Biofuels from algae are highly interesting as renewable energy sources to replace, at least partially, fossil fuels, but great research efforts are still needed to optimize growth parameters to develop competitive large-scale cultivation systems. One factor with a seminal influence on productivity is light availability. Light energy fully supports algal growth, but it leads to oxidative stress ...

In this work, microencapsulation of omega-3 lipids from sustainable sources, including oilseeds such as Salvia hispanica L., Echium plantagineum L. and Camelina sativa microalgal (from Nannochloropsis gaditana) enzymatically produced fatty acid ethyl esters (FAEEs), was successfully done by spray drying their outcomes studied. Previous to process, lipid extracts new sources (chia, camelina echi...

Flocculation is one of the principal steps in biodiesel production from microalgae. Eight different flocculants were analysed for their efficiency of flocculation of marine microalga, Nannochloropsis oculata. Maximum flocculation was observed as 93.80 and 87.33% with FeCl3 and Fe2(SO4)3 at a concentration of 0.4 and 0.6g/L respectively at 180min. Zinc salts achieved second maximum efficient flo...

Nannochloropsis is an industrially-promising microalga that may be cultivated for alternative sources of nutrition due to its high productivity, protein content and lipid composition. We studied the growth and biochemical profile of Nannochloropsis 211/78 (CCAP) in optimized flat-plate photobioreactors. Eighteen cultivations were performed at two nutrient concentrations. The fatty acid, protein...

background: this study quantified the effect of four popular culture media in a biodiesel production study on the qualitative and quantitative lipid content, dry biomass, and lipid productivity of nannochloropsis oculata. methods: culture of microalgae was done separately in walne, f/2, sato, and tmrl media. in the logarithmic and stationary growth phases, biomass production and lipid accumulat...
