Screening of Liquid Fermentation Mediums of Small Mushrooms from Wutai Mountains

Objective] To optimize the best formula of liquid fermentation mediums of small mushrooms from Wutai Mountains.Method] Through a single factor experiment, the effects of commonly used carbon and nitrogen sources ( glucose, sucrose, potato juice, and inorganic salt) on the mycelial biomass of small mushrooms from Wutai Mountains were studied . Result] The best formula of the liquid fermentation medium of small mushrooms from Wutai Mountains are shown as follows: sucrose3 .0%, bran juice 3.0%, corn flour 5.0%, potato juice 30%, vegetation juice 10%, NaNO3 0.3%, K2HPO4 0.1%, KCl 0.1%, FeSO4 0.001%, and pH=7.Conclusion] The optimized formula of the liquid fermentation medium can significantly improve the mycelial biomass of small mushrooms from Wutai Mountains , so it is economi-cal and reasonable.
