Isolates in italics are considered superior based on high overall RPI across hydrolyzate types, low relative standard deviation (Rel. s), and/or exceedingly high RPI on at least one hydrolyzate type as seen in Figure 10A.
Strains are ranked based on ethanol yield and xylose uptake rate in screens on dilute acid-pretreated switchgrass enzyme hydrolyzates with two different nutrient supplements (SGH-N1 and SGH-N2) or over all three hydrolyzates including AFEX-pretreated corn stover enzyme hydrolyzates.
