Table 3 ANOVA of the total sugar yield (g/g) of the sorghum feedstocks from ASE350 experiments

From: Improved sugar yields from biomass sorghum feedstocks: comparing low-lignin mutants and pretreatment chemistries

  1. Only experimental data from pretreatment reactor temperatures of 150 and 160 °C are included in this analysis, since higher pretreatment temperatures caused excessive degradation of solubilized xylose (see text)
