Soil protists are essential but often overlooked in soils, although they play crucial functional
roles in the terrestrial ecosystem. While soil protists have drawn increased attention to their …

This review analyzes the advantages and disadvantages of using eukaryotic
microorganisms to design whole-cell biosensors (WCBs) for monitoring environmental …

The toxic effects of nanoparticles (NPs) of ZnO and CuO to particle-ingesting model
organism protozoa Tetrahymena thermophila were evaluated. Nano-ZnO was remarkably …

Heat shock proteins (hsps) are induced by a wide range of environmental stressors
including heavy metals in aquatic organisms. However, the effect of heavy metals on …

Microorganisms can mediate antimony (Sb) and arsenic (As) transformation and thus
change their mobility and toxicity. Having similar geochemical behavior, Sb and As are …

Diverse classes of sensors have been developed over the past few decades for on-site
detections of heavy metals. Most of these sensor systems have exploited optical …

Industrial and agricultural processes have led to the prevalence of cadmium in the
ecosystem. A successive build-up of cadmium in food and drinking water can result in …

We studied the cytotoxic effect of the heavy metals Cd, Zn and Cu on three different species
of ciliated protozoa isolated from an urban wastewater treatment plant. The order of toxicity …

Tetrahymena is a single-cell eukaryotic organism present in all aquatic environments and
can easily be maintained in laboratory conditions in a cost-effective manner. This review …

Laboratory toxicity tests, using ciliated protozoa, are scarce and they have been carried out
usually with freshwater species. In this study, we have analysed the acute cytotoxicity of Cd …
