Example Embodiment

[0015] Example 1

[0016] Preparation of rosin degradation additives:

[0017] The pine wood chips that have been naturally piled for 2 months are directly used as the inoculum of the microbial group that can degrade rosin substances, and the fresh pine wood chips are connected to the fresh pine wood chips at a dry weight ratio of 1:2, and mixed with water to form a pile. Pile for 60 days, add magnesium sulfate, potassium dihydrogen phosphate, and calcium carbonate inorganic nutrient salts, urea, and vitamin B organic nitrogen source, which can help microorganisms grow, and add 0.2% of the weight of dry pine sawdust. , Mix well, and then prepare the rosin degradation additive for the rapid degradation of rosin substances.

Example Embodiment

[0018] Example 2

[0019] Fast degradation of pine sawdust resin:

[0020] The dry pine sawdust was screened with a vibrating screen to remove impurities and large particles, and the rosin degradation additive prepared in Example 1 was added. The added amount was 5% of the weight of the dry pine sawdust. The natural piles were subjected to biological fermentation. When the temperature at the center of the stockpiles reaches 50-52℃, the pine resin content of pine sawdust can be reduced from 25.7g / kg to 5.4g / kg.

Abstract

A method for quickly degradating the rosin in pine dust used for culture mushrom features that the microbes able to quickly degradate, the rosin are separated out and cultured, and the cultured microbes are mixed with inorganic salt and organic substance to obtain a rosin-degradating additive.

Description

technical field [0001] The invention belongs to biological fermentation technology, and mainly relates to a method for degrading rosin substances in pine sawdust. Background technique [0002] Pine trees contain turpentine, and the main components of turpentine in turpentine are α-pinene and β-pinene. These unsaturated fatty acids are volatile, but they are very stable at room temperature. These stable low-molecular-weight oils can hinder and inhibit The growth and development of edible fungus mycelium, therefore, oxidative degradation of rosin substances in a short period of time, which will not affect the original nutrition of the material, and make the large fungi grow normally, is the key to using pine sawdust to cultivate edible fungi. The oxidative degradation of lipids by microorganisms has long been studied, especially under high temperature and high humidity conditions, some volatile low molecular weight unsaturated fatty acids are easier to be decomposed and oxidiz...
