“…Microalgae are suitable candidates for biooil due to their high lipid contents, and their lipid production is highly influenced by the growth conditions of the algae, which in turn, creates an opportunity to enhance production. For instance, a conspicuous increment of lipid production by C. sorokiniana under exogenous ethanol-stress [ 64 ] and increased biooil content by C. vulgaris under nitrogen-depleted media [ 65 ] have been reported. Moreover, microalgae can be integrated with other systems to enhance the output.…”
