Abstract
Filamentous fungi from soil were screened for their ability to produce amylases in semisolid and liquid media with wheat bran. A selected st rain identified as Aspergillus fumigatus Fresenius showed high enzymat ic activity for alpha-amylase and glucoamylase. The maximal yield of t hese amylases was obtained when lignocellulosic materials were the car bon sources. The optimal pH and temperature were 6.0 and 50-degrees-C, respectively, for both enzymes. Alpha-Amylase activity was more therm ostable than glucoamylase activity.
