  • Biodegradation of antimicrobial treated cellulose textile substrates [Elektronski vir]
    Jaušovec, Darja, 1977- ...
    The influence of antimicrobial agent, 3-(trimethoxysilyl)-propyldimethyloctadecyl ammonium chloride (TMPAC), on the biodegradation of cellulose textile substrates was investigated. In the first part ... of the work, changes in surface morphology of TMPAC treated cotton in comparison with untreated cotton after the soil exposure tests were investigated by Scanning Electron Microscopy (SEM) and the chemical changes during the degradation process were investigated by FT-IR ATR spectroscopy. Secondly, the adsorption of antimicrobial agent onto the model cellulose film was performed and influence of the antimicrobial agent on the degradation of model cellulose film after addition of two enzymes produced from Trichoderma viride and Aspergillus niger was investigated. Results show fast initial adsorption of antimicrobial agent on the model film followed by slower adsorption over the following hours. Significant differences in film mass and film thickness were obtained when pure model cellulose film and model cellulose film treated with TMPAC were exposed to two different concentrations of enzyme extracted from Trichoderma viride. On the basis of optical properties of the investigated cellulose layer it can be concluded that TMPAC significantly decreases the degradation rate when enzyme Trichoderma viride was used, whereas it did not affect the Aspergillus niger cellulase activity, which anyhow was much lower.
