Enzyme Treatment Increases Acid Groups

چکیده
Agenda 2020 has identified the need to improve the quality of recovered fiber. This project addresses this challenge with the use oxidative enzymes, such as laccase and soybean peroxidase/hydrogen peroxide, that increase the fiber charge of recycled fibers. By increasing the number of surface carboxylic acid groups on recycle fiber, this treatment will improve paper strength. In addition, oxidative enzyme treatments can also enhance brightness and color removal.

متن کاملEvaluation of Different Functionalized CNTs for Development of Choline Amperometric Biosensor
Choline oxidase (ChOx) was chosen as a model enzyme for evaluating the performance of CNTs’ functional groups for development of enzyme electrodes. CNTs were functionalized with carboxylic acid, amine or amide groups. Carboxylic acid, amine and amide functionalized CNTs were obtained by acid treatment, ethylenediamine or tetraethylenepentamine chemically modification and ammonia plasma treatmen...
