Edible fungi culture matrix prepared with fermentation fungi residues

Abstract

The invention provides an edible fungi culture matrix prepared with fermentation fungi residues. The matrix is prepared by the following method: weighing cotton seed hulls or mulberry sawdust, fermentation waste fungi residues and a calcium magnesium phosphate fertilizer according to the following mass proportion and mixing uniformly: 60-80 parts of mixture of mulberry sawdust and bran or cotton seed hulls, 14-35 parts of fermentation waste fungi residue, 1-3 parts of calcium magnesium phosphate fertilizer, 0.5-2 parts of sucrose and 1-3 parts of gypsum; adding water to the mixed material until the water content is 65-68% by mass; adjusting the pH value to 7.0+ / -0.2 with lime; preserving heat for 8-12 hours in a boiler at 100-110 DEG C; and naturally cooling to obtain the edible fungi culture matrix. The invention provides a method for recycling the fermentation waste fungi residues, which ferments the industrial waste residues through pollution-free and green treatment and turns waste into wealth, and not only reduces the cost of edible fungi culture, but also increases the yield of edible fungi and realizes economic benefits.

Description

(1) Technical field [0001] The invention relates to an edible fungus cultivation substrate prepared by using fermentation waste fungus residue, and provides a resource utilization approach of industrial fermentation waste fungus residue. (2) Background technology [0002] In the industrial production of fermentation, a large amount of organic solid waste residue is produced after large-scale fermentation and cultivation of production strains and extraction of target products. At present, there are two main ways to dispose of fermentation industrial waste, namely soil landfill or incineration. The following problems will be accompanied by landfill treatment of bacterial residues: (1) Occupying a large amount of land resources; (2) Acidic bacterial residues inhibit the growth of soil microorganisms and affect soil fertility; (3) Residual components interfere with the growth of surrounding plants and soil microorganisms. Normal growth has a strong side effect on the ecological...

AI Technical Summary

Problems solved by technology

The following problems will be accompanied by landfill treatment of bacterial residues: (1) Occupying a large amount of land resources; (2) Acidic bacterial residues inhibit the growth of soil microorganisms and affect soil fertility; (3) Residual components interfere with the growth of surrounding plants and soil microorganisms. Normal growth has strong side effects on the ecological environment; (4) The waste fungus residue is rich in nutrients, and a large amount of available resources are wasted in soil burial; (5) The fungus residue is easy to produce stench during the process of landfilling smell, pollution

However, the treatment of fungal residues by incineration requires high investment in equipment, high energy consumption for equipment operation, and desulfurization of exhaust gas, resulting in high costs for the treatment of waste fungal residues. The cost of processing waste fungal residues per ton is close to 1,000 yuan.
