BACKGROUND Spirulina platensis, a cynobacterium used frequently as a dietary supplement had been found to exhibit many immune-stimulating and antiviral activities. It had been found to activate macrophages, NK cells, T cells, B cells, and to stimulate the production of Interferon gamma (IFN-γ) and other cytokines. Natural substances isolated from Spirulina platensis had been found to be potent ...

Seaweeds contain high levels of minerals, vitamins, essential amino acids, indigestible carbohydrates, and dietary fiber. The objective of this study was to compare Spirulina seaweed yellow alkaline noodles made with different levels of green seaweed to make Yellow alkaline noodle products of high nutritional quality with rich fiber content. Green seaweed powder (Spirulina) was incorporated in ...

Spirulina, a filamentous cyanobacterium, possesses diverse biological activities and nutritional significance due to high concentration of natural nutrients, having bio-modulatory and immuno-modulatory functions. Different Spirulina preparations influence immune system viz. increase phagocytic activity of macrophages, stimulating the production of antibodies and cytokines, increase accumulation...

Oxidative stress induced by mercuric chloride (5 mg/kg body weight i.p.) in mice substantially increases the lipid peroxidation level along with corresponding decrease in the reduced glutathione and various antioxidant enzymes in liver and increase in serum transaminases activity. Supplementation of Spirulina (800 mg/kg body weight orally, in olive oil, along with mercuric chloride) for 40 days...

The interaction of Zn(II) ions with cyanobacteria Spirulina platensis basic protein C-phycocyanin (C-PC) is studied by fluorescence spectroscopy.Stern–Volmer quenching constant value for Zn(II)–C-PC is determined. The binding energy of Zn(II) ions with C-phycocyanin is determined using equilibrium dialysis and atomic absorption spectroscopy. Cooperative binding of Zn(II) ions with C-phycocyanin...

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...

This study explores the influence of wastewater feedstock composition on hydrothermal liquefaction (HTL) biocrude oil properties and physico-chemical characteristics. Spirulina algae, swine manure, and digested sludge were converted under HTL conditions (300°C, 10-12 MPa, and 30 min reaction time). Biocrude yields ranged from 9.4% (digested sludge) to 32.6% (Spirulina). Although similar higher ...
