Problems solved by technology
[0005] The purpose of the present invention is to solve the problem that in the prior art, the technology of increasing the polysaccharide content of black fungus through fermentation and cultivation does not consider strictly controlling the cultivation parameters of black fungus at the germination stage and does not monitor the relevant environmental parameters of black fungus cultivation during the fermentation process. Adjustment, resulting in poor development of fungus

The invention relates to a method for increasing the auricularia auricula polysaccharide content by adopting a submerged fermentation technology. The method comprises the following steps that the growth speed of auricularia auricula hyphae in a culture bottle is monitored in a spawn running stage, environment parameters are regulated in the spawn running stage by combining parameters of a gravity sensor, the spawn running speed and spawn running quality in the spawn running stage of auricularia auricula is ensured, meanwhile, a fermentation process and nitric oxide and ethylene synergistic induction treatment are adopted, the content of auricularia auricula polysaccharide is increased, meanwhile, the fermentation cultivation stage is monitored, the fermentation effect is represented through the bubble forming speed in the fermentation cultivation process, the fermentation duration and environment parameters in the fermentation process are accurately controlled, the auricularia auricula starch forming quality and the strain plumpness are improved while the auricularia auricula polysaccharide content is increased through induced fermentation, and then the polysaccharide content of the auricularia auricula is further increased.
Description
technical field [0001] The invention relates to the field of fungi cultivation, in particular to a method for increasing the polysaccharide content of auricularia auricula by adopting submerged fermentation technology. Background technique [0002] Black fungus [Auricularia auricula (L.ex Hook.) Underw], also known as black cabbage, black fungus, and cloud ear, belongs to the family Auriculariaceae and the genus Auricularia. It is a precious colloidal fungus for both medicine and food in my country, and it is also a recognized health food in the world. my country is the hometown of black fungus. The Chinese nation knew and developed black fungus as early as the Shennong era more than 4,000 years ago, and began to cultivate and eat it. "Book of Rites" also has records about eating black fungus at the emperor's banquet. At present, black fungus is planted in the northeast, north, south-central, southwest and coastal provinces of China. According to modern scientific analysis, t...
