| Abstract: | Summary: In this study we report both the development of dithiocarbamate resins from the commercial hypercrosslinked resin MN-250 and the evaluation of the biocidal capacity of this material against E. coli ATCC25922 suspensions. The preparation of dithiocarbamate resins followed a synthetic pathway based on nitration of resins, reduction of nitro groups and reaction with CS2 in an alkaline medium. The biocidal capacity was evaluated by means of elution of E. coli suspensions (103–107 cells/mL) through columns containing the resin and plating on LB nutrient medium solidified with Bacto agar. We can conclude that hypercrosslinked resins with dithiocarbamate groups have potential biocidal action. |
