Research Progress on Liquid Fermentation and Induction Culture of Bioactive Compounds from Boletaceae Fungi

Induction technology could be used to promote the production of bioactive components in the process of fungal fermentation, and these bioactive compounds from mycelia and fermentation liquor could be obtained by liquid state fermentation. In addition, the liquid fermentation technology of fungi has the advantages of high yield, short cycle and renewability, which has a broad application prospect in food, medicine and cosmetics industries. In recent years, the induction culture technique of fungal in fermentation industry has also been studied deeply worldwide. This paper reviewed the research status on liquid state fermentation of Boletaceae fungi, including fermentation culture and exogenous induction culture of exopolysaccharides, pigments, triterpenoids, chitosan and L-theanine, aiming to provide a theoretical reference for the liquid state fermentation and liquid strains of fungi, as well as a new method for the industrial manufacture of bioactive metabolites from fungi.
