Abstract
Filamentous fungi from soil were screened for their ability to produce amylases in semisolid and liquid media with wheat bran. A selected strain identified as Aspergillus fumigatus Fresenius showed high enzymatic activity for α-amylase and glucoamylase. The maximal yield of these amylases was obtained when lignocellulosic materials were the carbon sources. The optimal pH and temperature were 6.0 and 50 °C, respectively, for both enzymes. α-Amylase activity was more thermostable than glucoamylase activity.Key words: amylolitic fungi, α-amylase, glucoamylase, Aspergillus fumigatus.
