<P><B>Abstract</B></P> <P>Quantitative analysis of enzyme adsorption and hydrolysis were performed for sieve-based grinding corn stover (SGCS) and ultrafine grinding corn stover (UGCS) <ce:cross-ref refid='fn1'> <SUP>1</SUP> </ce:cross-ref> with different enzyme consumptions. The UGCS presented significantly higher enzyme adsorption quantity (5.15mg/g for UGCS, 1.33mg/g for SGCS), higher glucose yield (49.75% for UGCS, 28.75% for SGCS) under 20FPU/g and higher binding enzyme proportion (41.32% for UGCS, 10.64% for SGCS under 5FPU/g) which can be attributed to the more accessible microstructure properties. The relationship between enzyme adsorption and hydrolytic production was directly proportional for SGCS (<I>GY</I> <SUB>1</SUB> =21.04× <I>AQ</I> <SUB>1</SUB> +1.86 (<I>R</I> <SUP>2</SUP> =0.95)) while was exponential for UGCS (<I>GY</I> <SUB>2</SUB> =49.42×(1− <I>e</I> <SUP>−0.57×AQ</SUP> <SUB>2</SUB>) (<I>R</I> <SUP>2</SUP> =0.99)), <ce:cross-ref refid='fn2'> <SUP>2</SUP> </ce:cross-ref> indicating that overmuch enzyme consumption was not advisable for UGCS at economical aspect.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Ultrafine grinding is efficient in changing the microstructure properties. </LI> <LI> The quantitative analysis of enzyme adsorption and hydrolysis were presented. </LI> <LI> The enzyme adsorption was exponential to hydrolytic production for UGCS. </LI> <LI> The binding enzyme proportion was inversely proportional to enzyme consumption. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
