Abstract:

The aim of this study is to identify microalgal species for higher algal biomass production to achieve sustainable biofuel production and simultaneous nutrients removal from the wastewater used as cultivation medium. T. indica, was cultivated in dairy wastewater in different concentration of DW. The maximum biomass concentration of 0.62 g L-1 was achieved for T. indica. T. indica removed 72.7% nitrate, 63.97% phosphate and 78.96% ammoniacal nitrogen in 100% of DW. The maximum lipid productivity of 18.44 mgL-1d-1 was achieved in DW. T. indica shows the presence of palmitic acid, pentadecylic acid, linoleic acid, eicosanoic acid and oleic acid. This research work showed that T. indica is predominant microalga for higher biomass production for bioenergy generation and removal of nutrients from dairy wastewater.
