Evaluation of the effect of iron nanoparticles on the amount of some products of algae Dunaliella Salina

This research was conducted to evaluate the effect of iron nanoparticles on algae Dunaliella Salina as one of the valuable aquatic species in some saline lakes of Iran, aiming at changing the production of some photosynthetic products (under constant conditions of light, temperature and pH).Samples were taken from Artemia Production Research Center in Kerman province, and transferred under standard conditions to Caspian Research Group of Fisheries & Water Pollutants, and prepared after separation, purification, and cultivation in an modify Johnson medium for further studies. Three treatments were exposed to different doses of iron nanoparticles (0.075, 0.75, and 7.5 mg/l) for 12 days, each with three replications, and compared with control sample using SPSS-V20 software. Significant changes were observed in the amounts of chlorophyll a and b affected by nanoparticles compared to control sample (P≤0.05). Significant changes were also observed in the amounts Beta-carotene and glycerol (all three treatments) (P≤0.05). It seems that different concentrations of nanoparticles can alter the amounts of some of the photosynthetic products of algae Dunaliella Salina and increase some valuable products such as glycerol and beta-carotene.
