“…Flocculants disturb the stability of the particles in suspension and allow them to aggregate, causing separation of the solid–liquid phases efficiently, improving the following processes such as centrifugation, sedimentation, and filtration. Usually, flocculants are inorganic multivalent metal salts, organic polymers, and microbes .…”

Summary This paper reviews some of the most important aspects of microalgae as a potential source for biodiesel production. Microalgae are photosynthetic microorganisms that can grow rapidly in a variety of environments because of their unicellular or multicellular structure depending on the species. They have the advantage of self‐reproduction using solar energy and converting it into chemical energy via photosynthesis. This process concludes a full cycle in a few days, obtaining higher lipid yields than terrestrial crops. This review shows several techniques and some methodologies used in the biodiesel production process from microalgae as well as the challenges that must be overcome for large‐scale process and in bio‐refineries.

“…Additionally, adjustment of culture pH to extreme level may require excess amount of chemicals as found in this study; similar amount of chemicals would be necessary to neutralize the supernatant. Hence, biomass harvesting by modulating the culture pH alone could be expensive (Chatsungnoen and Chisti, 2016).…”

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.
