Ethanol production from lignocelluloses by encapsulated and flocculating yeast

Encapsulation and flocculation of fermenting yeast greatly improves the major factors in fermentation performance in ligocellulose hydrolyzates: ethanol yield, production rate, and sugar conversion.

This project aims to further improve the fermentation performance of encapsulated and flocculating yeast systems, and to enable conversion between lab and industry, by:

  • improving the encapsulation processes to achieve long-term robust cultivation of lignocellulose hydrolyzates a minimum cost
  • clarifying the cellular mechanisms leading to improved tolerance, yields, production rates and sugar conversion, by a detailed physiiological study of encapsulated and flocculating yeast in hydrolyzates
  • simulating the entire process, optimizing the process regarding the energy requirement, and performing an economical evaluation.
