| Patent Application Number | EP1892300 A1 |
| Assignee | Univ Tsinghua, China |
| Relevance | An integrated and cost effective process for the production of biodiesel and conversion of glycerol into 1, 3-propanediol. |
| Type of claims | Publication |
| Overview | This patent discloses a cost effective method of conversion of glycerol into 1,3-propenediol. The method improves the utilization and production efficiency of both raw materials and biodiesel hence greatly reducing the production cost. The method also produces 2,3-butanediol, lactic acid, acetic acid, ethanol or succinic acid as co-products. The process includes, A) inoculating a 1,3-propanediol-producing bacterial strain in a seed culture medium containing crude glycerol, B) adding the seed culture to a fermentation medium containing crude glycerol and C) fermenting, isolating and purifying 1,3-propanediol. |
