3-Hydroxypropionaldehyde (3HPA) was produced from glycerol by Lactobacillus reuteri through a single enzyme catalyzed reaction. Complex formation with sodium bisulfite was studied and used for in situ capture of 3HPA in a fed-batch biotransformation, with prolonged bioactivity of the cells for at least 18 h and more than double yield of 3HPA than the process without bisulfite. The ratio of 3HPA to other products was also doubled.
