Abstract.- The multiple heavy metal resistant ciliates, Oxytricha fallax and Paramecium caudatum, isolated from industrial wastewater have been shown to be potential bioremediator of contaminated wastewater.
We show the results of the experiments on the gravitactic orientation of Paramecium and sea urchin larvae, both of which are known to perform typical negative gravitaxis (Mogami et al., 1988; Ooya et a!., 1992).
Effects of diuron and carbofuran pesticides in their pure and commercial forms on Paramecium caudatum: The use of protozoan in ecotoxicology.
The last group consisted of most samples of the rainy season (March), characterized by the predominance of Askenasia volvox, Aspidisca cicada, Balanium planctonicum, Cyclidium glaucoma, Dileptus sp., Holophrya discolor, Loxodes magnus, Microthorax pusillus, Paramecium aurelia and Vorticella convallaria (Figure 4, Table 2).
Then in 2009, scientists examining DHAB water samples found DNA and ribosomal RNA from protists--single-celled eukaryotes similar to Amoeba and Paramecium. That didn't necessarily mean the protists were living in the DHABs.
In the single-celled organism Paramecium tetraurelia, melatonin treatment increased both the mean and the maximal life span by up to 24% over control animals.
I don't like cauliflower gratin, I never did like it, as far back as I can remember, even when I was in limbo I never ate it, or later on when I was a lictor in Rome, or when I shod horses under Pepin the Short, and when I was a sea-snail or a warbler, or a paramecium: I didn't like it then either--not even when I was a slug in the vegetable garden!
The endosymbiotic bacterium Caedibacter may be found in the cytoplasm of Paramecium, conveying the "killer" trait to these paramecia.

In Kentucky, he explains how single-celled organism the paramecium can orientate itself through touch alone, and that catfish build a picture of their murky river environment through taste buds.
Akira Muto, the study's lead author from the Kawakami lab, used the new tool to map what happens when a zebrafish sees something good to eat, in this case a swimming paramecium. The researchers were also able to correlate brain activity with that prey's capture.
For comparison, researchers analyzed a swimming paramecium and analyzed its tectal activity during perception of a natural object, comparing it to the tectal response of its free-swimming larval fish.
