Abstract
This paper emphasizes mainly on the biomass productivity and lipids content of two microalgae strains known by their high lipids content namely: Botryoccoccus sudeticus and Chlorella vulgaris. These strains were first screened for the highest biomass and lipids content, then Plackett-Burman design was used to evaluate the significant media for the growth when using POME waste water as culture medium. Results show that Botryoccocus sudeticus contains high content of biomass and lipids yield. Moreover, all the three factors have positive effect on the biomass productivity, while using one nutrient factor gives much lower biomass These results can be used further as an insight for optimizing the biomass and the oil productivity of the microalgae.
