Summary: In this study we report both the development of dithiocarbamate resinsfrom the commercial hypercrosslinked resin MN-250 and the evaluation of thebiocidal capacity of this material against E. coli ATCC25922 suspensions. Thepreparation of dithiocarbamate resins followed a synthetic pathway based onnitration of resins, reduction of nitro groups and reaction with CS 2 in an alkalinemedium. The biocidal capacity was evaluated by means of elution of E. coli suspen-sions (10 3 –10 7 cells/mL) through columns containing the resin and plating on LBnutrient medium solidified with Bacto agar. We can conclude that hypercrosslinkedresins with dithiocarbamate groups have potential biocidal action. Keywords: biological applications of polymers; dithiocarbamate resins; functionalization ofpolymers; hypercrosslinked resins Introduction Waterborne diseases remain the leadingcause of death in many developing nations.Approximately 30% of all cases of death inLatin America are associated with inges-tion of contaminated water. In Brazil, manyhospital admissions are attributable tothe lack of sanitation in communities. |
