Biological removal of nitrogen oxides by microalgae, a promising strategy from nitrogen oxides to protein production

Abstract

Nitrogen oxides (NO x) are the components of fossil flue gases that give rise to serious environmental and health hazards. Among the available techniques for NO x removal, microalgae-based biological removal of NO x (BioDeNO x) is a promising and competent technology with eco-friendly path of low energy and low-cost solution for the pollution. In this review article, current biological technologies including bacteria-based and microalgae-related BioDeNO x are discussed. Comparing to direct BioDeNO x approach, indirect BioDeNO x by microalgae is more promising since it is more stable, reliable and efficient. By transforming inorganic nitrogen nutrients to organic nitrogen, microalgae can potentially play an important role in converting NO x into high-value added products. The microalgae-based BioDeNO x process displays an attractive prospect for flue gas treatment to reduce environmental NO x pollution and potentially supply protein products, establishing an efficient circular-economy strategy.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
