Through a comparative study of the bacteriostatic effect of nanosilver of different species and concentrations against bacteria, it is found that nanosilver have significant bacteriostatic effect against bacteria. Bateriostatic effect of nanosilve 15# against B. thuringiensis is significantly better than E.coli, s. aureus and B. subtillis. The optimal concentrations of 15# for inhabiting E. coli, S. aureus, B. subtillis and B. thuringiensis respectively are: 20 mg/L, 10 mg/L, 1 mg/L, 40 mg/L. nanosilvers of 13#, 14# and 15# have no significant differences in the bacteriostatic effect against E.coli, but are all significantly better than the bacteriostats of lincomycin hydrochloride and streptomycin sulfate. Antibacterial principle of nanosilver is damaging the cell membrane permeability.
