Carbon streaming in microalgae: extraction and analysis methods for high value compounds

There is a growing recognition that carbon-neutral biofuels and microalgae are eco-friendly options because of their high CO₂ sequestering capability and ability to grow in wastewater/sea water and non-arable land. Also the intrinsic properties of microalgal systems can be exploited for high value compounds such as carbohydrates, lipids, pigments and proteins. This article provides a comprehensive review of various microalgae cultivation practices utilizing organic and inorganic carbon sources. The merits and demerits of the various extraction and analytical procedures have also been discussed in detail.
