Culture medium for pleurotus eryngii strain cultivation

Abstract

The invention discloses a culture medium for pleurotus eryngii strain cultivation. The culture medium is prepared from, by weight, 20-60 parts of potatoes, 10-30 parts of bran, 2-8 parts of glucose, 1-5 parts of agar powder, 2-6 parts of tryptone, 3-9 parts of highland barley extract, 2-6 parts of yeast extract, 2-6 parts of sodium chloride, 1-3 parts of magnesium sulfate, 2-4 parts of monopotassium phosphate, 2-4 parts of water, 3-9 parts of a solid medium raw material and 2-6 parts of a nutritional agent. According to the culture medium for pleurotus eryngii strain cultivation, the potatoes, the bran and the highland barley extract are taken as raw material sources of flour and crude protein, nutrient elements and carbohydrate can be fully supplemented by adding glucose, sodium chloride, magnesium sulfate, monopotassium phosphate, the water, the solid medium raw material and the nutritional agent, therefore, the culture medium can fully meet nutrients and microelements needed by production of pleurotus eryngii strains, and the production efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of biological bacteria cultivation, in particular to a medium for cultivating Pleurotus eryngii strains. Background technique [0002] Pleurotus eryngii is an important fungus with edible and medicinal value, and its fermentation liquid contains a large number of secondary metabolites. [0003] When cultivating the Pleurotus eryngii strains in the prior art, due to the lack of nutritional raw materials and trace elements, the cultivation of the Pleurotus eryngii strains is stunted, which seriously affects the normal production demand. Contents of the invention [0004] The present invention proposes a culture medium for Pleurotus eryngii strains, the raw materials of which include by weight: 20-60 parts of potatoes, 10-30 parts of bran, 2-8 parts of glucose, and 1-5 parts of agar powder , 2-6 parts of tryptone, 3-9 parts of barley extract, 2-6 parts of yeast extract, 2-6 parts of sodium chloride, 1-3 part...
