摘要:
The invention relates to a process for the preparation of L-amino acids. The process involves fermenting an L-amino acid producing coryneform bacteria in a culture medium, concentrating L-amino acid in the culture medium or in the cells of the bacteria, and isolating the L-amino acid produced. The bacteria has an amplified gene encoding the Zwischenferment protein.
摘要:
The present invention relates to polynucleotides that encode proteins having OpcA enzymatic activity. These polynucleotides can be used for increasing lysine biosynthesis in Coryneform glutamicum.

摘要:
A device for supporting two constructional elements against each other consisting of at least one upset tube arranged between pressure transmitting plates located at the ends of the tube for the purpose of limiting inward and outward bulging. The upset tube is coaxially arranged between two supporting tubes having a smaller length than the upset tube of which the external supporting tube encloses the upset tube at a radial distance.
