Duisburg/Leipzig. In future, polymethyl methacrylate (PMMA for short) - better known as acrylic glass - could be made from natural raw materials such as sugars, alcohols or fatty acids. PMMA is manufactured by polymerising methyl methacrylate (MMA). In a bacterial strain, scientists at the University of Duisburg-Essen and the Helmholtz Centre for Environmental Research (UFZ) have found an enzyme which could be used for the biotechnological production of a precursor of MMA. Compared with the previous chemical production process, a biotechnological process is far more environmentally friendly.

Dr Thore Rohwerder has been nominated as one of three candidates for the European Evonik research award for his discovery. The competition is overseen by Dr Arend Oetker, president of the Stifterverband fr die Deutsche Wissenschaft (Association of Donors to German Science). The aim of the award is to encourage young researchers to risk taking the step from the laboratory into business. The topic of the 2008 Evonik research award is "White Biotechnology" (industrial biotechnology). The Science-to-Business Award worth EUR 100,000 was given to Dr. Paul Dalby from the University College London on November 12th in Berlin. Dalby's method for combining enzymes and customizing them for new tasks convinced the international jury.

The newly enzyme discovered by Dr. Thore Rohwerder und Dr. Roland H. Mller, called 2-hydroxyisobutyryl-CoA mutase, makes it possible to turn a linear C4 carbon structure into a branched one. Compounds of this type are precursors of MMA. Parent compounds may of course include intermediate products from the petrochemical industry. The revolutionary aspect, however, is that this enzyme, integrated into metabolically appropriate microorganisms, can also transform sugars and other natural compounds into
