The aim of the present study was to investigate the prokaryotic community structure of the anaerobic ciliate, Metopus sp. using rRNA sequencing, fluorescence in situ hybridization (FISH), and transmission electron microscopy (TEM). Metopus sp. was physically separated from anaerobic granular sludge in a domestic wastewater treatment plant and anoxically cultivated for 7 d. 16S rRNA gene sequenc...

We investigated the colonization process and community dynamics of periphytic ciliates in a floodplain lake. To elucidate functional role ciliates, we variations their traits during colonization. Our research revealed that ciliate differs significantly between spring summer, mainly due to differences water temperature hydrological regime. The most pronounced influence temperature-initiated was ...

Ciliates are well known for their unusual tricks of nuclear remodeling. A roulette-like method for mating type choice in Tetrahymena adds an interesting new twist to their repertoire.

How do cells and nature \compute"? They read and \rewrite" DNA all the time, by processes that modify sequences at the DNA or RNA level. In 1994, Adleman's elegant solution to a seven-city Directed Hamiltonian Path problem using DNA 1] launched the new eld of DNA computing, which in a few years has grown to international scope. However, unknown to this eld, ciliated protozoans of genus Oxytrich...

Translation is carried out by the ribosome and several associated protein factors through three consecutive steps: initiation, elongation, and termination. Termination remains the least understood of them, partly because of the nonuniversality of the factors involved. To get some insights on the evolution of eukaryotic translation termination, we have compared the phylogeny of the release facto...

In the quest of finding local strains marine ciliates that can be easily cultured under a broad range salinity and fed with microalgae, Fabrea salina Henneguy, 1890 Condylostoma sp. Bory de St. Vincent, 1826 were for 22 days in small volumes at temperature 16–18 °C flagellated microalgae. F. presented clear preference 40 ppt Condylostoma. 20 ppt. Rhodomonas Hill Wetherbee, 1989 most efficient f...

Predicting the performance of aquatic organisms in a future warmer climate depends critically on understanding how current temperature regimes affect organisms' growth rates. Using meta-analysis for published experimental data, we calculated activation energy (Ea) to parameterize thermal sensitivity marine and freshwater ciliates, major players food webs. We hypothesized that their rates increa...
