title: Antibacterial activity of konjac glucomannan/chitosan blend films and their irradiation-modified counterparts.
abstract: Antibacterial activity of glucomannan/chitosan (KGM/CHI) blend films and their irradiation-modified counterparts were tested. The KGM/CHI blend films after irradiation showed good antibacterial effects against Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus. Antibacterial activity of the blend films increased with the increase of the content of chitosan. After different dose irradiation, there was no obvious change in the antibacterial effects against St. aureus of the blend films, but the antibacterial effects against E. coli and P. aeruginosa increased significantly.
