METHOD FOR PRODUCING OLIGOSACCHARIDES FROM A LIGNOCELLULOSE BIOMASS

摘要

A process for producing oligosaccharides from lignocellulosic biomass, having the following steps: a) pre-treating the biomass in a pre-treatment reactor (1) in order to provide an effluent containing a pre-treated substrate; b) enzymatic hydrolysis of the pre-treated substrate contained in the effluent from step a) in a reactor, in the presence of cellulases such that a hydrolysate containing glucose, cellulases and water is produced; c) removing at least a portion of the hydrolysate from step b) comprising a liquid fraction; d) reducing the water content of said portion of the hydrolysate in step c) such that the liquid fraction of the hydrolysate has a water content of less than 65% by weight with respect to the total weight of the liquid fraction; e) incubating the hydrolysate from step d) at a temperature in the range 40° C. to 70° C. for the time necessary to produce an effluent enriched in oligosaccharides.
