“…Some studies have been demonstrated that the independence of light to growth is translated to higher biomass yield and consequently downstream processing steps are reduced. Under heterotrophic conditions, it is shown that ω-3 fatty acid concentration can be two or three orders of magnitude greater that those under autotrophic conditions [76].…”

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.

Microalgae are a potential source for various valuable chemicals for commercial applications ranging from nutraceuticals to fuels. This review aims to focus on microalgal as preservative potential to food chain. The main compounds responsible for these properties, like carotenoids, phenolic compounds, antioxidant vitamins, sterols and polyunsaturated fatty acids are discussed because microalgae can be cultivated under controlled conditions to improve their production. We have listed several studies performed in recent years supporting the health benefits that most of these compounds can provide. Therefore, they may represent an excellent source of preservatives in food chain once their safety as a food supplement has been also confirmed.

“…It reported that flocculation by metal salts may be unacceptable if biomass was used in certain aquaculture (or other) applications [16]. Therefore, flocculants based on natural biopolymers were a safer alternative, example for chitosan, which is non-toxic, biodegradable, renewable and ecologically acceptable [17,18]. So it was more suitable for chitosan to flocculate the cells of tropic ocean microalgae Desmodesmus sp.…”
