Abstract
Penicillium sp X−1 isolated from decayed raw corn produced high level of rawstarchdigesting glucoamylase RSDG under solid state fermentation SSF Maximum enzyme yield of 3062 U g−1 dry mouldy bran DMB was obtained after 36 h of culture upon optimized production The enzyme could hydrolyse both small and large granule starches but did not adsorb on raw starch The enzyme exhibited maximum activity at 65°C and pH 65 which provided an opportunity of synergism with αamylase It significantly hydrolysed 15 w/v raw corn starch slurry in synergism with the commercial αamylase and a degree of hydrolysis of 924 was obtained after 2 h of incubation
