| Abstract:A kind of green antibacterial paper was manufactured by coating glucose oxidase and lysozyme on the paper. Its antimicrobial effect was evaluated through antibacterial annulus test and SEM. The best antimicrobial performance of using glucose oxidase only could be obtained when pH value was 6.5 and enzyme activity was 4000~6000 U/g (on oven dry pulp). And the best antimicrobial effect of using lsozymein only could be obtained when pH value was 5.5 and enzyme activity was 5000~20000 U/g (on oven dry pulp). Antibacterial annulus test and TEM observation showed that the antimicrobial effect of using combined enzyme was better. When using combined enzyme the optimum condition was enzyme activities of 4000 U/g (on oven dry pulp) and 10000 U/g (on oven dry pulp) for glucose oxidase and lysozymein respectively, and pH value was 6.0. |
