Method for Determining L-Serine, Gene Sequene, Vectors and Micro-Organisms

摘要

The folic acid concentration in amino acid producing organisms is reduced or completely removed in order to increase the production of L-serine. The enzymes and genes, which are involved in the biosynthesis of folic acid, can be completely excluded or at least reduced in activity. In a preferred embodiment, SEQ ID NOs: 1-7 are utilized.
