摘要： The present invention relates to a improved process for the biotechnological production of compounds for which ribose-5-phosphate, ribulose-5-phosphate or xylulose-5-phosphate is biosynthetic precursor like riboflavin (vitamin B2), FAD, FMN, pyridoxal phosphate (vitamin B6), guanosine, GMP, adenosine, AMP. The invention further pertains to the generation of the organism producing those compounds. It furthermore relates to the generation of mutated transketolases that allow normal growth on glucose but reduced growth on gluconate when introduced into the production strains and to polynucleotides encoding them.

摘要： The present invention provides a process for producing a target fermentation product. This process includes providing a fermentation medium containing a recombinantly-produced microorganism that over-produces a fermentation product and contains a mutation which causes auxotrophic growth of the microorganism wherein the auxotrophy within the microorganism does not compromise the ability of the microorganism to produce the fermentation product. The medium is then supplied in excess with all substrates required for production of the fermentation product and in growth limiting amounts with a substrate complementing the auxotrophy. Host cells, vectors, and polynucleotide sequences used in the process are also provided. The polynucleotide sequences of the present invention include sequences derived from the biotin operon of B. subtilis and in particular the bioFDB gene cassette.
