Abstract:
Taking Ganoderma mycelium as material,the culture medium and fermentation conditions of Ganoderma for ganoderic acids were optimized through L18(37)orthogonal experimental design.The results showed that the significant effect factors was as follows:oleic acid,α-Naphthylacetic acid,L-Glutamic acid,the optimal medium composition:glucose 20 g/L,oybean powder 15 g/L,corn flour 40 g/L,oleic acid 2 g/L,α-Naphthylacetic acid 0.2 g/L,L-Glutamic acid 1.5 g/L,yeast extract 1.0 g/L,KH2PO4 02 g/L,MgSO4·7H2O 0.9 g/L,VB1 0.02 g/L;the content of ganoderic acids was 281.58±11.25 g/L under the conditions.
