  1. Values presented as ±SD. There was an overall significant difference in % recovery of glucose and ASR (acid soluble residue, ash, and protein) in the recovered solids, F(3,12) = 5.01, P < 0.03 and F(3,12) = 4.07, P < 0.05. There was a non-significant difference in the % xylose and lignin recovery in the solids, F(3,12) = 3.89, P = 0.06 and F(3,12) = 0.44, P = 0.73. Composition of recovered solids after 70 °C 5 h [C2C1im][OAc] pretreatment. Glucose, xylose, and lignin were reported as the relative composition of recovered biomass. Pretreatment was done at 10 % (w/w) biomass. There was an overall significant difference in % total solids and xylose, F(3,12) = 11.52, P < 0.005, F(3,12) = 8.48, P < 0.01. There was no overall significance for the % composition glucose or lignin F(3,12) =2.57, P = 0.13 and F(3,12) = 3.1, P = 0.09. ANOVA with a Tukey’s HSD post-hoc test was used to determine overall statistics, and results of the comparison to WT from the post-hoc test are shown in the table
