- Аннотация: Integrating cultivation with wastewater treatment improves the economics of microalgal based biofuel production and allows for the sustainable reuse of nitrogen (N) and phosphorus (P) from waste streams. Batchcultivation of a locally isolated green microalga, UHCC00027, and an indigenous algal-bacterial consortium was undertaken on screened municipal wastewater in 24 L pilot reactors. Evaluations of growth and of N and P removal were performed at different Chemical Oxygen Demand (COD) levels and N:P ratios. Lipid accumulation and fatty acid composition of the resulting biomass were also examined. Unique to the present study was the evaluation of wastewater treatment performance under cold temperatures (7–13 °C) typical of a Nordic climate. While temperature exerted little influence on heterotrophic COD removal, vigorous (temperature dependent) growth of microalgae was important in the efficient removal of N and P, with the N:P ratio playing a central role. The studied cultivation regime and organisms achieved regulatory N and P removal levels with a hydraulic retention time (HRT) of 12 days. However, biodiesel properties of the resulting biomass did not meet international standards due to a high proportion of polyunsaturated fatty acids. Possible workarounds for simultaneously increasing nutrient removal efficiency, biomass productivity, and improving biomass suitability for biodiesel under a Nordic climate are discussed.
