Process for obtaining products with bacterial activity, capable of transforming glycerol into 1,3-propanediol, corresponding strains and application to the industrial production of 1,3-propanediol.

摘要

Process for the production of products having bacterial activity and capable of converting glycerol into 1,3-propanediol. The invention consists in firstly producing bacterial strains or species which ferment glycerol from anaerobic microbial habitats present in nature and enriching by discontinuous fermentation said precultures. The products having bacterial activity are then isolated used to convert glycerol by fermentation into 1,3-propanediol. The invention is characterized in that the conversion results in high yield and in that the biosynthesis of 1,3-propanediol prevents the formation of a large number of by-products.
