Enzymatic hydrolysis of biomasses having a high dry matter (dm) content

A process for liquefaction and saccharification of polysaccharide containing biomasses comprising lignocellulosic and biomass, characterized in that said biomass is subjected to combined enzymatic hydrolysis using at least one cellulase and mixing with a free fall mixer such as a drum mixer or a tumble mixer providing mechanical processing and / or degradation of the biomass so that, in the process, biomass and saharifikuje melts to a liquid suitable for further processing such as fermentation, wherein the biomass has a dry matter content of between 20% and 40% at the start of the mixing / hidrolize.Prijava contains 15 claims.
