Isolate ranking based on RPI. The relative performance index (RPI) concept was applied to the performance results of the secondary screen in order to rank 33 isolates within each hydrolyzate type based on xylose uptake rate and ethanol yield per sugar supplied. (A) The relative ranking of any given isolate depended on the hydrolyzate type (P < 0.001): SGH-N1 (blue bars), SGH-N2 (red bars), and AFEX CSH (green bars). (B) The overall RPI calculated across all hydrolyzate types (light blue bars) indicated superior strains with most robust performance across different hydrolyzate conditions.
