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...

Spirulina has been used for many years as additive since it has high protein content and nutritional value. Cyanobacteria (blue-green algae) are photoautotrophic microorganisms which are widely distributed in nature. Spirulina is the best known genus of Cyanobacteria because of its unique nutritional properties (Caire et al., 2000). It has been proved that consumption of Spirulina is beneficial...

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...

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...

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...
