| dc.description.abstract | In this study, two strains of fungi Aspergillus unguis and Penicillium citrinum isolated and identified from weasel coffee in Lam Dong province were used for optimization of culture conditions for pectinase production in SSF. At the room temperature (27-300C) and initial cell concentration was 108 spores/ml, the highest pectinase activity was achieved when Aspergillus unguis was grown during 78 hours with 90% rice bran used as carbon source, 1% ammonium sulfate used as nitrogen source, 9% rice husk, 4% pectin, 1% MnSO4.H2O and 45% moisture content. On the other hand, under the same temperature (27-300C), the highest pectinase activity was achieved in SSF from Penicillium citrinum with 90% rice bran, 1% ammonium sulfate, 9% rice husk, 2% pectin, 1% MnSO4.H2O and 50% moisture content during 60 hours of growth.
