Production of amylases by some aspergillus and fusarium species isolated from waste corncobs in Keffi, Nigeria

Amylases are important industrial enzymes that have wide applications ranging from conversion of starch to sugar syrups, the production cyclodextrins for pharmaceutical industry. This investigation aimed at amylases using Aspergillus and Fusarium species isolated waste-corncobs in Keffi Nigeria. Standard microbiological methods were employed isolation identification fungal isolates. The yields produced by fungi isolates determined Spectrometry. rate was high location A, C D with 60% B 40%. percentage occurrence demonstrated carneus 40%, aculeatus flavus 20% while moniliforme 80% redolens result three aculeatus, found produce amylases. locations C3, D1 D2 0.018mg/ml, 0.018mg/ml 0.016mg/ml respectively. Similarly, A1 B2 0.021mg/ml 0.012mg/ml A3, C1 C4 0.010mg/ml, 0.015mg/ml Result effect (temperature, pH fermentation time) Whereas highest amount F monliforme 28 OC. 5.0 best optima studied A.
