Abstract
The present application relates to reaction mixtures comprising biomass, a solid acid catalyst and cellulolytic enzymes or organisms expressing such enzymes for converting biomass to useful feedstocks and methods of forming products via fermentation using the said reaction mixture.
Claims15
A method of releasing saccharides from a biomass comprising the steps:
- a) pre-treating a biomass with a solid acid catalyst to form a solid acid catalyst mixture,
- b) forming an aqueous reaction mixture comprising the solid acid catalyst mixture of step a), and one or more cellulases and/or hemicellulase enzymes or mixtures thereof or an organism capable of expressing one or more cellulases and/or hemicellulase enzymes,
- wherein the solid acid catalyst is obtained from kaolin and the solid acid catalyst mixture is not purified prior to step b).
