    Determination of Cellulase Activity of Phleobiopsis Sp., Penicillium Shearii, Phacoacremonium Rubrigenum and Clonostachys Sp. Cultured On Various Plant Biomass Substrates
    (Kenyatta University, 2023-07) Jobita, Christine Ichia
    Cellulose being the most accessible organic compound in nature can be broken down to produce biofuels. The enzyme that is responsible for breaking down cellulose into glucose is referred to as cellulase. This study was aimed at isolation, identification and characterization of cellulase producing fungi from a decaying tree trunk, determining the effect of incubation time on cellulase production using untreated maize cobs, rice husks and sugarcane bagasse by solid state fermentation and determining the effect of pretreated maize cobs, sugarcane bagasse and rice husks as Penicillium shearii produced the highest total cellulase activity (FPase) and exoglucanase enzymes at 36.1+£0.14IU/ml and 22.9+0.14IU/ml respectively. Phaeoacremonium rubrigenum produced the highest endoglucanase activity at by Phlebiopsis sp. at 6.17+0.041U/; h 5 sp. 6. i ‘ml and 25.1+0.611U/ml, respectivel gI}l0051dase activity Wwas - highest in Phlebiopsis sp. when maize cobs wgre ;l)::trye'atfd .
