The aim of this study is to determine the relationship between the ciliate populations density
and effluent quality in activated sludge plants. A total of 231 samples taken at three activated …

Biotransformation of chemical contaminants is of importance in various natural and
engineered systems. However, in complex microbial communities and with chemical …

Industrial processes often produce wastewaters that resist biological treatment owing to the
unfamiliarity of some components to biological systems. Availability of nutrients determines …

Recent efforts have been made to culture marine shrimp in systems operating under low or
zero‐water exchange and with decreased water salinity. The aim of this study was to …

Microorganisms present in wastewater treatment plants are responsible for effluent water
quality. In activated sludges, biotic components are represented by decomposers (bacteria …

A remaining challenge within microbial ecology is to understand the determinants of
richness and diversity observed in environmental microbial communities. In a range of …

Three full-scale advanced biological systems for nitrogen removal showing different
efficiencies were assessed during one year, to investigate the protist communities supported …

Protozoa constitute a major link between the highly productive and nutrient retaining
microbial loop and the metazoans of the classical food web. Protozoa are efficient at …

The bioindicator potential of the microeukaryotic community in a full-scale A 2 O wastewater
treatment process was assessed after deactivating the internal recirculation in one of the two …

The assessment of protozoan populations comprises an important tool in evaluating the
efficiency of the activated sludge process for the treatment of wastewater. In this process …
