Abstract
Functionalized substrate materials, for example inorganic particles and/or synthetic polymeric particles, are used to enhance bioprocesses such as saccharification and fermentation.
Claims18
A fermentation method comprising:
- (a) functionalizing inorganic fibers by irradiating the fibers with ionizing radiation and quenching the irradiated fibers;
- and
- (b) contacting a low molecular weight sugar with the functionalized inorganic fibers and a fermenting microorganism immobilized on the fibers, within a medium, for a period of time and under suitable fermentation conditions to convert the low molecular weight sugar to a fermentation product, whereby the immobilization occurs as a result of interaction between functional groups on the functionalized fibers and functional groups on the microorganism.
