  1. Monosaccharide yields in g/kg total original dry matter, obtained directly as a result of different pretreatment combinations (pH, temperature (T), and time (t)) in the experimental design sets of acid (experiments 1-15) and alkaline (experiments 16-30) pretreatments. CP = center point (n = 3) given as average ± SD. The experiments were performed in a completely randomized manner.
