An immobilized cell microchannel bioreactor was designed to test continuous fermentation.
The fermentation set-up included a bottom hydrophilic quartz channel to immobilize cells
using 0.4 wt% polyethyleneimine and a top channel designed to continuously remove
metabolically generated carbon dioxide using hydrophobic polypropylene. To evaluate
fermentation characteristics of immobilized cells, ethanol fermentation was carried out using
Saccharomyces cerevisiae and Pichia stipitis. The immobilized cell microchannel bioreactor …
