SEMICONTINUOUS 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 کاملPhotosynthetic 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 کاملEffect of Light Quality on Phycobilisome Components of the Cyanobacterium Spirulina platensis.
Phycobilisomes from the nonchromatic adapting cyanobacterium Spirulina platensis are composed of a central core containing allophycocyanin and rods with phycocyanin and linker polypeptides in a regular array. Room temperature absorption spectra of phycobilisomes from this organism indicated the presence of phycocyanin and allophycocyanin. However, low temperature absorption spectra showed the 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...
