Abstract  

Single-factor and response surface test were used for optimization of Ganoderma lucidum medicinal solid fermentation medium. Optimized medium composition were as follows: brewer's spent grain as substrate, the ratio of material to water was 1∶1.4, Astragalus membranaceus 12.52%, glucose 4.78%, KH2PO40.21%, MgSO4·7H2O 0.25%, VB1 trace. Under the optimized conditions, GAPS concertration reached up 8.42mg/g, increased by 29.54% compared with unoptimization.
