Application of chitosan-oligosaccharide containing composition in production of edible fungi

Abstract

The invention relates to an application of a chitosan-oligosaccharide containing composition to the production of edible fungi and particularly provides a culture solution for producing an edible fungi. The culture solution comprises a growth factor, a carbon source, a nitrogen source, an inorganic salt and water, wherein the growth factor comprises chitosan oligosaccharide and humic acid which are at the weight ratio of 1:(20-100); the growth factor accounts for 5-15% of the total weight of the culture solution, the carbon source accounts for 10-30% of the total weight of the culture solution, the nitrogen source accounts for 10-30% of the total weight of the culture solution, the inorganic salt accounts for 1-10% of the total weight of the culture solution, and the balance of water. The invention provides the application of the composition containing the chitosan oligosaccharide and the humic acid to the production of a variety of edible fungi. The method for culturing the edible fungi comprises the steps of culturing the culture solution containing the chitosan oligosaccharide and the humic acid and atomizing by using an edible fungus bag. The growth of the mycelium can be promoted, the yield of the fruiting body can be increased, and the quality of the fruiting body can be improved.

Description

technical field [0001] The invention belongs to the field of edible fungus production, and in particular relates to the application of a composition containing chitosan oligosaccharide in the production of edible fungi. Background technique [0002] According to reports, there are more than 350 kinds of edible fungi known in China, the common ones are straw mushrooms, enoki mushrooms, bamboo fungus, shiitake mushrooms, fungus, white fungus, Hericium erinaceus, matsutake mushrooms, red mushrooms, mushrooms, oyster mushrooms, pleurotus eryngii, and ganoderma lucidum. , Dictyophora etc. Edible mushrooms are not only precious delicacies, but also high molecular polysaccharides, β-glucose, nucleic acid degradation products, and triterpenoids, which have anti-tumor and immune-enhancing effects, have important medicinal and health care values ​​for human health. How to improve the output of edible fungi mycelium and fruiting bodies is a problem that edible fungus producers pay clo...
