Chromatographic profiles for 1,3PDO, 3HP and AA production via the combined three-step process. a 3HP and 1,3PDO produced from glycerol using resting cells of L. reuteri DSM 20016. b 3HP produced from bioconversion of 1,3PDO in mixture with 3HP using resting cells of G. oxydans. c AA produced by catalytic dehydration of the resulting 3HP using TiO2 (3HP and AA peaks were confirmed using UV detection at 215Â nm)
