The present invention is relative to a method for producing 1,2-propanediol by fermentation, comprising : cultivat-ing a microorganism producing 1,2-propanediol in an appropriate medium comprising a source of sucrose, and recovering the 1,2- propanediol being produced, wherein the microorganism is able to utilize sucrose as sole carbon source for the production of 1,2- propanediol. In a preferred aspect of the invention, the source of sucrose is obtained from plant biomass, and is in particular sugar cane juice.

La présente invention concerne un procédé pour produire du 1,2-propanediol par fermentation, comprenant : la culture dun micro-organisme produisant du 1,2-propanediol dans un milieu approprié comprenant une source de saccharose, et la récupération du 1,2-propanediol produit, où le micro-organisme est capable dutiliser du saccharose en tant que seule source de carbone pour la production de 1,2-propanediol. Dans un aspect préféré de linvention, la source de saccharose est obtenue à partir de biomasse de plante, et est en particulier du jus de canne à sucre.
