Abstract Fish as the primary source for essential n − 3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic (DHA) cannot cover global demand these important nutrients resulting in a supply gap of currently 1.1 million tons EPA + DHA annually. A further exploitation natural fish stocks is linked to great damage ecosystems. Oleaginous microalgae are could possibly contribute closing this ...

Understanding potential biochemical interactions and effects among cyanobacteria and other organisms is one of the main keys to a better knowledge of microbial population structuring and dynamics. In this study, the effects of cyanobacteria from benthos and plankton of estuaries on other cyanobacteria and green algae growth were evaluated. To understand how the estuarine cyanobacteria might inf...

In the context of algal biofuels, lipids, or better aliphatic chains of the fatty acids, are perhaps the most important constituents of algal biomass. Accurate quantification of lipids and their respective fuel yield is crucial for comparison of algal strains and growth conditions and for process monitoring. As an alternative to traditional solvent-based lipid extraction procedures, we have dev...

background: this study aimed at determining the appropriate method for dewatering and drying biomass and selecting a suitable organic solvent for lipid extraction. methods: nannochloropsis oculata was cultured in gillard f/2 medium and after reaching the end of the stationary growth phase, algal biomass was separated from aqueous by centrifuge and dried through three methods: oven, air-dried an...
