NOVEL CHITOSAN DERIVATIVES AS FILMS WITH AN ANTIMICROBIAL EFFECT
Journal Title: Progress on Chemistry and Application of Chitin and its Derivatives - Year 2013, Vol 0, Issue
Abstract
This paper presents the results of chitosan acylation with linoleic (LA) and dilinoleic acid (DLA). The chemical structures of the new derivatives with different degrees of substitution of LA and DLA were assessed by Fourier transform infrared spectroscopy. Polymer films were prepared by solution casting and drying. The resistance of films to bacterial degradation was tested according ISO 846 standard: “Plastic-Evaluation of the Action of Microorganisms” and the antimicrobial properties were assessed using Gram-negative bacterium Escherichia coli and the fungi Candida albicans in an agar diffusion test. Bioassays showed an antimicrobial effect in direct contact with the material.

IN VIVO STIMULATION OF PERITONEAL CELLS BY CHITOSAN ADMINISTERED IN DRINKING WATER TO MICE
The aim of the study was to determine immunostimulant properties of chitosan administered alimentary to BALB/c mice. We observed that chitosan feeding effected in activation of cells from the peritoneal cavity. The cells...
DETERMINATION OF DEGREE OF DEACETYLATION OF CHITOSAN - COMPARISION OF METHODS
Degree of deacetylation (DD) is one of the main parameters characterizing chitosan. The most precise measurements of DD require sophisticated equipment (NMR spectrometer), not available at many laboratories worldwide wor...
CHITOSAN APPLIED FOR GYPSUM MODIFICATION
In order to improve the properties of gypsum materials, including workability, mechanical strength and ability to retain water, various admixtures (also polymers), known as plasticisers, have been applied. These polymers...
ANALYSIS OF MODEL DRUG RELEASE KINETICS FROM COMPLEX MATRICES OF POLYLACTIDE-CHITOSAN
In the present paper the Authors analyse the experimental results of a model drug (ibuprofen) release approximated with three commonly used semi-empirical models: Korsmeyer-Peppas, first order kinetics and Gallagher-Corr...
THE INHIBITION OF HUMAN PLATELET AGGREGATION BY A LOW-MOLECULAR WEIGHT CHITOSAN
Chitosan derivatives were obtained by chemical (MW of 6 kDa, DD 99% - Ch6/99; MW13 kDa, DD 98% - Ch13/98) and enzymatic (MW of 5 kDa, DD 85% - Ch5/85; MW of 10 kDa, DD 85% - Ch10/85) depolymeri-sation of chitosan with a...
