Fermentation of C6 carbohydrates from triticale straw hemicellulosic fraction as pretreatment for xylose purification

•Isolation of triticale constitutive macromolecules was achieved using FIRSST treatment.•One-step and two-step FIRSST treatment were compared.•Two-step FIRSST treatment allowed the direct recovery of relatively pure hemicelluloses.•C6 sugars from the hemicellulosic broth were successfully fermented...
