Ternary diagrams for optimization of mixtures of four commercial enzymes for release of glucose (Glc; (a) and (b)) or xylose (Xyl; (c) and (d)) from alkaline hydrogen peroxide (AHP)-pretreated ((a) and (c)) or ammonia fiber expansion (AFEX)-pretreated ((b) and (d)) corn stover. Glc and Xyl yield values indicate yield as a percentage of total measured monomeric Glc and Xyl content of the biomass. The data on which the ternary diagrams are based are from the same experiment shown in Table 1.
