Extractive bioconversion in aqueous two-phase systems. A model study on the conversion of cellulose to ethanol

  • Published:
Biotechnology Letters Aims and scope Submit manuscript


Aqueous two-phase systems composed of dextran and poly (ethylene glycol) have been successfully used for glucose fermentation, cellulose hydrolysis and bioconversion of cellulose to ethanol. The biocatalysts are confined in the bottom phase whereas the products are extracted by the top phase.
