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 alpha-amylase from P. chrysogenum and P. griseofulvum. However, the repression in the SSF system was not complete, even when the glucose level was raised to 160 mg/g.en10.1080/13102818.2014.901670info:eu-repo/semantics/openAccessPenicilliumCatabolite RepressionAlpha-AmylaseSolid-State FermentationSubmerged FermentationXylanaseOptimizationRepressionResistantArticle28196101Q4WOS:0003380158000142-s2.0-8490591910026019493Q3
