Abstract:: ... Escherichia coli and Enterococci are widely used as indicators of faecal contamination of groundwater while total coliforms, which are of environmental but also of faecal origin, are indicators of the overall quality of the water. The survival of bacteria in groundwater is dependent on many factors including temperature, competition with indigenous bacteria and entrapment in aquifer material. Prev ...

The objectives of this study were to examine differences in attachment between E. coli and enterococci in runoff f ...

Abstract:: ... Fecal indicators such as Escherichia coli and enterococci are used as regulatory tools to monitor water with 24 h cultivation techniques for possible input of sewage or feces and presence of potential enteric pathogens yet their source (human or animal) cannot be determined with routine methods. This critical uncertainty has furthered water pollution science toward new molecular approaches. Member ...

Abstract:: ... Biological reduction of Fe(III) to Fe(II) is a key step in nitrogen oxide (NOₓ) removal by the integrated chemical absorption–biological reduction process. NOₓ removal efficiency strongly depends on the concentration of Fe(II) in the scrubbing liquid. In this study, a newly isolated strain, Enterococcus sp. FR-3, was used to reduce Fe(III) chelated with citrate to Fe(II). Strain FR-3 reduced citra ...

Abstract:: ... Genetic markers from Bacteroides and other faecal bacteria are being tested for inclusion in regulations to quantify aquatic faecal contamination and estimate public health risk. For the method to be used quantitatively across environments, persistence and decay of markers must be understood. We measured concentrations of contaminant molecular markers targeting Enterococcus and Bacteroides spp. in ...
