Customer application: Enzymatic degradation of bioplastics

Bioplastics are polymers that are produced on the basis of renewable resources. An example of this is poly(3-hydroxyalkanoate) (PHA). The latter is formed by bacteria and acts as a carbon reservoir for them. They can degrade it again later as required with the aid of enzymes, the PHA depolymerases. The work group headed by Prof. Dr. Jendrossek at the Institute for Microbiology at the University of Stuttgart is investigating the depolymerization in cells. Titration is used to measure enzyme activity.
