We have demonstrated the potential use of TSC for repeated batch and continuous ethanol fermentation. The immobilization of S. cerevisiae M30 was performed by adsorption on TSC. Many advantages, such as reusability, altered mechanical strength, cell regeneration and high immobilized yield, were achieved and resulted in stable operation with a high ethanol production and high biomass density. A comparative study of repeated batch fermentation showed that the TSC-cell system was more stable than the conventional free-cell system. A maximum ethanol productivity of 19.0 g/(L h) was obtained at a dilution rate of 0.36 h−1 with an average immobilized yield of 87.0% during the continuous fermentation of blackstrap molasses in a 1 L packed bed reactor. Since the applications of immobilized cells on TSC shows the potential benefits for ethanol production, the further investigation of the continuous ethanol fermentations using immobilized yeast cells on TSC in a pilot scale is ongoing in order to determine the applicability of commercial practices.
