Yellow 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 کاملSterols of Chlorella. II. The Occurrence of an Unusual Sterol Mixture in Chlorella vulgaris.
The first identification of a sterol in Chlorella was by Klosty and Bergmann (5) in 1952 when they isolated ergosterol from Chlorella pyrenoidosa. More recently, Otsuka (6) identified ergosterol and a A5 sterol in Chlorella ellipsoidea. Ergosterol was the principal component of the mixture. Recent work in this laboratory has been centered about the identification of sterols from other species o...
متن کاملEnhanced Vitamin B12 Production using Chlorella vulgaris
Microalgae Chlorella Vulgaris is enriched in vitamin B12 and cobalt ion which is positioned in the center of the vitamin molecule. This study aimed to investigate how different concentrations of cobalt chloride salt affected the vitamin B12 production by utilizing CO2 gas, to assess C. vulgaris biomass. Therefore, Bold’s basal medium used as the medium and 0.5, 1....
متن کاملMass 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 ...
