Blue green algae also called cyanobacteria are considered to be the photosynthetic prokaryotes. Their similarities with both higher plants and simple bacteria have made them ideal model systems for intensive research in varied spheres of biology. Their role in nitrogen fixation is well known but their role as prebiotics to support the growth of probiotic bacteria is an upcoming field of study. ...

environment contamination by heavy metals is a major issue threatening human health. adsorption is one of the biological processes for removing toxic metals from wastewater. the aim of this study was to determine the rate of lead biosorption from industrial wastewater by spirulina platensis. this laboratory scale experimental study was performed during april 2014 to october 2014 in environmenta...

A new direction in the development of pharmaceutical and cosmetic products, provides for widespread use pigment containing components extracts microalgae blue-green algae. However, these requires a deeper study their effect on humans, including microbiota. In our experiments, it was found that extract algae Arthrospira platensis (commercial name drug Spirulina), with phycocyanin content 38%, is...

Probes derived from the tufA gene of Escherichia coli have been utilized to detect homologous sequences on Spirulina platensis DNA. A 6-kilobase-pair fragment of S. platensis DNA appears to contain two sequences homologous to the E. coli gene. Thus, as reported for gram-negative bacteria, the cyanobacterium presumably contains two tuf genes.

Exposure of algae or plants to irradiance from above the light saturation point of photosynthesis is known as high light stress. This high light stress induces various responses including photoinhibition of the photosynthetic apparatus. The degree of photoinhibition could be clearly determined by measuring the parameters such as absorption and fluorescence of chromoproteins. In cyanobacteria an...

Algae are widely used as biosorbent for the sorption of heavy metals, however sorption of oil on algae has not been explored. Algae in marine and fresh water environment may affect the fate and transport of spilled oil. Sorption of diesel and lubricating oil was studied using dead biomass of Spirulina sp. and Scenedesmus abundans. The rate and extent of sorption was studied in well mixed batch ...

Spinal cord injury (SCI) is a devastating disease that leads to permanent disability and causes great suffering. The resulting neurological dysfunction and paralysis is proportional to the severity of the trauma itself. Spirulina is widely used as a nutritional supplement due to its high protein and antioxidant content. In the present study, the protective effect of the Spirulina treatment on l...

Background: Isolation of methyl gamma linolenate from Spirulina platensis using flash chromatography and its apoptosis inducing effect against human lung carcinoma A549 cell lines. Methods: Gamma linolenic acid is an important omega-6 polyunsaturated fatty acid (PUFA) of medicinal interest was isolated from microalgae Spirulina platensis using flash chromatography system (Isolera system) as its...
