Microalgae strains isolated from piggery wastewater in Ecuador: Effective nitrogen compound removal and growth potential in extremophile conditions.

ABSTRACT: Effluents generated by anthropogenic activities are a significant source of pollution and eutrophication in natural water bodies. In Ecuador, the increase in pig production has exacerbated this issue due to the untreated discharge of pig effluents. This study focused on the characterization of native microalgae present in pig effluents and the evaluation of their capacity to remove nitrogenous compounds under various conditions, with the aim of identifying efficient strains for phycoremediation. Four microalgal strains were isolated and molecularly identified as Radiococcus polycoccus, Chlorolobion braunii, Micractinium sp., and Desmodesmus multivariabilis. The cultures were exposed to initial concentrations of 100 mg L^-1 N-NH₄ and 49.97 mg L^-1 N-NO₃ for
