Submerged fermentation Technology of Ganoderma lucidum Fungi
Ganoderma lucidum and Ganoderma lucidum bioactive substances have become a research hotspot in the field of new green feed additives because of their unique physical and chemical properties and magical biological functions. However, the artificial cultivation of Ganoderma lucidum has a long growth cycle (more than 2 ~ 3 months), which is greatly affected by the environment, low yield, unstable quality and high production cost, which greatly affects the development of Ganoderma lucidum and its bioactive substances in the feed industry. Therefore, in recent years, people turn to the study of liquid submerged fermentation culture of Ganoderma lucidum to obtain Ganoderma lucidum mycelium and its active growth metabolites (Ganoderma lucidum acid, Ganoderma lucidum polysaccharides, etc.), and through the control of fermentation conditions, shorten the production cycle and reduce the production cost. it is possible to apply and popularize Ganoderma lucidum and its bioactive feed additives in animal husbandry. The culture conditions and control of technological parameters of liquid submerged fermentation of Ganoderma lucidum were reviewed in this paper. The basic process of liquid submerged fermentation culture of Ganoderma lucidum fungi is to produce → spores to prepare → seeds to prepare → fermentation → fermentation products (extraction and purification) → products. In the process of liquid submerged fermentation, there are three main factors that affect the production cycle, production level and production cost: production strain, medium composition and fermentation process parameters.

Cultivation method of substitute material for Gastrodia elata at low altitude
Gastrodia elata is a kind of rare and precious traditional Chinese medicine, which used to rely on the wild and grow in the mountains above 500 meters above sea level. it is very rare and difficult to dig, and now it is facing extinction. The development of artificial cultivation of Gastrodia elata has saved this precious species, but technically it can not get rid of the cultivation at high altitude, and the raw materials are also inseparable from Duan Mu.

Ganoderma lucidum, also known as divine grass, ten thousand years grass, Ganoderma lucidum, Ganoderma lucidum, Ganoderma lucidum and so on. There are more than 40 kinds in China, and the more common and famous ones are Ganoderma lucidum, pine Ganoderma lucidum, black Ganoderma lucidum, Ganoderma lucidum and so on. Ganoderma lucidum has been used medicinally in China for more than two thousand years. In addition to containing potassium, phosphorus, magnesium, calcium, iron, manganese and other minerals.
