Edible straw rotting fungus culture medium and preparation method thereof

Abstract

The invention belongs to the field of utilization of organic matters, and in particular relates to an edible straw rotting fungus culture medium and a preparation method thereof. The edible straw rotting fungus culture medium comprises the following components in percentage by weight: 40 to 50 percent of primary fungus chaff, 30 to 50 percent of xylitol residue, 5 to 20 percent of bran, 0.2 to 2 percent of calcium superphosphate, 0.2 to 1 percent of corn flour and 0.5 to 1 percent of gypsum. Lime milk and water are added into the medium, the pH is adjusted to be 8 to 10, and the water content is controlled to be 55 to 70 percent. The edible fungus culture medium is high in hypha running speed, hypha exuberantly grows, and the sundry fungus contamination rate can be greatly lowered; produced edible fungi have various nutritional characteristics of edible fungi produced by an ordinary culture material, and have a high edibleness and medicinal value.

Description

[0001] technical field [0002] The invention belongs to the field of organic matter utilization, and in particular relates to a grass rot type edible fungus substrate and a preparation method thereof. Background technique [0003] Edible fungi are not only delicious, but also rich in nutrition, containing a large amount of amino acids, multivitamins and a variety of physiologically active mineral elements, and are often called healthy food by people. There are various varieties of edible fungi with different characteristics. Only through cultivation and management can the fruiting bodies of various edible fungi be produced for people to enjoy, in order to show their edible value, medicinal value and economic value. Therefore, the cultivation of edible fungi is of great significance . [0004] Edible fungi can be divided into wood rot type and grass rot type according to their growth habits. Wood-rot edible fungi are a type of edible fungi with woody materials as the main ...

Problems solved by technology

These industrial biomass wastes rich in cellulose and lignin are difficult to handle and cause serious environmental pollution

[0007] At present, the treatment methods for red peony slag and xylitol slag mainly include: 1) stacking or burying them as waste, which not only takes up a lot of land, but also pollutes groundwater; 2) after drying the waste residue, incinerate at high temperature However, after incineration, a large amount of soot, carbon dioxide and other pollutants are produced, which also brings considerable pollution to the atmospheric environment.

In recent years, with the enhancement of people's awareness of environmental protection and the adjustment of national industrial policies, more and more treatment methods have been developed, such as biogas fermentation, composting, firing activated carbon, etc. These technologies have more or less solved some However, due to the low added value, poor operability, and poor economic benefits, it is difficult to promote it. More importantly, all these treatment methods have failed to effectively utilize the biological system in the waste residue. Therefore, a kind of Efficient waste biomass utilization technology has important practical and economic significance
