Summary

Cryptococcus albidus var. albidus, strain IMAT-4735, grown on suitably treated oil-mill vegetation waters produced pectic enzyme. Growth and enzyme production were favoured by addition of calathide residues from sunflower cultivation, a low-cost pectic material, to the vegetation waters. Ultrafiltration of the centrifuged fermentation broth made it possible to almost completely recover the enzyme activity produced. The enzyme concentrate from ultrafiltration was directly reused in the me chanical extraction of olive oil.
