The application discloses a selenium-rich Phellinus baumii strain domestication, cultivation and selenium enrichment method, which follows the gradient domestication principle of low-selenium starting and gradual increase, sequentially completes selenium source domestication of the Phellinus baumii primary mother strain, secondary original strain and tertiary cultivation strain, and obtains the cultivation strain suitable for the high-selenium environment; then, the tertiary cultivation strain is taken as the inoculation source, standardized cultivation is carried out by adopting the bagged solid culture medium, and the temperature, humidity, light and air conditions are regulated and controlled in two stages of mycelium culture and fruiting body growth management; and through gradient selenium source supply, continuous selenium supplement during the cultivation period, accurate regulation and control of the environmental conditions and scientific treatment after harvesting, efficient absorption and conversion of selenium by the Phellinus baumii are realized, inorganic selenium is converted into organic selenium, and the organic selenium is enriched in the fruiting body. The application solves the problems of low selenium tolerance and poor selenium enrichment efficiency of the Phellinus baumii, the selenium-rich Phellinus baumii fruiting body has high and stable organic selenium content, and the strain domestication success rate and cultivation survival rate are greatly improved.

This invention relates to the field of microbial fermentation technology, and particularly to a co-culture fermentation broth of medicinal and edible fungi with whitening effects, its preparation method, and its application. The preparation method of the co-culture fermentation broth of medicinal and edible fungi with whitening effects includes: inoculating the seed liquid of a first fungus and the seed liquid of a second fungus into a co-fermentation medium for fermentation and co-culture to obtain the co-culture fermentation broth of medicinal and edible fungi with whitening effects; the first fungus includes at least one of *Ganoderma lucidum* strain, *Trametes versicolor* strain, *Poria cocos* strain, *Auricularia auricula-judae* strain, *Phellinus linteus* strain, and *Aspergillus schavar*; the second fungus includes *Schizophyllum commune*. This invention co-cultures *Schizophyllum commune* with other specific strains and found that co-culturing the two strains can exert a synergistic effect, thereby significantly improving the tyrosinase inhibition effect of the fermentation broth. The optimal combination of fermentation broth can achieve a tyrosinase inhibition rate of over 90%, and even 1 wt% of the fermentation broth has a tyrosinase inhibition effect of approximately 90%.
