Description

technical field

[0001] The invention belongs to the technical field of microbial fermentation, and in particular relates to a compound bacterial agent used for recycling vegetable residues and its preparation method and application. Background technique

[0002] At present, a large number of vegetable residues are produced every day in vegetable greenhouses, farmers' markets, etc. Greenhouse growers and vendors mostly pile them up in the fields, let them rot, or throw them into trash cans, and finally transport them to garbage dumps for landfill landfill. Improper disposal of vegetable residues has caused serious pollution to the rural and urban environments. Due to the variety, quantity and weight of vegetable residues produced every day, the cost of external transportation and landfill processing is increased.

[0003] In fact, vegetable residues contain a certain amount of carbon, nitrogen, phosphorus, potassium, calcium and other elements, and are rich in organic matte...

Examples

preparation example Construction

[0030] A method for preparing a compound microbial agent for recycling vegetable residues according to an embodiment of the present invention comprises the following steps:

[0031] (1) Inoculate Bacillus bh1, Bacillus bh2, Bacillus bh3, and Bacillus cereus on 150ml LB liquid medium respectively, at a temperature of 35-37°C, at a speed of 130-150rpm, and cultivate for 40-50 hours to obtain Bacillus bh1 , Bacillus bh2, Bacillus bh3, Bacillus cereus suspension;

[0032] (2) Inoculate Gordonella on 150ml of beef extract-peptone liquid culture medium, at a temperature of 30° C., at a speed of 100 to 120 rpm, and cultivate for 60 to 70 hours to obtain the Gordonella bacterium liquid;

[0033] (3) Take the same volume of the above five bacterial agents and mix them to obtain a compound bacterial agent. Among them, the above strains can be purchased from Yulin Desert King Biotechnology Co., Ltd.
