iFermenter project aims to recover high value compounds from sugar residuals, and to turn fermentation processes converting these residual to antimicrobials cost effective. The project has a potential to contribute to the global bio-based market by exploiting residual sugars (€0.5 / kg) to recover their high value compounds (€40-200 /kg) and, with the remaining sugars, produce several high value antimicrobials (€50- 150 /kg) by intelligent fermentation. These products have substantial economical and social impact. Our strains and technology will solve some of the major difficulties in up-scaling.
