First Claim
Patent Images
1. A process for producing a bioproduct, comprising:
- (i) hydrolyzing a carbohydrate-containing feedstock upstream from a bioreactor that comprises a microbial growth medium and a microorganism that is immobilized on a support in the bioreactor, wherein the carbohydrate-containing feedstock is deconstructed prior to hydrolysis; and
(ii) feeding a resulting hydrolyzed feedstock to the bioreactor,wherein the hydrolyzed feedstock comprises carbohydrate molecules that serve as a carbon source for growth of the microorganism,wherein the microorganism ferments the hydrolyzed feedstock to produce the bioproduct, andwherein the hydrolysis of the feedstock, feeding of the hydrolyzed feedstock to the bioreactor, and production of the bioproduct are continuous.

Abstract
Processes and systems for production of bioproducts such as biofuels are provided. The bioproduct production processes and systems utilize pretreatment of a carbohydrate-containing feedstock to produce soluble sugar molecules and continuous conversion of the pretreated feedstock to a bioproduct by an immobilized fermenting microorganism.
