Role of Microalgae in the Recovery of Nutrients from Pig Manure

摘要: Animal production inevitably causes the emission of greenhouse gases and generation large amounts slurry, both representing a serious environmental problem. Photosynthetic microorganisms such as microalgae cyanobacteria have been proposed alternative strategies to bioremediate agricultural waste while consuming carbon dioxide producing valuable biomass. The current study assessed potential microalga Scenedesmus sp. remove nutrients from piggery wastewater (PWW) influence on microbial consortia. Maximum N-NH4+ consumption was 55.3 ± 3.7 mg·L−1·day−1 P-PO43− removal rates were in range 0.1–1.9 mg·L−1·day−1. partially caused by action nitrifying bacteria, which led N-NO3−. N-NO3− values where lower when more active. This work demonstrated that photosynthetic activity allows us increase nutrient PWW reduce coliform bacterial load effluent, minimising their impact health risks. Microalgae assimilated part present media produce biomass did not convert it into traditional processes.
