Abstract

The invention relates to a needle mushroom strain detection culture medium and a usage method thereof, and belongs to the technical field of edible fungi strain degeneration detection. The invention aims at solving the technical problem of providing a needle mushroom strain activity degradation detection method which has the advantages of short detection period and high accuracy and a detection culture medium formula. The technical scheme is as follows: the needle mushroom strain detection culture medium comprises the following raw materials in parts by weight: 100-250 parts of potatoes, 10-30 parts of lactose, 1-3 parts of NH4NO3, 1-3 parts of KH2PO4, 0.1-1.5 parts of MgSO4.7H2O and 0.01-0.5 part of bromothymol blue. The needle mushroom strain detection culture medium disclosed by the invention can be used for culturing the strains to be detected; and according to the invention, the strains with good activity can decolorize the culture medium, and degraded strains or inactivated strains enable the color of the culture medium to be shallow or unchanged.

Description

technical field

[0001] The invention discloses a culture medium for detecting Flammulina velutipes strains and a method for using the same, belonging to the technical field of edible fungus strain degradation detection. Background technique

[0002] Flammulina velutipes is famous all over the world for its tenderness, crisp stalk, rich nutrition, tangy fragrance and delicious taste, and is deeply loved by the public. Due to the expansion of market demand, the industrial cultivation of Flammulina velutipes has developed rapidly in recent years, and a series of problems have also arisen, among which the degradation of strain activity is one of the most influential problems. During the continuous passage of Flammulina velutipes strains in PDA medium, the activity of the strains will be degraded. If the low-activity strains are not found until the fruiting body is formed in this continuous production process, serious economic losses will be caused. .

[0003] At present, there...
