Abstract
The present invention concerns a new method for the production of 1,3-propanediol comprising culturing a recombinant microorganism converting glycerol into 1,3-propanediol and overexpressing the hcpR and/or frdX gene on a medium comprising glycerine. A recombinant microorganism for the production of 1,3 propanediol from glycerol, wherein said microorganism converts glycerol into 1,3-propanediol and 10 overexpresses the hcpR and/or the frdX gene.
