Description The microalgae Scenedesmus abundans cultivated in five identical airlift photobioreactors (PBRs) in batch and fed-batch
modes at the outdoor tropical condition. The microalgae strain S. abundans was found to tolerate high temperature (35–45 °C)
and high light intensity (770–1690 μmol m− 2 s− 1). The highest biomass productivities were 152.5–162.5 mg L− 1 day− 1 for
fed-batch strategy. The biomass productivity was drastically reduced due to photoinhibition effect at a culture temperature
of > 45 °C. The lipid compositions showed fatty acids mainly in the form of saturated and monounsaturated fatty acids
(> 80%) in all PBRs with Cetane number more than 51. The fed-batch strategies efficiently produced higher biomass and
lipid productivities at harsh outdoor conditions. Furthermore, the microalgae also accumulated omega-3 fatty acid (C18:3)
up to 14% (w/w) of total fatty acid at given outdoor condition.
