经过十年的菌种、基质原料、配方筛选和栽培条件优化，我所完成了人工栽培技术熟化，大规模人工栽培中桦褐孔菌子实体产量达20-30g/袋（干重）、人工栽培子实体多糖含量与野生子实体相当、蛋白质含量是野生子实体的3倍以上、三萜含量比野生子实体提高10%以上，技术成果处于国内领先水平。目前已完成了人工栽培桦褐孔菌子实体多糖和三萜的提取工艺确立，研制出功能饮料、袋泡茶等产品配方及生产工艺。获得3项科研成果和2项发明专利。野生桦褐孔菌采集困难、产量低售价高。桦褐孔菌大规模人工栽培及产品开发项目实施利润空间大。可技术转让、合作开发。

Inonotus obliquus is a kind of medicinal fungus, which is rich in Bioactive substances of  polysaccharide, terpenoids, sterol, fuscoporine, etc. with the ability of anti-tumor, hypoglycemic, anti-aging, antiviral and boosting immunity. The application research of wild Inonotus obliquus has been developed in Russia, Japan, the United States, Korea, etc. but those countries have not yet mass production and cultivation. 

After 10 years’ selection and optimizing cultivation of bacterial species, substrate materials and its formula, our Institute has completed artificial cultivation technology maturation, in which the yield of large-scale artificial cultivation Inonotus obliquus’ fruit body reached to 20-30 g/bag ( dry weight), the polysaccharide content of artificial cultivated fruit body is quite equal to that of wild fruit body, protein content of it is more than 3 times that of wild fruit body, ganodera acid content is increased by more than 10 % than that of wild fruit body. Its technological achievements have a leading position in China. At present, the technology of artificial cultivated Inonotus obliquus’ fruit body polysaccharide and extraction process of triterpeniod has been completed, by which product formula and process of functional drinks and tea bag were developed. It has made 3 S&T outcomes and 2 invention patents.

Wild Inonotus obliquus is hard to collect, with the characteristics of low-yield and high-sales price. So the project for large-scale artificial cultivation and product development is enforced that will have a high profit pursuit. We can transfer technology and make cooperative development.
