The systems and methods involve co-fermentation of sugars and gaseous substrates for alcohol, ketone, and/or organic acid production. The systems and methods may include biocatalytically converting at least one sugar substrate into at least one of alcohol, at least one ketone, and/or at least one organic acid. The systems and methods may further include biocatalytically converting gases that comprise CO2 and H2 to at least one alcohol and/or at least one organic acid, thereby adding extra revenue to biorefineries.application/pdf18 pagesText11180779C12P 7/065C12M 21/12C12M 23/58C12N 1/20C12N 1/22C12P 7/16C12P 7/28C12P 7/52C12P 7/54C12P 7/04C12P 39/00C12R 2001/145C12P 2203/00Y02E 50/10
