<P>The effects of catabolite repression of initial glucose on the synthesis of α-amylase from <I>Penicillium chrysogenum</I> and <I>Penicillium griseofulvum</I> were investigated under solid-state fermentation (SSF) and submerged fermentation (SmF) systems. The results obtained from either fermentation were compared with each other. In the SmF system, initial glucose concentration above 10 mg/mL completely repressed the production of α-amylase from <I>P. chrysogenum</I> and <I>P</I>. <I>griseofulvum</I>. However, the repression in the SSF system was not complete, even when the glucose level was raised to 160 mg/g.</P>
