Performance of a continuous bioreactor with immobilized yeast cells in the ethanol fermentation of molasses-stillage medium

  • Published:
Biotechnology Letters Aims and scope Submit manuscript

Summary

It is feasible to produce ethanol by continuous fermentation of molasses-stillage medium, without any supplementation, employing calcium alginate immobilized cells of Saccharomyces cerevisiae. High flow rates generated high values for the productivity; however, the percent substrate conversion decreases with the dilution rate.
