Email this article Bioremediation Of Dairy Wastewater Using Microalgae For The Production Of Biodiesel
Abstract
This study describes the feasibility for treatment of dairy waste waters in batch cultures by using selected strains of green microalgae namely Chlorella vulgaris, Botryococcus braunii and a mixed algal culture in indoor and outdoor. The Biomass productivity peaked on the 6th day. Best results were observed in C. vulgaris strain in both indoor and outdoor studies with biomass productivity of 0.51g/L, chlorophyll concentration of 0.039mg/L and lipid yield of 0.030g/L in indoor cultures whereas 0.59g/L of biomass productivity, 0.045mg/L chlorophyll concentration and 0.035g/L lipid yields were obtained in outdoor studies.. Gas Chromatography mass Spectrophotometer (GC MS) analysis of the extracted lipids showed that major components in C.vulgaris and mixed algae were palmitic acid, staeric acid and oleic acid where as oleic acid was the major component in B.braunii and palmitic acid, staeric acid were also present in minor amounts.
