Microalgae are the quickly growing thalloid organisms and can be used as a renewable source of green energy. The present study focused on the uni-algal culturing, biomass productivity, viability testing of synthetic seed, oil extraction and chemical profiling of the micro-alga, Scenedesmus obliquus. Alga was isolated from leaves and cultured in the Bolds Basal Medium (BBM). The uni-algal culture of the species was developed by serial dilution method. The present study confirmed that BBM was the most successful culture medium for cultivating Scenedesmus obliquus. In the preliminary study, it was found that the biomass productivity of alga was higher in the log stage and later it was decreasing. Synthetic seed test proved that algal beads had more storage viability than pure culture and extend up to years. The percentage of oil in S. obliquus was 54.2 ± 0.0.49%. The GC–MS analysis established that algal oil consists of altogether 37 chemical components with a variety of properties.
