Method for production of high protein feed from edible fungus chaff

Abstract

The invention discloses a method for production of high protein feed from edible fungus chaff. The method specifically includes: breaking a fungus stick to obtain fungus chaff, adding an enzyme production induction liquid, then conducting culture under suitable conditions, eluting the fermentation system to obtain ligninase and efficiently transformed fungus chaff, then adding Tenebrio molitor, fly larvae, earthworms, locusts, silkworm chrysalis and other insect larvae into the remaining material to conduct culture, thus obtaining a high protein feed culture system. Compared with other production processes producing feed from biomass, the method can acquire ligninase, and realizes absorption and utilization of fungus chaff residue by the insect larvae so as to obtain the high protein feed. And pollution generated in the edible fungus production process is reduced.

Description

technical field [0001] A method for producing high-protein feed by using edible fungus chaff, in particular to a method for producing high-protein feed by using edible fungus chaff. It belongs to the technical field of bioengineering. Background technique [0002] Edible fungus bran refers to the complex of edible fungi and biomass raw materials after or before mushroom production in the production process of edible fungi. It is rich in bacterial protein, so it is called fungus bran protein. According to measurements, the protein content in the fungus chaff reaches 12% to 21%. However, since edible fungus chaff is grown from a variety of cellulose and lignin-rich sources such as chaff, straw, wood chips, etc., although fungus chaff contains a large amount of fungal chaff protein, it cannot be directly added to animal diets as feed. Because the crude fiber of the original edible mushroom residue is very high, which is higher than the standard of digestion and absorption of ...

Problems solved by technology

However, since edible fungus chaff is grown from a variety of cellulose and lignin-rich sources such as chaff, straw, wood chips, etc., although fungus chaff contains a large amount of fungal chaff protein, it cannot be directly added to animal diets as feed. Because the crude fiber of the original edible mushroom residue is very high, which is higher than the standard of digestion and absorption of ordinary animals, and the smell and palatability cannot meet the feeding conditions, and it cannot be stored for a long time

Therefore, at present, edible fungus residues are used to be dried and then incinerated or landfilled. The drying process may cause the reproduction of pathogenic bacteria, and incineration will also cause air pollution.

Not only did not give full play to the economic value of the fungus chaff, but it also brought pollution
