Abstract:
The invention relates to the use of nucleic acid sequences for regulating gene transcription and expression, said novel promoters and expression units, methods for modifying or inducing the gene transcription rate and/or expression rate, expression cassettes containing said expression units, genetically modified microorganisms having a modified or induced transcription rate and/or expression rate, and methods for producing biosynthetic products by cultivating said genetically modified microorganisms.
Abstract:
The present invention features methods of increasing the production of a fine chemical, e.g., lysine from a microorganism, e.g., Corynebacterium by way of deregulating an enzyme encoding gene, i.e., fructose- l,6-bisphosphatase. In a preferred embodiment, the invention provides methods of increasing the production of lysine in Corynebacterium glutamicum by way of increasing the expression of fructose-1,6-bisphosphatase activity. The invention also provides a novel process for the production of lysine by way of regulating carbon flux towards oxaloacetate (OAA). In a preferred embodiment, the invention provides methods for the production of lysine by way of utilizing fructose or sucrose as a carbon source.
Abstract:
The invention relates to methods for the zymotic production of fine chemicals, especially L-methionine, containing sulphur using bacteria, wherein a nucleotide sequence coding for a methionine-synthase (methA)-gene is expressed.
Abstract:
The invention concerns novel nucleic acid molecules, the use of said molecules for producing by recombination genetically improved micro-organisms, and a method for preparing fine chemical products, in particular amino acids, using said genetically improved micro-organisms.
Abstract:
The present invention pertains to improved microorganisms and methods for the production of methionine and other sulfur containing fine chemicals using the metl gene from Bacillus subtilis or a gene related to metI. In some embodiments of the present invention, the metI gene or another gene is integrated in a fashion that allows for co-production of a water soluble compound such as methionine or other amino acid and a caortenoid compound.
Abstract:
The invention relates to methods for the production by fermentation of sulphur-containing fine chemicals, in particular L-methionine, using bacteria in which a nucleic acid sequence coding for a methionine synthase gene (metF) is expressed.
Abstract:
The invention relates to novel nucleic acid molecules, the use thereof in the construction of bio-engineering improved microorganisms and methods for the production of fine chemicals, especially amino acids with the aid of said bio-engineered improved microorganisms.
Abstract:
The present invention relates to microorganisms and processes for the efficient preparation of L-amino acids such as L-methionine. In particular, the present invention relates to microorganisms and processes in which the formation and/or accumulation of homolanthionine in the methionine pathway is reduced and/or prevented.
