Abstract

Microalgae are a natural source of lipids, carotenoids, and other value-added compounds. The combination of nutrients and their precise ratio have a significant impact on the productivity of microalgae-mediated compounds. The biomass, lipid, chlorophyll, and carotenoid production of three microalgae species, namely, Monoraphidium sp., Chlorella sorokiniana, and Scenedesmus obliquus, were investigated by employing standard photoautotrophic media, namely, BG-11, BBM, and HS CHU-10. BBM was found as the most effective medium since it obtained higher biomass, lipids, and carotenoids from microalgae. The lipids and carotenoids were identified using chromatographic and microscopy techniques. The findings showed that although the Monoraphidium sp. biomass productivity was the lowest, it emerged as a substantial producer of astaxanthin, whereas the Chlorella sorokiniana culture could grow in a variety of media and produced β-carotene as a major carotenoid. On the other hand, Scenedesmus obliquus was found to be a considerable source of lipids and β-carotene. This study provided a comprehensive understanding of the appropriate medium selection in order to extract an assortment of value-added compounds from freshwater microalgae species.
