Selenium is a trace element performing important biological functions in many organisms including humans. It usually affects organisms in a strictly dosage-dependent manner being essential at low and toxic at higher concentrations. The impact of selenium on mammalian and land plant cells has been quite extensively studied. Information about algal cells is(More)
A flue gas originating from a municipal waste incinerator was used as a source of CO2 for the cultivation of the microalga Chlorella vulgaris, in order to decrease the biomass production costs and to bioremediate CO2 simultaneously. The utilization of the flue gas containing 10–13% (v/v) CO2 and 8–10% (v/v) O2 for the photobioreactor agitation and CO2(More)
In the cultures of the alga Chlamydomonas reinhardtii, division rhythms of any length from 12 to 75 h were found at a range of different growth rates that were set by the intensity of light as the sole source of energy. The responses to light intensity differed in terms of altered duration of the phase from the beginning of the cell cycle to the commitment(More)
Cyclin-dependent kinases (CDK) play a key role in coordinating cell division in all eukaryotes. We investigated the capability of cyclin-dependent kinases CDKA and CDKB from the green alga Chlamydomonas reinhardtii to complement a Saccharomyces cerevisiae cdc28 temperature-sensitive mutant. The full-length coding regions of algal CDKA and CDKB cDNA were(More)
