Continuous fermentation with yeast cells immobilized on wood
chips suggests that it is a suitable carrier for cell immobilization in
ethanol fermentation. A high ethanol productivity of 15.88 g/l h
using S. cerevisiae strain suggests industrial feasibility of the column
fermentation. The column reactor was operated for nearly 25 days in
continuous flowmode and could have been operated longer at lower
dilution rates. This method has a strong potential of using C. forskohlii root hydrolysate as a substrate for bioethanol production, and could be undertaken by industrial houses processing the
said roots for extraction of forskolin.
