Abstract
Penicillium oxalicum Curie et Thom produced an exo-polygalacturonase, an endo-polygalacturonase and an endo-pectate lyase. It also produced cellulase Cx, cellobiase, B-glucosidase, xylanase, galactanase and arabinanase in culture and in infected yam tissues. The exo-polygalacturonase was unstable. It has a molecular weight of about 38 000 daltons. The endopolygalacturonase and endo-pectate lyase had an optimal pH of 5.0 and 8.5 and an isoelectric point (pI) at pH 3.6 and 4.9 respectively. Molecular weights of both enzymes were about 28 500 and 30 000 daltons respectively. The end products of the reaction were oligogalacturonides and revealed that cellulose was degraded to glucose, with cellobiose as an intermediate product. The end products of the degradation of hemicelluloses were xylose, galactose and arabinose.
