Patent ID: 8017373

Claim:
A cellulase enzyme mixture comprising a primary cellulase mixture of CBH1 and CBH2 cellobiohydrolases and EG1 and EG2 endoglucanases, said CBH1 and CBH2 cellobiohydrolases being present at greater than or equal to 55% and less than 65% of the primary cellulase mixture, said CBH2 being present at a fraction relative to CBH1 and CBH2 cellobiohydrolases as defined by f C2 and said EG2 being present at a fraction relative to the EG1 and EG2 endoglucanases as defined by f E2 , wherein said f C2 is greater than or equal to 0.35 and less than 0.55, and (i) when said f C2 value is greater than or equal to 0.35 and less than 0.45, said f E2 value is greater than or equal to 0.15 and less than 0.35; and (ii) when said f C2 value is greater than or equal to 0.45 and less than 0.55, said f E2 value is greater than or equal to 0.15 and less than 0.25, or greater than or equal to 0.35 and less than 0.45.
