Microalgae as sustainable cell factories

Abstract

Microalgae and cyanobacteria are sunlight-driven cell factories that convert carbon dioxide to potential biofuels, foods, feeds and high-value bioactives.In addition, these microorganisms are useful in several bioremediation applications and as nitrogen fixing biofertilizers.This work discusses the industrial and environmental applications of microalgae and the production of algae in photobioreactors.Suitably designed photobioreactors are substantially more productive in comparison with open ponds and "raceways" that have been traditionally used for culturing microalgae.Furthermore, photobioreactors allow monoseptic culture of many more algae than can be grown in open systems.Design of photobioreactors requires an ability to accurately estimate the photosynthetic irradiance level; supply the necessary amount of carbon dioxide; remove the inhibitory oxygen produced by photosynthesis; ensure rapid light-dark cycling of cells for enhanced productivity; and limit the maximum level of turbulence that the fragile algal cells are exposed to.These and other aspects of photobioreactor engineering are discussed.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Tubular photobioreactors are often considered the most suitable for commercial large-scale mass cultures due to their large illumination surface area.

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.
