Problems solved by technology

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 oxidized by microorganisms, the time required for oxidation and degradation under natural conditions Too long, can't realize industrialization, research is suitable for the method for fast degrading rosin in the pine sawdust of industrialized cultivation edible fungus, still needs further realization and improvement

Embodiment 1

[0016] Preparation of pine resin degradation additive:

[0017] Select the pine sawdust that has been stacked and retting for 2 months directly as the inoculum of the microbial groups that can degrade turpentine substances, and put the fresh pine sawdust into the fresh pine sawdust according to the dry weight ratio of 1:2, add water and mix well to form a heap. Stack retting for 60 days, after drying in the shade, add magnesium sulfate, potassium dihydrogen phosphate, and calcium carbonate inorganic nutrients, urea, and vitamin B organic nitrogen source, which are conducive to microbial growth, and the addition amount is 0.2% of the weight of dry pine sawdust and mix well to prepare a rosin degradation additive for rapidly degrading rosin substances.

Embodiment 2

[0019] Rapid degradation of pine sawdust turpentine:

[0020] The dry pine sawdust is screened with a vibrating sieve, removes sundries and large particles, adds the rosin degradation additive made in Example 1, and the addition is 5% of the dry pine sawdust weight, naturally piles up and carries out biological fermentation, after 5 In one day, when the temperature in the center of the stack reaches 50-52°C, the content of pine resin in 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...
