Problems solved by technology

These methods have their own advantages and disadvantages. If landfill disposal is adopted, the production of leachate and biogas will increase, causing secondary pollution.
If incineration is adopted, the average calorific value of the garbage will be reduced, resulting in energy waste, and the high content of NaCl will promote the formation of dioxins and increase the leaching rate of heavy metals in fly ash. , will increase the moisture content of mixed disposal with other wastes, increasing the cost of treatment
Although the composting method can effectively treat catering waste, it does not make full use of the nutrients in the catering waste, resulting in a waste of resources.
[0005] To sum up, the mode of transporting catering waste directly to the farm to feed pigs or mixed with ordinary waste into landfill can no longer meet the requirements of environment, sanitation and health

Embodiment 1

[0031] A method for producing high-protein feed by utilizing multi-strain joint solid-state fermentation of catering waste, comprising the following steps:

[0032] 1. Preparation of composite bacterial solution

[0033] (1) Select the following microbial strains as the bacterial source: Geotrichum candidum, Yarrowia lipolytica, Phanerochaete chrysosporium.

[0034] (2) The preparation process of the composite bacterial solution is as follows:

[0035] Slope culture → liquid strain → liquid primary seed (shake flask) cultivation → liquid secondary seed cultivation → determination of bacterial count → mixing of bacterial strains in proportion → fermentation liquid

[0036] Concrete preparation process is as follows:

[0037] 1) Slant strain culture: Geotrichum candidum and Yarrowia lipolytica slant culture adopts a culture medium containing 0.8% peptone, 1.0% glucose, 0.3% beef extract, 2.0% agar, and the rest is distilled water at pH 7.2 to 7.4; Phanerochaete slant culture ...

Embodiment 2

[0044]1. The preparation of catering waste residue fermentation bacteria liquid and the treatment of catering waste residues are the same as in Example 1. The number of live bacteria in each fermentation bacteria liquid is measured. : 0.6: 0.6 were mixed to make a compound fermentation broth.

[0045] 2. Preliminary screening of catering waste residue, picking out non-fermentable materials such as plastics, crushing and mixing the bone, and measuring the initial waste residue composition. The pH value is about 6.4, the salt content is 1% to 2%, and the oil content is about 10%. The crude fiber content is 8% to 15%, the crude protein content is 6% to 12%, and the soluble protein content is about 1.09mg / g; adjust the pH value between 6 and 7, and the moisture content between 65% and 70%. Add mixed strains at 30°C, the inoculation ratio is 15%-20%, solid-state fermentation for 78-84 hours, dry and sterilize, and it can be made into pH value 6-7, salt content 1%-2%, oil content 2...

Embodiment 3

[0047] 1. The preparation of catering waste residue fermentation bacteria liquid and the treatment of catering waste residues are the same as in Example 1. The number of live bacteria in each fermentation bacteria liquid is measured. : 1: 0.6 for mixing to make a compound fermentation broth.

[0048] 2. Preliminary screening of catering waste residue, picking out non-fermentable materials such as plastics, crushing and mixing the bone, and measuring the initial waste residue composition. The pH value is about 6.4, the salt content is 1% to 2%, and the oil content is about 10%. The crude fiber content is 8% to 15%, the crude protein content is 6% to 12%, and the soluble protein content is about 1.09mg / g; adjust the pH value between 6 and 7, and the moisture content between 65% and 70%. Add mixed strains at 30°C, the inoculation ratio is 15%-20%, solid-state fermentation for 78-84 hours, dry and sterilize, and it can be made into pH value 6-7, salt content 1%-2%, oil content 2%...

Abstract

The invention discloses a compound zymophyte liquid, which comprises geotrichum candidum, lipolytic yarrow yeast and Phanerochaete chrysosporium. The invention further discloses a method for preparing the compound zymophyte and a method for producing feed from restaurant waste residue through solid-state fermentation by using the compound zymophyte liquid. By using the technique of combining a plurality of strains with solid-state fermentation, protein feed can produced, thereby overcoming the disadvantages in prior art, and achieving the effect of improving protein content in a product, reducing grease content and cellulose content in the product, and improving the effective utilization ratio of the restaurant waste residue.

Description

technical field [0001] The invention relates to the treatment of catering waste, in particular to a method for fermenting and producing high-protein feed by using catering waste, and a compound fermentation bacterium for fermentation. Background technique [0002] With the rapid development of my country's animal husbandry, the demand for feed has higher requirements in terms of quantity and variety. It is the development trend of feed industry to vigorously develop feed with high nutritional value and low production cost. [0003] As we all know, my country is a populous country, and China's unique eating habits have caused a lot of waste in my country's catering industry, and catering waste has become a huge bioavailable resource. At present, the utilization rate of catering waste is very low, and the phenomenon of waste is very serious. Most of them are mixed with domestic waste and incinerated or buried, causing air and soil pollution. In some places, they are piled up...
