摘要:
The present invention generally relates to the microbiological industry, and specifically to the production of L-serine or L-serine derivatives using genetically modified bacteria. The present invention provides genetically modified microorganisms, such as bacteria, wherein the expression of genes encoding for enzymes involved in the degradation of L-serine is attenuated, such as by inactivation, which makes them particularly suitable for the production of L-serine at higher yield. The present invention also provides means by which the microorganism, and more particularly a bacterium, can be made tolerant towards higher concentrations of serine. The present invention also provides methods for the production of L-serine or L-serine derivative using such genetically modified microorganisms.
摘要(中):
本发明一般涉及微生物工业,特别涉及使用转基因细菌生产L-丝氨酸或L-丝氨酸衍生物。 本发明提供了遗传修饰的微生物,例如细菌,其中编码参与L-丝氨酸降解的酶的基因的表达被减弱,例如通过失活,这使得它们特别适用于在较高的L-丝氨酸生产中 产量。 本发明还提供了使微生物,特别是细菌可以制备成更高浓度丝氨酸的耐受性的方法。 本发明还提供使用这种转基因微生物生产L-丝氨酸或L-丝氨酸衍生物的方法。
