Physiological responses of Tetrahymena pyriformis to copper, zinc, cycloheximide and Triton X-100 [PDF]
Protozoa, and particularly ciliates, are essential in aerobic purification processes of wastewaters and have proved to be very sensitive to environmental changes. The physiological response of the ciliate Tetrahymena pyriformis was assessed in terms of

Modeling and insights into the structural basis of chemical acute aquatic toxicity
It has become a top global regulatory priority to prevent and control pollution from the release of synthetic chemicals, which continues to affect the aquatic communities. In the past decades, computational tools were largely used to significantly reduce

Effect of different toxic compounds on ATP content and acid phosphatase activity in axenic cultures of Tetrahymena pyriformis [PDF]
The sensitivity of protozoa, and particularly ciliated protozoa, to environmental changes suggested a study on the physiological responses arising from exposure to toxic compounds.

Continuous Monoxenic Culture of Tetrahymena pyriformis [PDF]
SUMMARY: A two-stage continuous culture apparatus was used to study the growth and feeding kinetics of the ciliated protozoon Tetrahymena pyriformis GL. The food organism, the bacterium Klebsiella aerogenes, was grown in the first stage using sucrose as the limiting nutrient to establish steady-state populations.

A comparative study using a fluorescence-based and a direct-count assay to determine cytotoxicity in Tetrahymena pyriformis [PDF]
A novel cellular cytotoxicity assay using two fluorescent dyes was developed as an alternative method to the standard direct count of viable protozoa under light microscopy.

Ansamitocin-induced Synchrony in Tetrahymena pyriformis [PDF]
Ansamitocins inhibited cell division in Tetrahymena pyriformis W at low concentrations and caused cells to become more rounded. Exposure to ansamitocins for 5 h or more resulted in a burst of synchronous division at 100 min after removal of the antibiotics with a maximum division index of 70%.

Parallel evolution of histophagy in ciliates of the genus
Background Species of Tetrahymena were grouped into three complexes based on morphological and life history traits: the pyriformis complex of microstomatous forms; the patula complex of microstome-macrostome transformers; and the rostrata complex of ...

Biogenic amines at a low level of evolution: Production, functions and regulation in the unicellular Tetrahymena [PDF]
The unicellular eukaryote Tetrahymena synthesize, store and secrete biogenic amines (histamine, serotonin, epinephrine, dopamine, melatonin) and also can take up amines from the milieu.

Cigarette butts as a source of urban ecosystem pollution [PDF]
Cigarette butts are the most common form of litter. About 4.5 trillion cigarette butts are thrown away worldwide each year, polluting various ecosystems. Many chemicals are used in the process of growing tobacco and producing cigarettes.
