Microalgae cultivation: photobioreactors, CO 2 utilization, and value‐added products of industrial importance
Abstract
Abstract Increasing world population, industrialization, and economic development demand more energy at a global scale, and this challenge is being met with the exploitation of fossil fuels that cause CO 2 and CH 4 emissions and contribute towards earth's rising temperature. Microalgae are considered potential sources for CO 2 abatement and for combating food insecurity by ensuring a nutritional food supply for the sustainable living of an increasing population. The CO 2 utilization potential of microalgae has been continuously researched for augmentation through various photobioreactor and open raceway pond designs and developments. Apart from recognition for their nutritional importance, microalgae are finding the place in the market as ‘functional foods’ due to their bioactive components. In view of this, the present study highlights the status and current attempts being made for photobioreactor development, CO 2 sequestration, and the production of industrially important microalgal metabolites. This review also explains the factors responsible for microalgal growth and provides research needs and recommendations to make microalgal CO 2 sequestration and value‐added compounds production an industrially competitive process. © 2021 Society of Chemical Industry (SCI).

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.
