摘要： The present invention provides a method for decreasing the fermentation inhibition in a process for producing a target chemical from a pretreated cellulosic material, the process comprising enzymatic hydrolysis of the pretreated cellulosic material and fermentation of hydrolysed material, wherein the fermentation inhibitory properties of the material subjected to fermentation is decreased by an addition of at least one reducing agent to the pretreated material or hydrolysed material. Moreover, the present invention provides the use of dithionite for decreasing the fermentation inhibitory properties of a material being subjected to simultaneous enzymatic hydrolysis and fermentation.
