Protopectinases (PPases) constitute a heterogeneous group of enzymes able to release soluble pectin from insoluble protopectin in plant tissues. Geotrichum klebahnii (ATCC 42397), a yeast-like fungus, produces PPase-SE, an extracellular enzyme with endopolygalacturonase (EC 3.2.1.15) activity. The potential use of PPase-SE on pectin extraction and maceration of plant tissues has been reported. Here, it was studied the capacity of G. klebahnii to produce PPase-SE in fed-batch system at different flow profiles.
