Abstract

The invention belongs to the field of plant endophyte separation and microbial fermentation engineering, and in particular relates to a method for preparing a crude torreya alkaloid product. By selecting the roots, stems, and leaves of perennial Torreya as explants, cutting them into strips, sterilizing them, and putting them into the culture medium to cultivate them to grow the symbiotic bacteria of Torreya, and then isolate the metabolizable Torreya symbiotic bacteria from the symbiotic bacteria. Torreya alkaloid strains are cultivated and fermented, and the product is obtained by concentrating the fermented liquid and separating out. In the present invention, in the preparation process of the fermentation liquid, the second batch of strains is inserted after the strains produce metabolic organisms, and the metabolites produced by the previous batch of strains are used to provide nutrients for the second batch of strains, which greatly promotes the production of the second batch of strains. The growth of the bacteria species improves its biological activity, thereby producing a large amount of fermentation liquid and improving the output of crude torreya alkaloids.

Description

technical field

[0001] The invention belongs to the field of plant endophyte separation and microbial fermentation engineering, and in particular relates to a method for preparing a crude torreya alkaloid product. Background technique

[0002] Torreya is a unique plant in my country, which has high nutritional value and economic value. Torreya alkaloid is one of the important active ingredients of Torreya, which has anti-cancer effects and is often used in medicine. At present, crude torreya resources are scarce, and the tree species grows slowly, and the output of crude torreya alkaloids is low, which is difficult to meet people's living needs. At the same time, it also causes the price of crude torreya alkaloids to be expensive. Therefore, how to increase the output of crude torreya alkaloids become one of the most important issues for people. Contents of the invention

[0003] The purpose of the present invention is to provide a method for preparing a crude torreya alk...
