Abstract: Human activities introduce heavy metals to the hydrosphere in many ways such as burning of fossil fuels, smelting of ores, municipal sewage, industrial effluent, mining activities, landfill, mineral weathering, underground toxic waste disposal, etc.. These contaminants, regardless of their sources, are easily dispersed into the aquatic system, and tend to accumulate in living organisms, resulting in various disorders and diseases in the ecosystem. Over the last decades, biosorption has gained importance in the field of water and wastewater treatment. Many studies have demonstrated that biosorption, a part of being a low cost technique, is simple, environmentally friendly and shows a good performance for the separation and removal of organic and inorganic pollutants. Since, it is unusual to find stream of wastewater contaminated by only a sole pollutant, the intensity of interaction which depends on concentration of each component of a multi-component system should be considered.

Abstract: In this study, it is aimed to obtain value-added biobased products such as free fatty acids, phenolic compounds extracted from a microalga species, Nitzschia sp.. The lipid content of the microalga was determined after the Soxhlet extraction applied to freeze-dried biomass. The lipophilic phase soluble in hexane obtained as a result of extraction was distilled and fatty acids were derivatized to fatty acid methylesters (FAME) before the GC/FID analysis, where the fatty acid composition was identified. This oil phase gave response to 20 of 37 components present in the FAME mix standard. The major components found in Nitzschia sp. were palmitic acid (C16:0), palmitoleic acid (C16:1), myristic acid (C14:0), and eicosapentaenoic acid (EPA) (C20:5ω-3), respectively. Ethanol extraction was applied to the remaining phase and this solid extract was evaluated in terms of polyphenolic content, antioxidant capacity and bioactivity. Phenolic compounds such as flavonoids, phenolic acids and tannins
