Problems solved by technology

[0003] The main reason for the degradation of the strains is that when the strains are artificially cultivated, the cultivation conditions are not suitable (external factors), including nutrition, temperature, humidity, ventilation, pH value, etc., which cannot meet its living requirements, so that the edible fungi lose their self-regulation. the ability to temporarily lose the normal physiological function, unable to express the good breed
As far as a certain strain is concerned, with the prolongation of cultivation and use time, the age of the individual is getting older, the metabolic function is gradually reduced, the ability to resist stress is lost, or the high-yield traits are lost, until it loses its use value

Abstract

The invention discloses a domestic fungus strain preservation medium and application and preservation method thereof, and relates to the technical field of microbe. The medium comprise kenaf fiber stalks, cottonseed husks, wheat bran, corn flour, cane sugar, calcium carbonate and biotin and does not include vitamin B1. The kenaf fiber stalks and the biotin are added to and vitamin B1 is deleted from a routine medium to form the new domestic fungus strain preservation medium, the problem of relatively high spawn degeneration rate due to multitime passage can be solved, and the mycelia growth speed of the strains is kept in a relatively high level.

Description

technical field [0001] The invention relates to the technical field of microorganisms, in particular to a culture medium for preserving edible fungus strains and its application and preservation method. Background technique [0002] Long-term use, storage, and too many transfer times of edible fungus strains will lead to a decline in mycelial viability. During the propagation of the strains, it is often found that some original good traits gradually disappear or deteriorate, and the growth is weak. Slow growth, late fruiting, low yield, poor quality and other changes. These phenomena are called "degeneration". [0003] The main reason for the degradation of the strains is that when the strains are artificially cultivated, the cultivation conditions are not suitable (external factors), including nutrition, temperature, humidity, ventilation, pH value, etc., which cannot meet its living requirements, so that the edible fungi lose their self-regulation. Ability, so that tempo...
