“…Moreover, biodiesel produced from heterotrophically cultured algae oils had similar properties to diesel fuel in terms of density, viscosity, heating value, and H/C ratio (Xu, Miao et al 2006). In addition to lipid production, high value byproducts can be obtained from heterotrophically cultured microalgae, including polyunsaturated fatty acids and carotenoids (Chen and Chen 2006).…”

“…The pH of the culture broth seems to be an important factor. Although the appropriate pH of each microalga species differs, it has been repeatedly found that controlling the pH of the process results in higher biomass and product yields than when allowing it to vary naturally [38,50,61]. Under these conditions it is more difficult for pH-related inhibition, caused by the uptake of VFA to be developed, such as cytosolic pH acidification [62].…”

“…More specifically, ammonium seems to be the preferred nitrogen source by most species, since it needs the less energy for its breakdown and uptake [3]. After ammonium, organic substrates like urea and glycine are usually more suitable nitrogen sources than inorganic ones [51,61].…”

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.

“…Liang et al (2009) noted that the growth of C. vulgaris under autotrophic conditions yielded 722 mg L -1 of algal biomass in 6 days of culture. Carbon, nitrogen and phosphorous sources are three main influencing important nutrients microalgae growth (Chen and Chen, 2006), and use of glycerol as a carbon source strongly stimulate its growth. About 45 % of microalgae organism is composed of carbon (Singh et al, 2011).…”

RESUMO -Microalgae are potential sources of high value chemicals and bioactive compounds. To promote the cell productivity, culture conditions such as carbon and nitrogen sources, irradiance, temperature, bioreactor design have been investigated. Under mixotrophic conditions, some microalgae grows rapidly and to have a higher growth rate when compared to photoautotrophic conditions. This works reports Chlorella vulgaris production under mixotrophic conditions using glycerol and corn steep licor. The factorial design (2 2 plus star central) was performed with 0.5-1.5% gycerol (C gly ) and 0.5-1.5% corn steep liquor (C csl ) using maximum cell concentration (X m ), cell productivity (P X ) as response. Results from the response surface methodology were that the X m of 1.52 g L -1 was obtained using 0.9 % of G and 1.2 % of CSL. The highest P X value was 232 mg L -1 day -1 with 1.5% of G and CSL. Therefore, these models can be useful to predict maximum cell concentration in mixotrophic cultures.
