Application of a Tetrahymena pyriformis bioassay system for the rapid detection of toxic substances in wastewaters
A bioassay technique based upon the respiratory response of Tetrahymena pyriformis to intoxication, which gives results within 10 min, was used to evaluate the quality of a number of effluents from three wastewater treatment plants in the PretoriaJohannesburg area. Toxic activity was detected in both treated and untreated wastewater effluent. The technique was shown to be sufficiently sensitive...
متن کاملA NEW BIOLOGICAL SCREENING SYSTEM FOR LOCAL ANAESTHETICS BY INHIBITION MOBILITY OF TETRAHYMENA PYRIFORMIS
An alternative in vitro approach to drug screening has been the use of human cell cultures for antiviral agents and microbial cell cultures for the assessment of the carcinogenic potential of selected compounds. A number of protozoan species have been also used as drug screens for anti-protozoal agents. The ciliated protozoan Tetrahymena pyriformis species has been widely utilised as a dru...
متن کاملExocytotic and phagocytotic activities of Tetrahymena pyriformis are not influenced by Clostridium botulinum neurotoxins
The ciliate Tetrahymena pyriformis GL was tested for its applicability to the detection of botulinum neurotoxins. Botulinum neurotoxins attack different proteins of the SNARE-complex, which is involved in fusion processes of the cellular membrane traffic. The exocytosis of enzymes and the phagocytosis of germs include several presumptive SNARE-dependent pathways within T. pyriformis. Acid phosp...
متن کاملStructure of Macronuclear Envelopes of Tetrahymena Pyriformis in the Stationary Phase of Growth
In a preceding publication a method was reported by which fragments of the nuclear envelopes of Tetrahymena pyriformis could be isolated (10). When macronuclear envelopes were isolated from exponentially growing cultures of the amicronucleate Tetrahymena pyriformis strain GL, two types of envelope pieces were observed which differed markedly in the structure of their pore complexes. Type A cont...
متن کاملIsolation of ceramide-monomethylaminoethylphosphonate from the lipids of Tetrahymena pyriformis W.
Ceramide-monomethylaminoethylphosphonate has been isolated for the first time from the lipids of Tetrahymena pyriformis W and characterized on the basis of its chromatographic mobility, chemical analysis, and infrared and nuclear magnetic resonance properties.
