The effects of moisture level, particle size and inoculum concentration on enzyme synthesis from R chrysogenum were investigated. Optimal moisture levels of substrates were 75, 65, 65 and 55% for CL, WS, WB and RS substrates, respectively. Optimal particle size and inoculum concentration for the production of alpha-amylase were: >1 mm, 20%; >1 mm, 20%; 1 mm, 20% and >1 mm, 30% for CL, WS, WB and RS, respectively WB showed the highest enzyme production with 160 U/mL under optimum conditions. The other enzyme activities were 28, 49 and 45 U/mL using CL, RS and WS, respectively.eninfo:eu-repo/semantics/closedAccessAlpha-AmylasePenicillium ChrysogenumSolid-State FermentationBacillus-SubtilisHydrolysisStarchArticle454439442Q3WOS:0002516826000152-s2.0-40749093717Q2
