Biomass production of Dunaliella salaina using Dewarln's media supplemented with different initial concentration Iron, Selenium and Nickel

摘要

Biomass production of marine and fresh water microalgae is most important now days for various applications. All over the world various strategies are using to increase microalgal biomass yields. In this study we used trace elements such as Fe, Se andNi as supplements to Dewarln's media to enhance the biomass production of Dunaliella salaina and optimized its concentrations. The maximum biomass yield was obtained Fe, Se and Ni amended cultures for 60 mu g/L, 40 mu g/L and 40 mu g/L respectively. Statistical analysis indicated that the Fe, Se and Ni concentrations and biomass yield are interdependable, because they showed positive correlation for optimum concentration. These trace elements can be used as an additional nutrient supplement for biomassproduction of D.salina at the large scale.
