Pectic Enzymes of the Fungus Byssochlamys fulva

Beavan and Brown1 investigated the pectic enzymes of the fungus Byssochlamys fulva and were unable to detect pectin-esterase or polygalacturonase, although protopectinase was shown to be present by its disintegrating action on disks of potato tuber. They concluded that B. fulva elaborated a disaggregating enzyme which reduced the molecular size of pectin, without the production of galacturonic acid, on the lines suggested by Kertesz2.
