专利号:US-10696992-B2 优先权日:2015-12-18 标 题:Genetically modified bacterial cell factory for thiamine production 发明人:GRONENBERG LUISA; SALOMONSEN BO; FERLA MATTEO; GENEE HANS JASPER 权利人:BIOSYNTIA APS; BIOSYNTHIA APS 摘要:The invention provides a genetically modified bacterium for production of thiamine; where the bacterium is characterized by a transgene encoding a thiamine monophosphate phosphatase (TMP phosphatase having EC 3.1.3.-) as well as transgenes encoding polypeptides that catalyze steps in the thiamine pathway. The genetically modified bacterium is characterized by enhanced synthesis and release of thiamine into the extracellular environment. The invention further provides a method for producing thiamine using the genetically modified bacterium of the invention; as well as the use of the genetically modified bacterium for extracellular thiamine production.
