Abstract:
Objective: To explore the bidirectional solid fermentation transformation of 25 different edible fungal strains with Isatidis Radix (IR) and Isatidis Folium (IF) to get the synergism antibacterial effect of fermentation substance. Methods: The dominant strains grown on IR and IF were obtained through initial screening and repeated screening. The antibacterial effect of fermentation product substance were determined by antibacterial test and TLC. Results: The results showed that repeated screening got three strains which could grow fast in IR (G-11, G-13, and G-7) and IF (G-2, G-11, and G-3). The G-3 strain and G-11 strain fermentation substance had better antibacterial effect than IR and IF respectively. The methanol extract of G-2 fermented IF substance appeared a new spot by TCL, it should be an additional component after fermentation. Conclusion: The bidirectional solid fermentation could improved antibacterial effect of IR and IF, and the new active ingredients can be produced.
