Abstract
The invention concerns a method for preparing 1,3-propanediol from a carbon-containing substance, said method comprising a step which consists in culturing a recombinant micro-organism not producing coenzyme B12 in the absence of coenzyme B12 or one of its precursors. The invention also concerns a nucleic acid coding for a glycerol dehydratase whereof the catalytic activity is independent of the presence of coenzyme B12 or one of its precursors and a nucleic acid coding for a 1,3-propanol dehydrogenase intervening in the synthesis of 1,3-propanediol. The invention further concerns recombinant vectors and host cells comprising said nucleic acids and the polypeptides coded by the latter.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
