preparation example Construction

[0022] The preparation of decomposing accelerator of the present invention is through following two steps:

[0023] 1. Seed culture: Scrape the purified cultured Bacillus subtilis, Aspergillus oryzae, Trichoderma reesei, Streptomyces coeruleus and purchased Phanerochaete chrysosporium from the preserved slant culture medium, and inoculate them respectively on Nutrient gravy medium, bean juice medium, Chase medium, Gao's No. 1 medium and potato sucrose medium, each 1 liter Erlenmeyer flask is filled with 200ml of liquid medium, the culture temperature is 30-37 ° C, at 150 Shake culture at ~180rpm for 24~60h.

[0024] 2. Fermentation and enzyme production culture: inoculate the above-mentioned seed culture solution into respective fermentation media with an inoculum amount of 5-8%.

[0025] The fermentation media of Bacillus subtilis, Aspergillus oryzae, Trichoderma reesei and Streptomyces coulerus have the same composition, and the formula contains (weight ratio): 2-3% of rice...

Abstract

The present invention is decay promoting ferment and its application in composting agricultural waste to promote the degradation of hemicellulose, cellulose and lignin. The decay promoting ferment is one compound fermented liquid compounded with the fermented liquid of starch decomposing bacteria, pectin decomposing bacteria, hemicellulose decomposing bacteria, cellulose decomposing bacteria and lignin decomposing bacteria, and through filtering off thallus and mixing. It is added into and mixed with the compost material, with the added amount being 0.8-1.5 wt% of the compost material. It can promote the degradation of starch and other easy-to-degrade matters as well as pectin, lignin and cellulose. It has fast fermentation temperature raising and simple use, and can promote composting efficiency and improve compost quality.

Description

technical field [0001] The invention relates to a decomposing accelerator, in particular to a composite fermented liquid prepared by mixing crude enzyme liquids fermented by different microorganisms and its application in composting agricultural waste. Background technique [0002] my country produces more than 700 million tons of crop straw every year, and most of these materials are directly invaded into the environment as agricultural waste in the form of accumulation and burning, causing great environmental pollution and waste of resources. Aerobic composting is an important means of resourceful and harmless treatment of agricultural waste. Traditional aerobic composting mainly uses the indigenous microorganisms in the compost to metabolize and decompose organic matter, but since the cell walls of plant tissues in agricultural waste are mainly composed of pectin, cellulose, hemicellulose and lignin, the structure Stable and not easy to degrade, especially the refractory...
