Biosorption of Cd(II), Ag(I) and Au(III) by cyanobacteria Spirulina platensis, of Au(II)—by Streptomyces spp. 19H, and of Cr(VI) and Cr(III)—by Arthrobacter species was studied by using the dialysis and atomic absorption analysis under various conditions. In particular, the impact of the following parameters on biosorption was studied: pH (for Ag, Cd, Au), living and non-living cells (for Cr), ...

Fish that are colored in nature often acquire faded coloration under intensive culture conditions. Experiments adding top-coated algae to the diets of ornamental fish have resulted in color enhancement. Freshwater red velvet swordtails Xiphophorus helleri, rainbowfish Pseudomugil furcatus, and topaz cichlids Cichlasoma myrnae became significantly more intensely colored when fed a diet containin...

Mangueira Lagoon, located in the extreme south of Brazil, has water with physicochemical characteristics such as alkaline pH and carbonate levels propitious for the growth of the cyanobacterium Spirulina platensis. Previously published studies have shown that Mangueira Lagoon water supplemented with small quantities of carbon and nitrogen is suitable for S. platensis cultivation and can signifi...

Introduction: This research aimed at evaluating the hepato-protective effect of the alga Spirulina platensis against diclofenac-induced liver injury in rats. The study’s ultimate aim was to understand whether Spirulina could be developed as a functional food for therapy and protective therapeutic use. Methods: Hepatic injury was induced by administering diclofenac sodium (50mg/kg i.p.) for 5 da...

the aim of this study was to evaluate the ability of microalgae spirulina platensis and chlorella vulgaris to remove nitrate and phosphate in aqueous solutions. spirulina platensis and chlorella vulgar is microalgae was collected in 1000 ml of municipal water and kno3, k2hpo4 was added as sources of nitrate and phosphate in three different concentrations (0.25, 0.35 and 0.45g/l). during the gro...

An investigation of green synthesis titanium dioxide nanoparticles using Spirulina platensis algae extract was undertaken in the Department Sericulture, Forest College and Research Institute, Mettupalayam. The formation, particle size, exterior morphology shape synthesized TiO2 NPs were analyzed through UV-Vis absorbance spectroscopy, X-Ray diffraction Scanning electron microscope (SEM) respect...

  This experiment was carried out in Bandargah Station in Bushehr province. Peneaus semisulcatus larvae were fed on Spirulina platensis as supplementation microalgae. In order to use spirulina platensis in this study, we have to produce biomass and dry production of this microalga. Determination of length and survival rate of Peneaus semisulcatus larvae was carried out as the objective of the s...

The present study deals with exploration of lipid peroxidation induction capacity of flutamide, an anticancer drug, and in vitro evaluation of water extract of Spirulina platensis as a suppressor of flutamide-induced lipid peroxidation. Goat liver homogenate has been used as the lipid source. This evaluation was done by measuring the malondialdehyde and reduced glutathione content of the tissue...

OBJECTIVE Spirulina has been recognized formerly as a filamentous spiral-shaped blue-green algae but more recently as a genus of photosynthetic bacteria (Arthrospira). This microorganism is considered as a rich source of essential nutrients for human and animals. The present study was conducted to determine potential application of Spirulina for heat-exposed broilers. METHODS Two hundred and ...
