Study on the Antibacterial Activity of Fluorine Oligochitosan Derivatives
The antibacterial effects of six different structures of fluorine oligochitosan derivatives on Escherichia coli,Staphylo-coccus aureus , Sclerotinia sclerotiorum , Rhizoctonia cerealis , Rhizoctonia solani , Aspergillus niger and Penicillium were studied by filter paper method. The results showed that the antifungal activity of different fluorine oligochitosan derivatives showed different degrees of antimicrobial activity against different microorganisms. Among the six kinds of fluorine oligochitosan derivatives,except the compound 5 had no bacteriostasis against Aspergillus niger,several other compounds had different an-tibacterial properties against the seven tested strains. Compound 2 had better inhibitory effect on Escherichiacoli:Compounds 2 and 3 had bacteriostatic effect on 7 kinds of microorganisms,but the antibacterial effect was poor. Compound 4 had better inhibitory effect on Escherichiacoli,Staphylococcus aureus and Rhizoctonia solani;Compound 5 had better inhibitory effect on Escherichiacoli. Compound 6 had better effect on Staphylococcus aureus,Rhizoctonia cerealis and Rhizoctonia solani.
