Cover Story: Microalgae and cyanobacteria have been proposed as alternative strategies to bioremediate agricultural waste while consuming carbon dioxide and producing valuable biomass. The current study assessed the potential of the microalga Scenedesmus sp. to remove nutrients from piggery wastewater and the influence of the microalga on the microbial consortia. This work demonstrated that the photosynthetic activity of microalgae can increase nutrient removal rates, minimizing both their environmental impact and health risks. Microalgae assimilated part of the N-NH4+ present in the media to produce biomass and did not convert it into N-NO3- as in traditional processes. View this paper
