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...

Existe uma grande preocupação com um estilo de vida mais saudável por parte crescente dos indivíduos. Nesse contexto, suplementos vitamínicos e alimentos enriquecidos figuram como possibilidades práticas potencializadores nutritivos. A Spirulina Platensis apresenta alta concentração nutrientes é completos naturais disponíveis na natureza. Sendo assim, a produção alimento boa aceitabilidade, gel...

The phycobilin pigments are intensively fluorescence and water soluble. They are categorized into three types: pigments containing high energies (phycoerythrins), intermediate energies (phycocyanins), and low energies (allophycocyanins). Among them, crude-phycocyanin (c-pc) has been considered to be the most preferred one. The present study was undertaken to evaluate the antibacterial activity ...

Spirulina platensis is a high protein content cyanobacterium with known therapeutic properties. Its main protein Phycocyanin is currently as a functional ingredient into various food products to enhance their nutritional qualities acting as food colorant, antioxidant and emulsifier, reducing the use of synthetic additives. The post-harvest treatment of the microalga affects its content of prote...

OBJECTIVE Spirulina has been recognized formerly as a filamentous spiral-shaped blue-green algae but more recently as a genus of photosynthetic bacteria (Arthrospira). This microorganism is considered as a rich source of essential nutrients for human and animals. The present study was conducted to determine potential application of Spirulina for heat-exposed broilers. METHODS Two hundred and ...

The response of Spirulina platensis cells to salinity stress was studied. Once adapted to the higher osmoticum, photosynthetic parameters such as the maximum rate of photosynthesis under saturating irradiance (Px) and the initial slope of the P-I curve (a) are reduced by 15% and 25% in 0.5 M NaCl grown cells, respectively. Salt-adapted cells have a modified biochemical composition; reduced prot...
