Abstract:
-This study has demonstrated the capability of the two different algae strains namely Chlorella vulgaris and Anabaena variabilis in the consumption of the nutrients from wastewater effluent such as NH4+-N, NO3–N, NO2– N and PO43-and its potential as a biodiesel feedstock. The mixture of prokaryotic algae Anabaena variabilis and eukaryotic Chlorella vulgaris, highest light intensity, a slightly basic medium and 20% CO2 in air were the optimum parameters for biomass production rate. For nutrient removal, the optimum operating conditions were light intensity of 847 lux, pH of 7, pure air and pure culture of Chlorella vulgaris. For biodiesel properties, the predicted cetane number of Anabaena variabilis and the consortium of the Anabaena variabilis and Chlorella vulgaris were determined acceptable values. The predicted iodine numbers for all the algae strains were low.
