Problems solved by technology

[0002] There are generally three types of cultivation of edible fungus strains according to the composition of nutrients: 1. Natural medium: The medium is prepared from natural organic matter, with wide sources of materials, low cost, and simple production, but the composition is unstable, so it is not suitable for precise use. 2. Semi-synthetic medium: add inorganic salts to the natural medium or add a small amount of organic matter to the synthetic medium. Silk growth; 3. Synthetic medium: The composition of the medium is clear and stable, and it is suitable for experiments, separation of mother species, and storage of strains. However, the existing synthetic medium has complex formulas, many preparation steps, and uses more grain raw materials. higher

Abstract

The invention discloses a straw fermentation substrate, a domestic fungus bacterial strain culture medium, and a preparation method thereof. The domestic fungus bacterial strain culture medium is prepared from, by weight, 60 to 80 parts of the straw fermentation substrate by dry weight, 5 to 10 parts of corn powder, 5 to 10 parts of fish meal, 2 to 5 parts of glucose, 0.05 to 0.1 part of lime, 0.05 to 0.1 part of gypsum, 0.005 to 0.01 part of potassium dihydrogen phosphate, and 0.05 to 0.1 part of magnesium sulfate. The formula and the preparation steps are simplified; the common raw materialsare adopted; using of grain raw materials is reduced; grain resource is saved; cost is reduced; a plurality of nutrients needed by domestic fungus are provided; and the domestic fungus bacterial strain culture medium is abundant and comprehensive in nutrients.
