Arsenic methylation by an arsenite S-adenosylmethionine methyltransferase from Spirulina platensis.
Arsenic-contaminated water is a serious hazard for human health. Plankton plays a critical role in the fate and toxicity of arsenic in water by accumulation and biotransformation. Spirulina platensis (S. platensis), a typical plankton, is often used as a supplement or feed for pharmacy and aquiculture, and may introduce arsenic into the food chain, resulting in a risk to human health. However, ...
متن کاملInfluence of the hydration degree on copper removal by Spirulina platensis biomass
In the present work, hydrated biomass of Spirulina platensis has been used for copper removal from aqueous solutions. Biomass has firstly been characterised by potentiometric titration and the overall ionic content evaluated. Copper uptake experiments have been carried out using powdered dry biomass of this cyanobacterium, preliminarily hydrated for increasing time, namely 0, 24, 48, 72 and 96h...
متن کاملMineral profile of edible algae Spirulina platensis
Spirulina platensis, is a photosynthetic, filamentous, spiral-shaped, multicellular and bluegreen micro alga. As it contains chlorophyll a, like higher plants, botanists classify it as a micro alga belonging to Cyanophyceae class; but according to bacteriologists it is a bacterium due to its prokaryotic structure. Mexicans (Aztecs) started using this microorganism as human food. Its chemical co...
متن کاملRole 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...
متن کاملConformational Studies on C-Phycocyanin from Spirulina platensis
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...
