Process scheme of polygalacturonic acid (PolyGalA) degradation. U. maydis produces pectinases that degrade dissolved PolyGalA to monomeric galacturonic acid (GalA). GalA and oxygen are consumed in a fixed stoichiometric ratio while carbon dioxide is released. Oxygen consumption and carbon dioxide release are measured online. This concept enables the investigation of PolyGalA degradation by pectinolytic enzymes based on online monitoring of the metabolic activity
