Abstract:
The invention relates to a process for the conversion of lignocellulose into an organic acid including an alkaline pretreatment step and a fermentation step, wherein liquid phase obtained in the fermentation step is recycled to the alkaline pretreatment step and/or the fermentation step. Organic acid is recovered as its magnesium of calcium salt from solid phase obtained in the fermentation step.
