Lignin containing polyethylene films with antibacterial activity
Original language description
In the presented investigation we compare the antibacterial effectiveness of Björkman lignin to Bronopol, Benzalkonium chloride,Chlorhexidine and Silver nitrate. Polyethylene films with 2 wt% of antibacterial additives were prepared by solution casting technique. Antibacterial activity against Escherichia coli and Staphylococcus aureus was determined by agar diffusion test. All tested antibacterial additives proved antimicrobial activity determined by the means of inhibition growth zones in millimeters.The effect of Björkman beech lignin is comparable with Bronopol and Chlorhexidine. The highest antibacterial activity was recorded for Benzalkonium chloride. These results indicate that the nano-Björkman lignin (particle size up to 60 nm) isolated frombeech wood has great potential as antibacterial agent for polymer blends. Moreover, stressstrain analyses of the prepared films showed that the addition of 2 wt% nano-Björkman lignin did not alter the mechanical properties of polyethylene
