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 کاملSEMICONTINUOUS CULTIVATION OF THE CYANOBACTERIUM Spirulina platensis IN A CLOSED PHOTOBIOREACTOR
The cultivation of photosynthetic microorganisms such as the cyanobacterium Spirulina platensis has been studied by researchers in many countries because these organisms can produce products with industrial potential. We studied the specific growth rate (μx, day) and productivity (Px, in mg/L/day of Spirulina platensis biomass, dry weight basis) of two S. platensis strains (LEB-52 and Paracas) ...
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 کاملEffect of High Salt Stress on Photosynthetic Electron Transport Activities in the Cyanobacterium, Spirulina Platensis
Environmental stresses like temperature, high light, UV radiation and salt stress are known to affect the efficiency of photosynthesis (Stainer and Cohen –Bazire, 1977; Tandeau de Marsac and Houmard, 1993). Salt stress inhibits fundamental processes such as plant growth and productivity which are often associated with the decreased photosynthesis (Greenway and Munns,1980). A number of studies h...
