Research on the Technology of Liquid Deep Fermentation for Extracting Ergothioneine from Ganoderma tsugae Murr.
The extraction conditions of ergothione by liquid deep fermentation of Ganoderma tsugae Murr.were determined by single factor and orthogonal test.The results showed that the optimal extraction conditions were 60%of the maximum permissible liquid loading,200 r·min-1 rotation speed,pH=6,fermentation temperature 30℃,fermentation ventilation 0.6 L·min-1.
