Abstract

An enzyme mixture for the enzymatic hydrolysis of a pretreated lignocellulosic feedstock to soluble sugars is provided. Also provided is a process for hydrolyzing a pretreated lignocellulosic feedstock with an enzyme mixture. The enzymatic hydrolysis comprises adding a cellulase enzyme mixture to a pretreated lignocellulosic feedstock. The cellulase enzyme mixture comprises a primary cellulase mixture of CBH1 and CBH2, and EG1 and EG2. The CBH1 and CBH2 being present at greater than or equal to 55% and less than 85% of the primary cellulase mixture. Furthermore, CBH2 is present at a fraction relative to CBH1 and CBH2, and EG2 is present at a fraction relative to the EG1 and EG2.
