BACKGROUND Although outdoor cultivation systems have been widely used for mass production of microalgae at a relatively low cost, there are still limited efforts on outdoor cultivation of carbohydrate-rich microalgae that were further used as feedstock for fermentative bioethanol production. In particular, the effects of seasonal changes on cell growth, CO2 fixation, and carbohydrate production...

The reduction of carbon dioxide concentration in the air (CO2) is one most important areas for mitigation climate change that being focused on by various studies. cultivation microalgae a tool can be applied to remove CO2 from atmosphere as they absorb light and produce molecular oxygen during their cultivation. Wastewater treatment, production biofuels, biofertilizers, biomaterials are conside...

Microalgae are a promising feedstock for sustainable biofuel production. At present, however, there are a number of challenges that limit the economic viability of the process. Two of the major challenges are the non-uniform distribution of light in photobioreactors and the inefficiencies associated with traditional biomass processing. To address the latter limitation, a number of studies have ...

The cultivation of microalgae has become a viable option to mitigate increase in CO2 the atmosphere generated by industrial activities since they can capture as carbon source for growth. Besides, produce significant amounts oils, carbohydrates, proteins, and other compounds economic interest. There are several investigations related process, however, there is still no optimal scenario, may depe...

Instead of sole nutrient starvation to boost algal lipid production, we addressed nutrient limitation at two different seasons (autumn and spring) during outdoor cultivation in flat panel photobioreactors. Lipid accumulation, biomass and lipid productivity and changes in fatty acid composition of Nannochloropsis oculata were investigated under nitrogen (N) limitation (nitrate:phosphate N:P 5, N...

A thermophilic cyanobacterium named Thermosynechococcus CL–1 (TCL–1) was cultivated in the flat plate photobioreactors under strong illumination with dense culture to examine the effects of nutrient concentrations on the biomass production, CO2 fixation, and the potential as the feedstock for bioethanol production. The results show that concentrations of Na, NO3, and CaCl2•2H2O, should be decre...
