Bile Pigments, Protein Interaction, Conformation, Denaturation The chromophore-protein interactions of C-phycocyanin (C-PC) from Spirulina platensis have been studied by following the partial and complete denaturation with UV-Vis spectroscopy. From comparison with published MO calculations, an elongated conformation of the chromophore is sug­ gested for native C-PC, a cyclic one for denatured C...

       This study was designed to explore the protective effects of ascorbic acid and water extract of Spirulina platensis (blue green algae) on methotrexate-induced lipid peroxidation using goat liver as the lipid source. This in vitro evaluation was done by measuring the malondialdehyde, 4-hydroxy-2-nonenal, reduced glutathione and nitric oxide content of tissue homogenates....

A laboratory experiment was conducted to assess the bioaccumulation of microelements Fe 2+, Cu 2+, Zn 2+ and their effects on the growth and pigment contents of Spirulina platensis in Zarrouk’s media. The mentioned metals concentrations enhanced separately to tenfold of the Zarrouk’s content. The results indicated no differences in the dry weights for the different medias (p>0.05). A rapid incr...

spirulina platensis, a cyanobacterium of economic important was studied for the tolerance to cadmium. the bioassay studies showed the ec50 value to be 1.53 mg/g. the cyanobacterium was very sensitive to low metal concentration and the productivity was also reduced. the chlorophyll pigments reduced with decreasing the algal biomass. the algal survival rate showed a marked reduction in their surv...

The use of a mechanical pre-treatment such as high-shear homogenization (HSH - 20,000 rpm, 96 kJ/kgSUSP) in combination with pulsed electric fields (PEF 20 kV/cm, 100 was proposed to selectively and efficiently recover water-soluble proteins, carbohydrates, C-phycocyanin from A. platensis suspensions during water extraction (25 °C, 3 h). Efficiencies combined treatment + PEF) were compared thos...

Spirulina platensis is a micro alga which contains many essential fatty acids, like gamma linolenic acid, stearic acid, myristic acid, linoleic acid, heptadecanoic acid etc. The composition of individual fatty acids had been found out through GC-MS analysis based on their retention time and molecular weight. Winterization procedure was used for the extraction of fatty acid mixture. Fatty acid m...

This study explained Enhancing Fattening Lamb Performance with Spirulina platensis: Insights into Growth, Blood Metabolism, and Antioxidant Status. 20 lambs. (7-8 months old, (45.0±0.5 kg) were randomly divided two groups, one group receiving a commercial diet the second same but 1g/10kg B.W/day of platensis powder. The lambs weighed at various points during 42-day experiment results showed tha...

The influence of culture temperature and the concentration of sodium nitrate (NaNO3) on the gas-chromatographic profile of the fatty acids of the filamentous cyanobacterium Spirulina platensis was evaluated. We found that temperature was the most important factor and that the greatest amount of gamma-linolenic acid (GLA) was obtained at 30 degrees C, the fatty acid profile of the Spirulina cult...
