and obtain the first-class strain of Candida tropicalis; In the fermenter of Trichosanthes seed culture medium, the temperature is 30°C, the stirring speed is 200rpm, the ventilation rate is 2L / (L·min), and the fermentation time is 24 hours, to obtain the Candida tropicalis bacteria liquid, the Candida tropicalis Bacteria slant medium contains glucose 5g / L, peptone 2g / L, yeast extract 1g / L, sodium chloride 0.5g / L, agar 20g / L, the balance is water, pH is 6.5, sterilization...

Embodiment 3

[0056] Collect fresh kitchen waste, separate solid and liquid to obtain solid waste and liquid waste, and pick out impurities such as broken glass and plastic in the solid waste.

[0057] 1. Preparation of Candida tropicalis bacterial liquid: Pick a ring of Candida tropicalis from the Candida slant medium and inoculate it into the liquid Candida seed medium, and incubate at 37°C , 200rpm, shake culture for 12h, microscopically check the purity, the strain is in the logarithmic growth phase, stop the culture, and obtain the first-class strain of Candida tropicalis; In the fermenter of the trichotillomyces seed medium, the temperature is 35°C, the stirring speed is 300rpm, the ventilation rate is 4L / (L·min), and the fermentation time is 72 hours, to obtain the Candida tropicalis liquid, the Candida tropicalis The slant medium contains glucose 5g / L, peptone 2g / L, yeast extract 1g / L, sodium chloride 0.5g / L, agar 20g / L, the balance is water, pH is 7.5, sterilization conditions: ste...

Abstract

The invention discloses a method for producing a functional microorganism organic fertilizer by using food residue. According to the invention, the food residue is subjected to solid-liquid separation, and solid residue and liquid residue are respectively recycled, therefore, the cost for purchasing a culture medium when a strain is cultured is saved, the food residue is fully and maximally utilized without generating secondary pollution. For first-time fermentation of a fermentation substrate, inoculation of a large quantity of beneficial bacteria is adopted, and the beneficial bacteria are immediately propagated in short time and dominate in the fermentation substrate to play a role of sterilizing, therefore, the energy consumption and input required by sterilization are reduced, and the time of decomposing the substrate thoroughly is shortened. During secondary fermentation, a special functional strain is selected and applied to play roles in preventing, resisting and treating diseases of plants, and therefore the additional value of a product is fully developed. The method is used for reasonably and thoroughly treating the food residue and producing the functional microorganism fertilizer with strong practicability and high value by using the functional strain, maximizes the use values of food residue and is environment-friendly.

Description

Technical field: [0001] The invention belongs to the field of microbial fermentation, and in particular relates to a production method for preparing functional microbial organic fertilizer by using food and beverage waste. Background technique: [0002] Catering waste, also known as kitchen waste, refers to the waste generated in the process of food processing in the kitchen and the leftover food on the table. It is a kind of domestic waste in the process of living consumption by residents. Restaurants each account for 50%. Mainly include: rice and flour food residues, vegetables, vegetable oils, animal oils, meat bones, fish bones, etc. From the chemical composition, there are starch, cellulose, protein, lipids and inorganic salts. Among them, organic components are the main components, containing a large amount of starch and cellulose. The content of NaCl in inorganic salts is relatively high, and it also contains a certain amount of trace elements such as calcium, magne...
