Rapid analysis of ß-D-glucuronidase activity in water using fully automated technology
Abstract Microbiological cultivation methods estimate the number of bacteria in water sample mainly as amount of Colony Forming Units in 100 ml (CFU/100ml) or as a Most Probable Number of fecal bacteria in 100 ml (MPN/100ml). The growing amount of molecular methods for specific detection of fecal bacteria allows rapid measurement without the need for cultivation. These methods could determine ...
