Mass adaptation to selenomethionine in populations of Chlorella vulgaris.
Permanent transformations in populations of microorganisms are most frequently brought about by environmental selection of randomly occurring mutants. Changes that can be environmentally induced in all or most cells of a population and retained in environments that are non-inducing have also been reported. One instance is the alteration in serotype of protozoa such as paramecium, occasioned by ...

متن کاملYellow Mutant of Chlorella vulgaris
An antiserum to tobacco glycolate oxidase has been prepared by injection of the purified enzyme into rabbits. Double gel diffusion tests between the antiserum and purified antigen and also with a crude tobacco preparation gave a single immunoprecipitation band. Crude extracts of Euglena gracilis Z Klebs, containing glycolate dehydrogenase, and of Chlorella vulgaris 211-llh/20, containing glycol...
متن کاملMetabolism of urea by Chlorella vulgaris.
Urea metabolism was studied with nitrogen-starved cells of Chlorella vulgaris Beijerinck var. viridis (Chodat), a green alga which apparently lacks urease. Incorporation of radioactivity from urea-(14)C into the alcohol-soluble fraction was virtually eliminated in cell suspensions flushed with 10% CO(2) in air. This same result was obtained when expected acceptors of urea carbon were replenishe...
متن کاملQSAR study of aromatic compounds toxicity to Chlorella vulgaris
As demands for energy have increased worldwide, oil has become the main pollutant of the ocean. The impact of aromatic compounds, which are primary pollutants in oil, on various marine ecosystems has become a growing concern. Establishing a quantitative structure–activity relationship (QSAR) model to predict the toxicity of unknown aromatic compounds may thus serve as an important pollution-pre...
