enzymatic hydrolysis process comprising the addition of vinasse as buffering agent of the lignocellulosic plant biomass-containing reaction medium

摘要

"use of vinasse in the saccharification process of lignocellulosic biomass". The present invention relates to the use of vinasse in the saccharification / fermentation process of lignocellulosic biomass, regardless of how they appear and regardless of the destination that will be given to the final hydrolyzed broth obtained. More specifically, the present invention describes the beneficial effect that vinasse confers on the saccharification process of lignocellulosic biomass, since it has, among other characteristics, the ability to buffer the reaction medium, especially when such a process occurs by enzymatic route, but not limited to it, regardless of the type of biomass being used and the type of pretreatment to which it was subjected. The present invention further relates to fermentative processes, such as ethanol production, comprising the use of vinasse as a source of nutrients such as nitrogen (n) for the growth of microorganisms, but not limited thereto. The present invention is situated in the field of chemical engineering.
