The pretreatment of corn cob was carried out with different combinations of alkali at varying temperatures. The most effective pretreatment of corn cob was achieved with 1 % alkali at 50 A degrees C in 4 h. The crystallinity index (CrI) and specific surface area (SSA) of untreated corn cob was 39 % and 0.52 m(2)/g wherein after alkali pretreatment CrI decreased to 15 % and SSA increased to 3.32 m(2)/g. The fungal organism was identified as Penicillium pinophilum on the basis of ITS sequence. At 5 % substrate concentration using a complete cellulase from Penicillium pinophilum the hydrolysis of untreated corn cob with 5, 10 and 20 FPU/g enzyme loadings were 11 %, 13 % and 16 %, whereas after alkali treatment the hydrolysis increased to 78 %, 90 % and 100 %, respectively. Further hydrolytic potential of commercial cellulases viz. Accellerase (TM) 1,000, Palkofeel-30 and Palkocel-40 were investigated under similar conditions.</p>10aCorn cob10aCrystallinity index10aEnzymatic hydrolysis10aPenicillium pinophilum10aSpecific surface area1 aSahare, Padmavati1 aSingh, Rajkumar1 aLaxman, Ryali, Seeta1 aRao, Mala  uhttps://library.ncl.res.in/content/effect-alkali-pretreatment-structural-properties-and-enzymatic-hydrolysis-corn-cob-0
