| Abstract |
Microalgae-mediated integrated approach of reducing effluent load as well as producing high density biomass for varied bio-refineries has been considered a sustainable and carbon efficient strategy worldwide. This study highlights the growth and nutrient removal potential of Thalassiosira weissflogii cultivated in a simulated medium comprising of different proportions of municipal wastewater and artificial seawater enriched with f/2 and metasilicate. The results indicate that the highest cell density was recorded on the fourteenth day in the 50 % setup (63x10(5) cells mL(-1)) followed by the 30 % setup (53.8x10(5) cells mL(-1)). Also, an increase in both protein (83.7 +/- 0.3 mgg(-1)), as well as carbohydrate (16.94 +/- 0.091 mgg(-1)) content, was obtained in the 30 % experimental setup. A considerable removal of nutrients like nitrate nitrogen (26.8 +/- 0.6 %), and total phosphorous (105.5 +/- 1.9 %) was reported in the 50 % wastewater and seawater setups. Although the total lipid % DW was maximum in the control group (35.2 %), the content of monounsaturated fatty acids (MUFA) was substantially high (47 %) in the 50 % culture setup. Thus, this high MUFA-producing, commercially viable, and adaptable strain could serve as a promising source of biodiesel feedstock, promoting a circular sustainable economy. |
