Comparison of open-air and semi-enclosed cultivation system for massive microalgae production in sub-tropical and temperate latitudes

Effects of pH, Salinity, Biomass Concentration, and Algal Organic Matter on Flocculant Efficiency of Synthetic Versus Natural Polymers for Harvesting Microalgae Biomass

“…After 6 days, when cultures achieved the stationary phase, the microalgae were collected from the photobioreactors for use in the flocculation experiments. In a previous study, Roselet et al [20] cultured N. oculata year-round in an outdoor open system without CO 2 addition and the culture presented a pH naturally ranging from 6 to 8. Therefore, to investigate the influence of pH on flocculant efficiency, three pH values (5, 7, and 9) were tested 30 min after adjustment using 0.5 mol L -1 HCl or 0.5 mol L -1 NaOH solutions.…”

Carotenoid production by the marine microalgae Nannochloropsis oculata in different low-cost culture media

“…It can be grown in wastewater (Uggetti, Sialve, Trably & Steyer, 2014) and in petrol production water (Arriada & Abreu, 2014). Recently, these microalgae have been widely used in several studies on biofuel production at the Microalgae Production Laboratory from the Aquaculture and Marine Biotechnology Center in the Oceanographic Institute of the Federal University of Rio Grande (Arriada & Abreu, 2014;do Valle Borges, de Farias, Odebrecht & de Abreu, 2007; L. Borges, Mor on-Villarreyes, D'Oca & Abreu, 2011;Roselet, Maic a, Martins & Abreu, 2013;Roselet, Vandamme, Roselet, Muylaert & Abreu, 2015;Sales & Abreu, 2014).…”

Recent trends in the mass cultivation of algae in raceway ponds

“…Indoor RWPs have the disadvantage of receiving nearly 20% less transmission of light. However, overall indoor RWPs have been found to have higher productivity due to partial control over salinity and temperature [34].…”

“…For example, it prevents decrease in salinity and dilution of biomass due to rain fall and precipitation and increase in the salinity due to evaporation of water during the summer time. Further, in the winter season, indoor RWPs enjoy relatively higher culture temperature (nearly 4 1C) than the outside environment [34]. Indoor RWPs have the disadvantage of receiving nearly 20% less transmission of light.…”
