“…Microalgae have also been studied in relation to biofuel production since the oil content of their biomass can reach up to 80% of its dry weight (Caporgno et al, 2015;Chisti, 2007). It has been estimated that algal production can be as much as 3200-14600 gallons of lipid per acre per year.…”

“…To improve the cost-effectiveness of the production of biodiesel from microalgae, the use of domestic wastewater (DW) has been proposed as a culture medium in order to integrate several processes: The production of biomass for biofuels, CO2 capture and water treatment (Ji et al, 2013;Razzak et al, 2013). The advantage of this approach is that at the same time that the microalgae remove the excess of nutrients in the wastewater, they produce biomass that can be used for the production of biodiesel (Caporgno et al, 2015). The success of this kind of treatment system is based on the ability of microalgae to effectively assimilate both organic carbon (Octavio et al, 2011) and inorganic nutrients such as N and P, maximising algal biomass and lipid production and achieving efficient nutrient removal (Dominguez et al, 2013).…”

Domestic wastewater (DW) has been used as a substrate for both microalgae biomass production and nutrient removal. Biological treatment with photosynthetic microalgae provides aeration, reducing operating costs and the risk of volatilization of contaminants. It also provides oxygen to the bacteria for degradation of organic compounds. In this study, a microalga was isolated and identified as Scenedesmus sp. An experimental trial was performed using synthetic wastewater with different concentrations of N (40, 90 and 150 mg/L) and P (4, 15 and 50 mg/L). Each assay was inoculated with 1x10 6 cells/ml under 16h of continuous light at 50-µmol m -2 s -1 at and 120 rpm for 7 days. Samples were taken at 0, 3, 5 and 7 days to determine the growth of microalgae and the concentration of nitrates, ammonium and phosphorus. The same treatment was carried out using real DW. Synthetic water of low and medium concentration had higher removal percentages. These were between 50 and 60 for nitrogen and 40 and 70 for phosphorus, with a maximum growth of 1x10 7 cells /ml. For real DW, the removal was 65% for phosphorus and 80% for nitrogen. These results suggest Scenedesmus sp could be used to treat DW, enhancing nutrient removal and obtaining biomass for other purposes.Keywords: Biomass, microalgae, nutrients, wastewater. ResumenLas aguas residuales domésticas se han utilizado como sustrato para la producción de biomasa de microalgas y eliminación de nutrientes. El tratamiento biológico con microalgas fotosintéticas proporciona aireación, reduciendo los costos de operación, el riesgo de volatilización de los contaminantes y proporciona oxígeno a las bacterias para la degradación de compuestos orgánicos. En este estudio se aisló una microalga a partir de aguas naturales y fue identificada como Scenedesmus sp. Se realizó un diseño experimental usando agua residual sintética con diferentes concentraciones de nitrógeno (40, 90 y 150 mg / L), fósforo (4, 15 y 50 mg / L) y la microalga aislada. Cada ensayo se inoculó con 1x10 6 células/ml bajo 16 horas de iluminación a 50-µmol m -2 s -1 por 7 días a 120 rpm. Se tomaron muestras a 0, 3, 5 y 7 días para determinar el crecimiento de microalgas y la concentración de nitratos, amonio y fósforo. El mismo tratamiento se realizó utilizando agua residual domestica real. Las aguas sintéticas de baja y media concentración tuvieron mayores porcentajes de remoción, entre 50-60% para el nitrógeno y 40-70% para el fósforo, con un crecimiento máximo de 1x10 7 células/ml. En el agua residual real, la remoción fue del 65% para el fósforo y el 80% para el nitrógeno. Estos resultados sugieren Scenedesmus sp podría ser utilizada para tratar agua residual doméstica, mejorando la eliminación de nutrientes y obteniendo biomasa para otros fines.

“…Finally, sometimes, also the culture medium plays a role at the biomass growth [63]. For example, Liu et al discovered that C. zofingiensis could grow faster mixotrophically on Bold's Basal medium with acetate than on Tris-Acetate-Phosphate (TAP) medium, because it could also utilize the inorganic carbon salts [38].…”

Utilization of Volatile Fatty Acids from Microalgae for the Production of High Added Value Compounds

Volatile Fatty Acids (VFA) are small organic compounds that have attracted much attention lately, due to their use as a carbon source for microorganisms involved in the production of bioactive compounds, biodegradable materials and energy. Low cost production of VFA from different types of waste streams can occur via dark fermentation, offering a promising approach for the production of biofuels and biochemicals with simultaneous reduction of waste volume. VFA can be subsequently utilized in fermentation processes and efficiently transformed into bioactive compounds that can be used in the food and nutraceutical industry for the development of functional foods with scientifically sustained claims. Microalgae are oleaginous microorganisms that are able to grow in heterotrophic cultures supported by VFA as a carbon source and accumulate high amounts of valuable products, such as omega-3 fatty acids and exopolysaccharides. This article reviews the different types of waste streams in concert with their potential to produce VFA, the possible factors that affect the VFA production process and the utilization of the resulting VFA in microalgae fermentation processes. The biology of VFA utilization, the potential products and the downstream processes are discussed in detail.

With the accelerated increase in World population, human activities leave bigger traces on environment and ecology, which are not always signs for good. Especially places where more concentrated populations live in, like metropolitans or bigger cities, these traces are more significant. Today, World population is more than 7 billions of people, and the individual or industrial activities of this population endanger the nature and many living systems. It is recognized that nature cannot handle this massive amount of negative accumulation and humans started to react to minimize the effects of the circumstances that harm nature. Renewable energy technologies are introduced for a better, green and sustainable energy consumption. With the idea of integrating microalgal biotechnology with renewable energy systems, a novel solution to energy problem has been introduced and a futuristic research area has been developed.
