Health aspects of Spirulina (Arthrospira) microalga food supplement

Nutritional and Toxicological Aspects of Spirulina (arthrospira).

Undernutrition constitutes a public health problem particularly in developing countries. The utilization of algae, particularly Spirulina, as a functional food was suggested decades ago due to the fact that it is not only a protein-dense food source, but because its amino acid profile is considered as of high biologic-value protein content. Spirulina provides essential fats (e.g., gamma-linolen...

Tackling Community Undernutrition at Lake Bogoria, Kenya: the Potential of Spirulina (arthrospira Fusiformis) as a Food Supplement

Photosynthesis, Growth and Cell Composition of Spirulina platensis (Arthrospira) Under Elevated Atmospheric CO2 and Nitrogen Supplement

The consequences of the addition of CO2 (1%) in cultures of S. platensis are examined in terms of biomass yield, cell composition and external medium composition. CO2 enrichment was tested under nitrogen saturating and nitrogen limiting conditions. Increasing CO2 levels did not cause any change in maximum growth rate while it decreased maximum biomass yield. Protein and pigments were decreased ...

Antioxidant activity of the microalga Spirulina maxima.

Spirulina maxima, which is used as a food additive, is a microalga rich in protein and other essential nutrients. Spirulina contains phenolic acids, tocopherols and beta-carotene which are known to exhibit antioxidant properties. The aim of the present study was to evaluate the antioxidant capacity of a Spirulina extract. The antioxidant activity of a methanolic extract of Spirulina was determi...

Role of pH on antioxidants production by Spirulina (Arthrospira) platensis

Algae can tolerate a broad range of growing conditions but extreme conditions may lead to the generation of highly dangerous reactive oxygen species (ROS), which may cause the deterioration of cell metabolism and damage cellular components. The antioxidants produced by algae alleviate the harmful effects of ROS. While the enhancement of antioxidant production in blue green algae under stress ha...
