Abstract

The invention belongs to the technical field of biological engineering. The invention aims at providing an edible mushroom culture medium prepared by adopting kelp residue as a main raw material. The culture medium contains 10 to 45 parts of the kelp residue, 10 to 25 parts of bran, 1 to 3 parts of plaster and 1 to 3 parts of cane sugar. The edible mushroom culture medium is scientific and reasonable in formula, not only can the technical problem that the price of a traditional culture medium is increased be overcome, but also the technical problem in the subsequent processing of the kelp residue can be solved.

Description

technical field [0001] The invention belongs to the technical field of bioengineering, and in particular relates to an edible fungus culture medium made from kelp slag. Background technique [0002] Edible mushrooms such as Flammulina velutipes, Pleurotus eryngii, and crab-flavored mushrooms have the advantages of tender meat, soft smoothness, pleasant taste, and high protein content, and are deeply loved by people. The growth of edible fungi mainly depends on the absorption of nutrients from the medium. The formula and nutrient ratio of the medium play a key role in the quality of edible fungi, the control of the harvest period and the yield. The traditional edible fungus culture medium is made of cottonseed husk as the main raw material. The crude fiber content in the cottonseed husk is about 45%, and the crude protein content is about 4.4%. Due to the rising domestic cottonseed hull price in recent years, the price of culture medium has been rising continuously, whi...
