The results showed excellent sugar and lignin mass balances for pretreatment, and precipitated lignin in the hydrolysate obtained at 15 g/L of FA decreased to 0.31 g/100 g straw compared to autohydrolysis (no FA) of 0.94 g/100 g straw. The average molecular weight of precipitated lignin decreased from 1970 g/mole for autohydrolysis to 710 g/mole at 15 g/L of FA. The monomeric sugar yield during pretreatment improved from 3.83 g/100 g for autohydrolysis to 23.5 g/100 g at 15 g/L FA.en10.1016/j.indcrop.2017.12.026info:eu-repo/semantics/closedAccessAutohydrolysisFormic acidLignin precipitatesPretreatmentWheat strawArticle112320326WOS:000425561900040Q1Q1
