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.
