| Resumen: | This document describes a biological test method for the determination of the genotype potential of water components. As test organism the genetic changed bacterium salmonella typhimurium. The bacteria are treated with different concentrations of the test portion and the umu C-gen will be determined as a reaction to the induced gen toxin. As test result the dillution steps of the test portion are given, where a defined gen toxic effect can not be registered. |
