Abstract: The present disclosure relates to single and/or multi-stage, biological processes and systems for converting C5, C6, and/or disaccharide carbon sources to desirable products including monoethylene glycol (MEG) and one or more three-carbon compounds such as acetone, isopropanol or propene. The MEG and one or more three-carbon compounds described herein are useful as starting material for production of other compounds or as end products for industrial and household use. The disclosure further relates to the processes carrying out fermentations of substrates in a single phase bioreactor or in a multiphase bioreactor comprising growth and production phases. Additionally, the processes and systems described herein result in high productivity and yield of the desired products due to intermittent or continuous removal of products to avoid inhibitory effects.
