Abstract

In response to the energy crisis, global warming, and climate changes, microalgae have received a great deal of attention as a biofuel feedstock. Due to a high lipid content in microalgal cells, microalgae present as a promising alternative source for the production of biodiesel. Environmental and culturing condition variations can alter lipid production as well as chemical compositions of microalgae. Therefore, application of the strategies to activate lipid accumulation opens the door for lipid overproduction in microalgae. Until now, many original studies regarding the approaches for enhanced microalgal lipid production have been reported in an effort to push forward the production of microalgal biodiesel. However, the current literature demonstrates fragmented information available regarding the strategies for lipid production improvement. From the systematic point of view, the review highlights the main approaches for microalgal lipid accumulation induction to expedite the application of microalgal biodiesel as an alternative to fossil diesel for sustainable environment. Of the several strategies discussed, the one that is most commonly applied is the design of nutrient (e.g., nitrogen, phosphorus, and sulfur) starvation or limitation. Other viable approaches such as light intensity, temperature, carbon dioxide, salinity stress, and metal influence can also achieve enhanced microalgal lipid production.

  • pH, salinity, and mineral salts are major stimuli affecting lipid production.

    “Besides these factors, pH, salinity, and mineral salts are also major stimuli affecting lipid production (Zhu et al. 2016).”

    From Production of microalgae with high lipid content and their potential as sources of nutraceuticals (2023) · cites this paper as Zhu et al. 2016

    Section 3.5 (Salinity Stress; page unavailable) reports that salinity stress can increase microalgal lipid content, and section 3.6 (Metal Stress; page unavailable) reports effects of mineral ions on lipid production. Section 3.3 (Carbon Dioxide; page unavailable) mentions pH only as a consequence of excess CO2; it does not identify pH itself as a major stimulus affecting lipid production. (LLM, conf=0.85)

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.
