Fig. 3From: Water-soluble saponins accumulate in drought-stressed switchgrass and may inhibit yeast growth during bioethanol productionGlucan conversion (A) and glucose yield (B) for enzymatically hydrolyzed switchgrass after 72 h. Samples that do not share a letter on top of the bars are significantly different based on Tukey’s pairwise statistical comparison (⍺ = 0.05). In this statistical model, year and extraction solvent were nested within extraction timing with respect to AFEX pretreatment. Data points represent the average ± standard deviation (n = 3)Back to article page
