Equilibrium experiments of chromium(III) biosorption by microalga (Spirulina sp.) and macroalga (Pithophora varia) were investigated in this paper. Influence of the following process parameters was studied: pH, biomass concentration and temperature. The equilibrium of the process was described with Langmuir equation. The model parameters were determined at various process conditions. The best o...

Background and purpose: Research has shown that aging affects appetite and energy intake. The aim of this study was to investigate the protective effect of aerobic training (AT) and spirulina (SP) on Nesfatin-1 and Peptide YY (PYY) in overweight elderly men. Materials and Methods: In this clinical trial study, 32 overweight elderly men (age 57.50±4.84 years, Body mass index: BMI 26.90±2.85 kg/...

BACKGROUND Altered plasma lipids, oxidative stress, and inflammation have been involved in the pathogenesis of cardiovascular disease. Fish oil has shown inconclusive effects on plasma lipids and oxidative stress. Spirulina has both cholesterol lowering and antioxidant properties. However, the effect of fish oil and spirulina on hypercholesterolemia has not been studied. We investigated the eff...

The effects of sodium bicarbonate concentration, population density, and temperature on the maintenance of an outdoor monoculture of the cyanobacterium Spirulina platensis were studied. A clear response by Spirulina to the concentration of bicarbonate was evident, with 0.2M bicarbonate representing the lowest concentration in which a monoculture could be maintained. When the temperatures fell d...

Phycobiliprotein-containing water and carotenoid-containing methanolic extracts of three different cyanobacteria, Pseudanabaena sp., Spirulina sp. and Lyngbya sp., were studied for their DPPH scavenging, iso-bolographic studies, and anti-nephrolithe activities. The best EC50 values for DPPH scavenging were in Lyngbya water (LW, 18.78 ± 1.57 mg·mg(-1) DPPH) and Lyngbya methanol (LM, 59.56 ± 37.3...

with increasing world populations, production of cost-effective and proper nourishment sources that can rapidly produce large amounts of nutritional value are needed. microalgae are publicly used as nutrient supplement. in this research a screening of endemic potent microalgae was carried out. chlorella , scenedesmus and spirulina sp. were isolated and purified and cultivated in liquid proper m...
