Abstract
The present invention provides a method for the anaerobic production of 1,3 propanediol, by culturing a Clostridium strain in an appropriate culture medium comprising glycerol as a source of carbon, wherein said Clostridium strain does not produce substantially other products of the glycerol metabolism selected among the group consisting of: butyrate, lactate, butanol and ethanol, and recovering of 1,3-propanediol.

- culturing a Clostridium strain in an appropriate culture medium comprising glycerol as a source of carbon, wherein said Clostridium strain does not produce substantially other products of the glycerol metabolism selected of from:
- butyrate, lactate, butanol and ethanol, and
- recovering 1,3-propanediol.
(canceled)
A 1,3-propanediol-producing Clostridium strain, wherein the strain does not produce substantially other products of the glycerol metabolism chosen from butyrate, lactate, butanol, and ethanol.
