Solid lucid ganoderma strain and application thereof in submerged fermentation of lucid ganoderma

Abstract

The invention discloses a solid lucid ganoderma strain and an application thereof in submerged fermentation of lucid ganoderma. Peanut shell powder and bran powder or fine rice bran are taken as raw materials and are prepared into compost, an activated lucid ganoderma slant strain is taken as a stock strain and the dark culture is performed in a strain bottle or a polypropylene plastic strain bag, so as to acquire the solid lucid ganoderma strain. Compared with the traditional liquid strain (primary in mycelium pellet), the solid lucid ganoderma strain disclosed by the invention has the advantages of low strain cost, long preservation time and direct application to liquid fermentation; the frequent preparation for the fermentation strain can be avoided and the increasing of the working efficiency is benefited; when the solid lucid ganoderma strain is used as the strain for the submerged fermentation culture of lucid ganoderma, the dispersity is high and a large amount of hypha growing points can be formed, so that the fermentation efficiency of the lucid ganoderma can be greatly promoted, the extracellular polysaccharide and biomass of the lucid ganoderma are obviously increased, the fermentation pollution rate can be reduced and the application prospect is extremely wide.

Description

technical field [0001] The invention belongs to the field of medicinal fungi and bioengineering applications, and in particular relates to a ganoderma solid strain and its application in ganoderma liquid submerged fermentation. Background technique [0002] Ganoderma lucidum ( Ganoderma lucidum ) is also known as Xiancao, Ruicao, Shenzhi, and not old grass. It belongs to Basidiomycetes, Agaricaceae, Polyporaceae, and Ganoderma fungus. It grows on the trunks and branches of different dead or growing broad-leaved trees. The ancients believed that It has the magical effect of bringing the dead back to life. Ganoderma lucidum in China mainly refers to lucidum with medicinal value, including red lucidum, purple lucidum, and pine and fir ganoderma. Ganoderma lucidum has a medicinal history of more than 2,000 years in my country and other oriental countries, and can be used for the treatment of various diseases such as hepatitis, hypertension, hyperlipidemia and gastric cancer. ...

AI Technical Summary

Problems solved by technology

At present, ganoderma lucidum liquid submerged fermentation usually uses spheroid-type liquid strains as fermentation seeds, but the slow growth of ganoderma lucidum mycelium leads to a long period of strain preparation, and microbial contamination is prone to occur during operation and cultivation, resulting in failure of strain preparation , affecting production, and the fermentation process requires frequent preparation of liquid strains, the process is cumbersome
