INTEGRATED PROCESS FOR THE PRODUCTION OF CELLULOSIC ETHANOL, LIGNIN AND THEIR DERIVATIVES FOR THE PRODUCTION OF YEAR AND COPRODUCTS BIOMASS OBTAINED FROM HEMICELLULOSTIC SUBSTRATES

摘要

integrated process for the production of cellulosic ethanol, lignin and their derivatives for the production of yeast and co-products biomass obtained from hemicellulosic substrates. The present patent application describes the process for the production of cell biomass and co-products from the use of yeasts capable of assimilating and metabolizing hemicelluloses pentoses from sugarcane bagasse hydrolyzate, which is now used as a protein source. ; thus conferring a new use for this fraction, which in general ends up not being used for the production of second generation ethanol.
