Fig. 4From: Evaluating polymer interplay after hot water pretreatment to investigate maize stem internode recalcitranceChanges in the total adsorbed dye and in the DY11/DB1 ratio of raw and pretreated samples. The total adsorbed dye are represented by bars with left axis and DY11/DB1 ratio by plots with the right axis. The M7 values are represented in white and M9 samples in grayBack to article page
