Abstract
The amylolytic enzyme production byRhizopus oryzae NRRL 395 grown on different agricultural commodities was datermined. The mould produced much higher enzyme activity from barley, corn, bats, and rice than from cassava. The optimal temperature for enzyme production was 30°C. Neutralization with CaCO3 greatly enhanced the rate of enzyme production. Nitrogen supplementation of cassava resulted in higher enzyme yields.
Résumé
On a déterminé la production d'enzymes amyloytiques parRhizopus oryzae NRRL 395. cultivé sur différents produits agricoies. La moisissure produit une activité enzymatique plus élevée à partir du malt. du maïs, de l'avoine et du riz qu'á partir du manioc. La température optimale pour la production d'enzyme est de 30°C. La neutralisation par al CaCO2 augmente fortement la vitesse de production de l'enzyme. L'ajout d'azote au manioc résulte en un accroissement du rendement enzymatique.
