20.500.12556/RUL-133140 Antibacterial activity and biodegradation of cellulose fiber blends with incorporated ZnO This research aimed to study the influence of lyocell with incorporated ZnO (CLY) for antibacterial activity and biodegradation of fiber blends composed of viscose (CV), flax (LI), and CLY. Fiber blended samples with an increased weight fraction of CLY fibers were composed, and single CLY, CV and LI fibers were also used for comparison. Antibacterial activity was determined for the Gram-negative Escherichia coli and the Gram-positive Staphylococcus aureus bacteria. The biodegradation of fiber blends was investigated by the soil burial test. The results show that the single CLY fibers exhibited high antimicrobial activity against both E. coli and S. aureus bacteria and that the presence of LI fibers in the blended samples did not significantly affect antibacterial activity against E. coli, but drastically decreased the antibacterial activity against S. aureus. LI fibers strongly promoted the growth of S. aureus and, consequently, impaired the antimicrobial performance of ZnO against this bacterium. The presence of CLY fibers slowed down, but did not prevent, the biodegradation process of the fiber blends, even at the highest ZnO concentration. The soil that was in contact with the fiber blended samples during their burial was not contaminated to such an extent as to affect the growth of sprouts, confirming the sustainability of the fiber blends. fiber blends cellulose fibers ZnO antibacterial activity biodegradation soil contamination mešanica vlaken celulozna vlakna ZnO protimikrobna aktivnost biorazgradljivost onesnaženost tal true false true Angleški jezik Slovenski jezik Članek v reviji 2021-11-12 14:24:20 2021-11-12 14:24:21 2022-09-12 04:15:03 0000-00-00 00:00:00 2019 0 0 12 str. iss. 20, art. 3399 Vol. 12 17.
