Rogaia M.G. Al- Gashgari

Abstract: At 28oC for 14 days 12 species belonging to 3 genera were isolated from 26 kinds of juice. These were identified as Curvularia lunata, Mycelia sterilia, Aspergillus represented by A. flavus, A. olivino viridi, A. parasiticus, A. viridi nutans, A. terreus, A. cervinus, A. ustus, A. nidulans A. fumigatus and A. niger, the latter being predominant. But, no growth at 45oC for 14 days. About 74% of 50 samples could produce pectinase enzyme with different degrees. From the positive isolates 38% exhibited the highest pectinase production and these related to A. flavus, A. fumigatus, A. niger, A. parasiticus and A. terreus. Whereas, the remaining positive isolates were moderate and weak producers.
