specific Embodiment approach 1

[0019] Specific implementation mode 1: In this embodiment, the endophytic fungus fermenting Schisandra chinensis to increase the content of the main active components of Schisandra chinensis is Aspergillus niger WJ1, which has been preserved in the China Center for Type Culture Collection, and the preservation number is CCTCC No: M2012044 , the deposit address is Wuhan University, Wuhan, and the deposit date is February 29, 2012.

[0020] In the present embodiment, Aspergillus niger (Aspergillus niger) WJ1 is cultivated on the PDA solid medium, and the hyphae are white at the beginning, and then become black velvet, and the back is colorless, and the top of the bacterial strain forms a spherical apical capsule, which is fully covered A layer of stalk base and a layer of small stalks, on which there are clusters of dark brown spherical conidia, the diameter of the spores is 3.5 μm, the head of the conidia is spherical, brown-black (such as figure 1 , 2 and 3).

Abstract

The invention relates to a strain of endophytic fungus, in particular to a strain of endophytic fungus of fermenting schisandra chinensis to improve main active components of schisandra chinensis. The strain of endophytic fungus of fermenting schisandra chinensis to improve main active components of schisandra chinensis is aspergillus niger WJ1, which is preserved in China Center for Type CultureCollection on Feb. 29th, 2012, the preservation number is CCTCC No. M2012044, and the preservation address is Wuhan University in Wuhan. The aspergillus niger WJ1 provided in the invention can substantially improve main active components including schisadrol A, schisantherin A, deoxyschizandrin, schisandrin B, and the like of schisandra chinensis. Thus, in raw material productions aiming at obtaining schisadrol A, schisantherin A, deoxyschizandrin, and schisandrin B, the schisandra chinensis endophytic fungus WJ1 can be selected to ferment schisandra chinensis, thereby improving yield and saving medicine resources.

Description

technical field [0001] The present invention relates to an endophytic fungus. Background technique [0002] Schisandra chinensis (Turcz.) Baill.], the dry and mature fruit of Schisandra chinensis (Turcz.) Baill.], is a functional health food that is both edible and medicinal. The active ingredients of Schisandra chinensis are lignans represented by schisandra alcohol A, schisandrin ester A, schisandrin A, schisandrin B, etc. These ingredients have obvious anti-cancer, anti-inflammatory, sedative, anti-anxiety, protective Liver cells have anti-chemical liver damage and antibacterial effects, and are now widely used in the pharmaceutical and food industries. Due to the increasing demand for Schisandra chinensis, the gradual reduction of forest area and blind excavation, the resources of Schisandra schisandra are facing challenges. At present, Schisandra chinensis is an endangered medicinal plant under the national third-level key protection. [0003] Fermentation technology ...
