Project
Paper Recycling with Enzymes
Enzymes have already been shown to efficiently deink paper. However, application of enzymes in industry requires a highly optimised procedure. For this, it would be ideal to develop a cheap and easy to use system based on continuous secretion of various enzymes, which could be then used to test their deinking efficiency.
Our approach relies on gene expression in Bacillus subtilis, as this species naturally secretes large amounts of proteins into its surrounding. Using B. Subtilis allows us to purify or even use our enzymes directly from the supernatant. We managed to developed a expression plasmid for B. subtilis for the iGEM parts registry, which allows replication in Escherichia coli, as well as in B. subtilis. Last but not least, bacterial supernatants containing the expressed enzymes have been tested in the deinking process.
We aim to revolutionize paper recycling by integrating all of the above aspects into one procedure that is simple enough to be applied not only in centralized recycling facilities, but also for implementation on a smaller scale. This would dramatically reduce the distance paper waste needs to be transported, thereby reducing the carbon footprint of the entire process. Our system is the prerequisite to improve enzymatic deinking to a level where it is not only industrial feasible, but outperforms chemical deinking on this scale.

In order to guarantee the efficiency of our own secreted enzymes and find optimum environment in our project set up for the own enzymes and bought ones, a functional enzyme assay is necessary.
