Abstract

A strain of Clarobacterium, which is named as Clarobacterium XCS-6, has a preservation number of CGMCC No.9817 in the General Microorganism Center of China Microbiological Culture Collection Management Committee, and the preservation date is October 22, 2014. The sclerotium strain can be applied to prepare valerenin. Specifically, the sclerotium strain is fermented and cultivated by using a liquid medium, oscillating on a shaker, and cultivated at normal temperature for at least 6 days to obtain a valerenin-containing fermented liquid. After firstly applying the clariatium XCS-6 of the present invention to prepare valerianin, the valerianin can also be used to prepare sedative and hypnotic Chinese patent medicines.

Description

technical field

[0001] The invention relates to a valerianin-producing endophytic fungus and its application, in particular to a sclerobacter strain and its application. Background technique

[0002] As a new microbial resource, plant endophytes have attracted extensive attention from scholars at home and abroad. Discovering new active substances from plant endophytes has become a research hotspot. Studies have shown that endophytic fungi parasitic in medicinal plants can not only promote the production of certain secondary metabolites in host plants, but also produce the same or similar metabolites themselves. Most of the metabolites have obvious anti-tumor, anti-oxidation, antibacterial and other effects, and are good pharmaceutical raw materials.

[0003] Valerian (Valeriana officinalis L.) is a plant of the genus Valeriana in the family Patillaceae. It is an important traditional medicinal plant in my country. Its rhizome and root are used as medicine, and it has the ef...

Examples

Embodiment

[0029] We adopt the method of microbiology, isolate the endophytic fungus that produces valerenin from the healthy valerian plant, then utilize PDA liquid medium to ferment, adopt HPLC method to measure the content of valerenin in the fermented liquid, determine that it is An endophytic fungus producing valerianin was identified through morphological observation and ITS sequence analysis, and its species was determined to be Ceratobacterium XCS-6. The whole isolation and screening , Identify and prepare the specific operation process of valerian as follows.

[0030] 1. Isolation and screening of endophytic fungi producing valerianin

[0031] Valerian explants: Valerian is collected from the mountainous area of ​​Guiyang City, Guizhou Province. It is identified as Valeriana officinale by Professor Jiang Lijuan of Central South University of Forestry and Technology.

[0032] Explant disinfection: the fresh valerian root was rinsed with tap water for 10 minutes, and washed 3 tim...
