The biosorption of Cu(2+) by free and poly acrylamide gel (PAG) immobilized Spirulina platensis (SpiSORB) was characterized under batch and continuous packed bed columnar reaction systems. The biosorption of Cu(2+) was shown to be highest at pH of 6.0 for both types of biomass. The PAG immobilization process did not interfere with the Cu(2+) binding sites present on biomass leading to cent perc...

We have probed the absorption changes due to an externally applied electric field (Stark effect) of Photosystem I (PSI) core complexes from the cyanobacteria Synechocystis sp. PCC 6803, Synechococcus elongatus and Spirulina platensis. The results reveal that the so-called C719 chlorophylls in S. elongatus and S. platensis are characterized by very large polarizability differences between the gr...

       This study was designed to explore the protective effects of ascorbic acid and water extract of Spirulina platensis (blue green algae) on methotrexate-induced lipid peroxidation using goat liver as the lipid source. This in vitro evaluation was done by measuring the malondialdehyde, 4-hydroxy-2-nonenal, reduced glutathione and nitric oxide content of tissue homogenates....

Cyanobacteria generate biomass under photoautotrophic conditions during photosynthesis. Cultivation of cyanobacteria photoheterotrophic using various organic carbon sources can increase yield biomass. In the current study, effect on growth properties and morphology Spirulina platensis, as well production photosynthetic pigments: chlorophyll a, carotenoids, phycocyanin were investigated. Carbon ...

The cyanobacterium Arthrospira is among the most well-known food supplements worldwide known as "Spirulina." While it is a widely recognized health-promoting natural product, there are no reports on the molecular diversity of commercially available brands of "Spirulina" supplements and the occurrence of other cyanobacterial and heterotrophic bacterial microorganisms in these products. In this s...

Spirulina platensis trichomes grown in Zarrouks medium having total Na+ concentration as 0.14 M when transferred to fresh Zarrouks medium containing enhanced level of Na+ ions equal to 0.86 M showed 30% more accumulation of Na+ intracellularly as compared to the control. An inhibition of photosystem II activity to almost 66% was observed. Also due to this exposure to high Na+, the room temperat...
