Antimicrobial properties of chitosan solutions, chitosan films
and gelatin-chitosan films (in English)

Polimery 2015, No 11-12, 735


DOI: dx.doi.org/10.14314/polimery.2015.735

Summary
The antimicrobial properties of chitosan solutions and films against selected bacteria and the effect of chitosan incorporation into gelatin films were studied. The bactericidal effect of chitosan solutions increased with time and temperature of sample incubation. Two psychrotrophic strains Pseudomonas fluorescens and Listeria innocua were more sensitive to chitosan than mesophilic strains Escherichia coli and Staphylococcus aureus. The growth of bacteria under chitosan discs was inhibited. In the case of two component gelatin-chitosan films strong antimicrobial effect was also observed.
