It is shown that diabetes can change hematological parameters and some microalgae, i.e. Spirulina platensis, could improve hematological parameters in non-diabetic rats. The purpose of this study was to investigate the effects of Spirulina platensis (SPM) microalgae on hematological parameters in diabetic rats induced by Streptozotocin. Rats, 2.5 males old, were grouped into two sections includ...

The structure of plant-type [2Fe-2S] ferredoxin isolated from Spirulina platensis has been refined using diffraction data to 2.5 A resolution by alternate cycles of simulated annealing and manual revision of the model. The final R factor is 19.9% for 2,912 reflections with F > 2 sigma F between 8.0 and 2.5 A resolution. S. platensis ferredoxin, like other plant-type [2Fe-2S] ferredoxins, has a ...

Biosorption of Cd(II), Ag(I) and Au(III) by cyanobacteria Spirulina platensis, of Au(II)—by Streptomyces spp. 19H, and of Cr(VI) and Cr(III)—by Arthrobacter species was studied by using the dialysis and atomic absorption analysis under various conditions. In particular, the impact of the following parameters on biosorption was studied: pH (for Ag, Cd, Au), living and non-living cells (for Cr), ...

AbstractThe current study aimed to evaluate milk fat and fatty acids profile, nutrients digestibility lactating ewes’ performance as a response supplementing diets with spirulina algae or fish oil in barki ewes. Three experimental were used follow: Control diet based on 60:10:30 concentrate feed mixture (CFM), clover hay, bean straw (T1); control supplemented 10 ml of oil/ kg DM (T2), 5 g Spiru...

The aim of the research is to develop new bakery products with increased functional value by adding ingredients from biomass Spirulina platensis. High quality wheat flour (P1), oatmeal (P2) and whole (P3) sticks were formulated addition 3% S2 preparation based on spirulina, thus increasing bioavailability active components in microalgae. It was established that results an increase total polyphe...

The biosorption of lead(II), cadmium(II) and nickel(II) ions from aqueous solution by Spirulina platensis was studied as a function of time, concentration, temperature, repetitive reactivity, and ionic competition. The kinetic results obeyed well the pseudo second-order model. Freundlich, Dubinin Radushkevich and Temkin isotherm models were applied in describing the equilibrium partition of the...

The use of banana leaf ash extract (BLAE) as a replacement Kosaric medium (KM) to grow spirulina (Spirulina platensis) was investigated. KM partially replaced with more affordable and locally available BLAE at 0, 10, 30, 50, 70% concentrations. grown for 18 days room temperature in the experimental media artificial lighting aeration. By replacing BLAE, 30% produced highest biomass S. 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 ...

A novel photobioreactor was developed with a total volume of 30 m(3) which required merely 100 m(3) of land footprint. The bioreactor was capable of utilizing CO(2) in the flue gas of a power plant as the carbon source for the growth of a freshwater alga, Spirulina platensis, mitigating the greenhouse effect caused by the same amount of CO(2) discharge. Results of the study indicated that the p...

We investigated the effect of Spirulina platensis protean extract and the biliprotein phycocyanin isolated from this microalga, on the activities of the antioxidant enzymes SOD, CAT, GPx, and GR, lipid peroxidation inhibitory activity and glutathione levels after the iron induced oxidative stress in SH-SY5Y neuroblastoma cells. Iron is one of the most important agents that produce oxidative str...
