Figure 5
Morphological observation of Astragalus fermented for different durations. (a) After fermentation for 24 h probiotics (red arrows) were attached to the surface of Astragalus. (b) Holes (red arrows) became evident on Astragalus surface after fermentation for 48 h. (c) Higher magnification clearly showed these holes (red arrows) after fermentation for 48 h.
