Klebsiella pneumoniae AK mutant strain defective in 1,3-PD oxidoreductase activity (DhaT). The Escherichia coli yqhD homolog can replace the function of DhaT. The yqhD homolog restores propane-1,3-diol production and 1,3-PD oxidoreductase activity in the mutant Klebsiella pneumoniae strain defective in DhaT. Level of propane-1,3-diol production during batch fermentation in the recombinant strain is comparable to that of the parent strain |

Klebsiella pneumoniae mutant strain AK (dhaD and dhaK replaced with the lacZ promoter-apramycin resistance gene cassette, such that the lacZ promoter is inserted in front of dhaB) and mutant strain AR (deletion of the dhaR gene and replaced with the lacZ promoter-apramycin resistance gene cassette, defective in the oxidative branch and in the reductive branch due to the loss of the dhaT and orfWX). propane-1,3-diol is still produced at lower level in the mutant strains, even though dhaT is removed, thus a a putative oxidoreductase may catalyze the production of propane-1,3-diol at lower level compared to DhaT. Dramatic increase in the production of propane-1,3-diol in the recombinant strains harboring the plasmid pBR-dhaT or pBR-dhaT-orfWX, which contain dhaT. Amount of propane-1,3-diol produced is lower in the AK and AR strain, which is harboring pBR-dhaT-orfWX (5.2 g/l), than the corresponding Cu, which is harboring pBR-dhaT-orfWX (7.7 g/l). During fermentation, the production yield is higher in the AK strain (0.57 mol/mol) than the Cu strain (0.47 mol/mol) harboring pBR-dhaT-orfWX |

expression of the Clostridumm butyricum enzyme in Clostridium acetobutylicum strain DG1(pSPD5) leads to functional reduction of glycerol to 1,3-propanediol in a two-step process, the first step of glycerol reduction to 3-hydroxypropionaldehyde, which is then reduced to 1,3-propanediol, is performed by the B12-independent glycerol dehydratase |
