The aim of the present study was to investigate the effect of nutritional formulations, viz. Bristol's medium (BM), water extract of dairy waste (DW), commercial fertilizers mix (FM), and carbon sources such as NaHCO3, CaCO3, and wheat flour hydrolysate on the biomass productivity and oil content of the algal species Sirogonium sticticum, Temnogyra reflexa, Uronema elongatum, and Chroococcus turgidus. Among the nutritional formulations tested, BM showed the highest average effect, followed by DW, on the biomass and oil contents of the species. As for carbon sources, CaCO3 was more efficient in enhancing algal biomass, while NaHCO3 was proficient in increasing the oil content of the species. S. Sticticum produced the highest average biomass and oil content regardless of the media and carbon sources. It was concluded that in terms of cost effectiveness and commercial availability, DW was a suitable medium for commercial cultivation of microalgae on a large scale.
