Utilization of Waste Paper for Enzyme Production 

Do you know waste paper could be utilized for enzyme production

Researchers at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) have recently found that waste paper could be efficiently utilized for enzyme production by Trichoderma longiflorum. The study was published in Journal of Cleaner Production

Cellulase is widely used in biofuel, food, papermaking, textile washing, medicine, animal feed and agricultural waste treatment. However, the high production cost of enzyme remains a major challenge for its further industrial applications

Waste paper has the great application potential due to its richness in cellulose, low cost and high abundance. Thus, to produce cellulase and xylanase by utilizing waste paper not only reduces the cost of enzyme production, but also achieves the efficient utilization of waste paper resources

In the experiment, the researchers used waste office paper, corrugated board, magazine paper and tissue paper for enzyme production by T.longiflorum LC-M4. By studying the structural characterization of waste paper, they revealed that the cellulose is the main component in different waste paper, and the fillers such as calcium carbonate can provide nutrient elements for microbial growth and enzyme synthesis

These findings obtained from the study revealed the feasibility of utilizing the waste paper as an inductive carbon source for enzyme production, which is of great benefit both for the economy and environment
