Rapid enzyme assay techniques based on direct measurement of β-d-galactosidase
(GALase) or β-d-glucuronidase (GLUase) activity without selective cultivation are used for …

For a better understanding of the short and mid-term impacts of a combined sewer overflow
(CSO) on the microbiological quality of the receiving river, we studied the composition of a …

The Seine river watershed (France) is a deeply anthropogenically impacted area, due to the
high population density, intense industrial activities and intensive agriculture. The water …

The Scheldt watershed is characterized by a high population density, intense industrial
activities and intensive agriculture and breeding. A monthly monitoring (n= 16) of the …

Microbiological water quality is traditionally assessed using culture-based enumeration of
faecal indicator bacteria such as Escherichia coli. Despite their relative ease of use, these …

In many karst regions in developing countries, the populations often suffer from poor
microbial water quality and are frequently exposed to bacterial pathogens. The high …

To facilitate the prompt management of public health risks from water resources, the
fluorescence-based detection of the enzymatic activity of β-d-glucuronidase (GLUC) has …

A sensitive field-portable fluorimeter with incubating capability and triplicate sample
chambers was designed and built. The system was optimised for the on-site analysis of E …

An assay on the indirect amperometric quantification of the β-D-Glucuronidase (GLUase)
activity was developed for the rapid and specific detection of Escherichia coli (E. coli) in …

This study developed a model simulating the seasonal and spatial variations of
microbiological water quality (expressed in terms of Escherichia coli concentrations) in …
