Abstract (en)

[origin: WO03004697A2] The invention relates to a method and means for the rapid identification of mutations. The test strains used in the invention contain a reporter system and a selection marker. An antibiotic resistance protein, which after mutation allows the selective growth of the revertant and the targeted induction of the inducible reporter system of the developing revertants acts as the selection marker. Proteins that are capable of directly or indirectly triggering a measuring signal are used as the reporters. The mutations are identified by means of the reporter signal of the developing revertants, in such a way that the evaluation can take place after only a few hours.
