Photosynthetic Electron Transfer in Preparations of the Cyanobacterium Spirulina platensis.
Electron transfer activity in intact trichomes of Spirulina platensis (Nordst.) Geitl. can be observed with either CO(2) or methylviologen as the Hill acceptor. Ferricyanide cannot penetrate the intact trichomes, but photoreduction of this oxidant can be observed when mediated by lipophilic oxidants such as p-phenylenediamine or 2,5-dimethyl-p-benzoquinone. The insensitivity of these reactions ...
متن کاملTwo tuf genes in the cyanobacterium Spirulina platensis.
Probes derived from the tufA gene of Escherichia coli have been utilized to detect homologous sequences on Spirulina platensis DNA. A 6-kilobase-pair fragment of S. platensis DNA appears to contain two sequences homologous to the E. coli gene. Thus, as reported for gram-negative bacteria, the cyanobacterium presumably contains two tuf genes.
متن کاملGrowth and biopigment accumulation of cyanobacterium Spirulina platensis at different light intensities and temperature
In order to find out optimum culture condition for algal growth, the effect of light irradiance and temperature on growth rate, biomass composition and pigment production of Spirulina platensis were studied in axenic batch cultures. Growth kinetics of cultures showed a wide range of temperature tolerance from 20 °C to 40 °C. Maximum growth rate, cell production with maximum accumulation of chlo...
متن کاملApplication of sonication and mixing for nanoencapsulation of the cyanobacterium Spirulina platensis in liposomes
Encapsulation in the food industry is a process in which one or more ingredients or additives (core) are coated with an edible capsule. The use of liposomes is among the many forms of encapsulation of food ingredients. It consists of a sort of microscopic lipid vesicles, where due to the lipophilic and hydrophilic portion of its constituents, substances of various natures can be encapsulated, a...
متن کاملMutagenesis of the cyanobacterium Spirulina platensis by UV and nitrosoguanidine treatment.
The production of Spirulina platensis cells resistant to 8-azaguanine or beta-(2-thienyl)-DL-alanine following mutagenesis with N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) and UV-irradiation is described. The conditions for the mutagenesis were determined by monitoring cell viability and the appearance of the two types of mutants as a function of the stage of growth of the tricomes and the leng...
