Abstract

The invention relates to a trichoderma-resistant white flammulina velutipes strain, a method for screening the same and a cultivation material formula for trichoderma-resistant white flammulina velutipes fruiting bodies. A classification name of the trichoderma-resistant white flammulina velutipes strain is Flammulina velutipes, the trichoderma-resistant white flammulina velutipes strain is already preserved in the General Microorganism Center of the China Committee for Culture Collection of Microorganisms on 20th September, 2017, and a preservation number of the trichoderma-resistant white flammulina velutipes strain is CGMCC NO:14560.

Description

technical field [0001] The invention relates to the technical field of microbes, in particular to a Trichoderma-resistant Flammulina velutipes strain, a screening method thereof and a cultivation material formula. Background technique [0002] Flammulina velutipes (Flammulina velutipes), also known as construct bacteria, winter mushroom, hair handle money bacteria, is rich in various nutrients such as protein, polysaccharide, amino acid and dietary fiber, and has low fat content. It has anti-oxidation, anti-tumor, anti-virus, protective Liver, remove heavy metal ions, lower cholesterol, prevent high blood pressure and other functions, regular consumption can significantly improve human immunity. [0003] Flammulina velutipes varieties are divided into yellow Flammulina velutipes and white Flammulina velutipes according to the color of fruiting body. White Flammulina velutipes has become the main cultivar of Flammulina velutipes industrialized cultivation because of its tend...
