Cell wall degrading enzymes produced by the phytopathogenic fungus verticillium tricorpus

Abstract EN

The growth of phytopathogenic fungus Verticil/ium tricorpus on 15 carbohydrate substrates was monitored to analyse the range of polysaccharide-d.egrading enzymes and gIucosidases production.

The secretion of endo and exo-enzymes, capable of degrading cellulosic, hemicellulosic and pectinolytic polysaccharides were observed during the course of the experiment.

Pectinolytic activities were produced constitutively on all the substrate tested., while cellulolytic enzymes were not induced in simple sugar (i.e., glucose or xylose) media.

Polysaccharide growth substrates and cellulase inducers increased all of the enzyme activities tested.
