  • Serinol production in glycerol catabolism deficient strains
    Patent number: 9109240
    Abstract: The invention is about E. coli host cells which are capable to convert glycerol to serinol. Furthermore, a process for producing serinol is disclosed, which comprises culturing E. coli host cells inactive for triosephosphate isomerase and active for dihydroxyacetone phosphate aminotransferase to convert glycerol to serinol, induction of conversion from glycerol to serinol by adding at least glycerol to the cell culture, and isolating serinol from the cell culture.
    Type: Grant
    Filed: September 5, 2013
    Date of Patent: August 18, 2015
    Assignees: BASF SE, Westfaelische Wilhelms Universitaet Muenster
