Process for the Production of D-Amino Acids, Microorganism, and Vector

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent introduces a method for the production of D-amino acids by genetically modifying microorganisms. Specifically, DNA coding for an amino acid racemase enzyme is inserted into a microorganism that already produces L-amino acids, enabling the conversion of L-amino acids to D-amino acids inside the organism. Afterwards, the D- and L-forms are separated for collection.

Use CasesContent extracted from patent full text and abstract with AI.

• Industrial production of D-amino acids for use in pharmaceuticals
• Manufacturing of D-amino acids for food additives or flavor enhancers
• Production of D-amino acids for use as precursors in chemical synthesis

Patent Abstract

The invention relates to a method for the production of D-amino acids, a microorganism, and a vector. According to the invention, DNA encoding an amino acid racemase is introduced into a microorganism producing an L-amino acid, which racemizes an L-amino acid in vivo into a D-amino acid. The D-amino acid is subsequently separated from the L-amino acid.
