MicroTester. as a validated method is suitable for rapid microbiological testing of mineral water, carbonated water, tank and running drinking water and other types of water. The time needed for a reliable detection of microorganisms is of key importance: in water industry the real-time (or at least as fast as possible) monitoring of the microbiological properties of the production is indispensable; in public water supply the essential basis of the epidemiological and public health measures is the fast and reliable result of the microbiological inspection. Beside the most important and most widely inspected microbiological contaminants the most relevant disturbing flora was involved to the validation process as well.. 2A. l. (s) + 3H. 2. SO. 4.
