PROCESS FOR THE PRODUCTION OF OLIGOSACCHARIDES FROM LIGNOCELLULOSIC 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. |

1. A process for the production of oligosaccharides from lignocellulosic biomass, comprising at least the following steps:
a) pre-treating the biomass in a pre-treatment reactor in order to provide an effluent containing a pre-treated substrate; b) carrying out an enzymatic hydrolysis of the pre-treated substrate contained in the effluent obtained from step a) in a reactor, in the presence of cellulases in a manner such that a hydrolysate containing glucose, cellulases and water is produced; c) removing at least a portion of the hydrolysate obtained from step b) comprising a liquid fraction; d) reducing the water content of said portion of the hydrolysate removed in step c) in a manner such that the liquid fraction of the hydrolysate has a water content of less than 65% by weight of water with respect to the total weight of the liquid fraction of the hydrolysate; e) incubating the hydrolysate obtained 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. |
