Mitochondrial chromatin in Paramecium aurelia
Molecular and General Genetics MGG, 1980Chromatin-like structures have been observed in material extracted from the mitochondria of Paramecium aurelia and evidence is presented which establishes that these structures do not originate from nuclear contamination of mitochondrial preparations but are exclusively of mitochondrial origin.

The classes of endosymbiont of Paramecium Aurelia
Journal of Cell Science, 1969ABSTRACT The endosymbionts of Paramecium aurelia appear to consist of a number of different Gram-negative bacteria which have come to live within many strains of paramecia. It is not known whether in nature this relationship is mutually beneficial or not.

The temporal occurrence of some Paramecium aurelia species is still an intriguing problem as cysts were never reported to exist in the Paramecium genus. A sequence of species occurrence was studied (by strain crosses and molecular identification) in five

The occurrence of ciliates, especially the Paramecium aurelia complex, has not yet been studied in many parts of the world, or sampling was done only occasionally. Generally, the southern hemisphere still awaits investigation.

The metabolism of stigmasterol and cholesterol by Paramecium aurelia
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1971Abstract 1. 1. Paramecium aurelia , stock 299, can be grown in axenic culture only when supplemented with fatty acids and an appropriate sterol. The metabolic fate of nutritionally active stigmasterol and inactive cholesterol was determined. 2. 2. Stigmasterol is converted to 7-dehydrostigmasterol.

New stands of species of the Paramecium aurelia complex in Africa and Europe.
Folia biologica, 2014The relevance of geographical distribution and the roles of dispersal and spatial isolation during the speciation of microorganisms are nowadays of great interest.

New Stands of Species of the Paramecium aurelia Complex in Yakutia, Russia.
Folia biologica, 2015Paramecium is one of the most studied genera among ciliates. In particular, it is a model organism for investigation of the sibling species problem (also known as the cryptic species problem), spatial distribution, and its role in speciation.
