Liquid strain of edible mushrooms and method for producing liquid strain of edible mushrooms

Abstract

The invention discloses a method for producing a liquid strain of edible mushrooms. The method for producing the liquid strain of the edible mushrooms comprises the steps that (1) the liquid strain of the edible mushrooms is inoculated in a PDA culture medium to be activated, and separation is conducted after cultivation so that an activated mycelium can be obtained; (2) the activated mycelium is inoculated in a solid-state saw dust culture medium to be cultivated for 28-32 days so that a recovery culture 1 composed of the mycelium and the solid-state saw dust culture medium can be obtained; (3) the recovery culture 1 is smashed into particles with the diameters ranging from 20 meshes to 40 meshes and then the particles are laid flat in a shallow plate with a thickness of 3 m-4m to be cultivated for 2-3 days in a sealed mode so that a recovery culture 2 can be obtained; (4) after the recovery culture 2 is smashed into small blocks with the diameter not larger than 0.5 cm, pulping is conducted by adding water to the small blocks, and then the obtained pulp and the agar solution with the concentration ranging from 0.15% to 0.2% are made to be in contact and evenly mixed. According to the method for producing the liquid strain of the edible mushrooms, operation is easy, a complicated cultivation device is not needed, and the production efficiency is high. The liquid strain, obtained according to the method, of the edible mushrooms has the advantages of being stable in quality, robust, slow in degeneration and easy to store and transport.

Description

technical field [0001] The invention relates to a liquid strain of edible fungus and a production method of the liquid strain. The production method of the liquid strain of edible fungus. Background technique [0002] In the existing edible fungus cultivation technology, solid strains are usually used for production. Traditional solid strains have the defects of long production cycle of edible fungi strains, large amount of strains, high production cost, and slow mycelial germination speed. It is not suitable for the application of shiitake mushrooms in large-scale production. [0003] The liquid strains commonly used in the prior art are produced by submerged culture techniques in biological fermenters using liquid culture medium. Although liquid strains have overcome the defects of long production cycle and high cost of traditional solid strains, there are still a series of problems that are not suitable for large-scale industrialization of shiitake mushrooms, such as lar...

AI Technical Summary

Problems solved by technology

Although liquid strains have overcome the defects of long production cycle and high cost of traditional solid strains, there are still a series of problems that are not suitable for large-scale industrialization of shiitake mushrooms, such as large investment in liquid fermentation production equipment, difficult pollution control, rapid mycelium aging, and strain variation. homework defects

[0004] In the existing production methods of solid liquefied strains at home and abroad, wood chips or pulp are used as the medium. Because the main components in the wood chips or pulp are only lignin and cellulose, the content of protein and trace elements is low, and the fiber content is low. Long, resulting in weak bacterial growth and difficult to dilute evenly, long preparation time, difficult to achieve industrial production
