Preliminary evaluation of biomass and lipid production potential of Nannochloropsis sp. under optimal conditions with different wastewater samples for Exopolymeric substances (EPS) production [PDF]
Wastewater is a source of toxic chemicals, heavy metals and various pathogenic microorganisms. Disposal of untreated wastes into the environment causes antibiotic resistance of organisms and various pollutions. An efficient method for treating wastewater,
