Abstract

The need to reduce costs associated with the production of microalgae biomass has encouraged the coupling of process with wastewater treatment. Emerging pollutants in municipal, industrial, and agricultural wastewaters, ranging from pharmaceuticals to metals, endanger public health and natural resources. The use of microalgae has, in fact, been shown to be an efficient method in water-treatment processes and presents several advantages, such as carbon sequestration, and an opportunity to develop innovative bioproducts with applications to several industries. Using a bibliometric analysis software, SciMAT, a mapping of the research field was performed, analyzing the articles produced between 1981 and 2018, aiming to identifying the hot topics and trends studied until now. The application of microalgae on water bioremediation is an evolving research field that currently focuses on developing efficient and cost-effective treatments methods that also enable the production of add-value products, leading to a blue and circular economy.

  • Low cost water supplies could include seawater or brackish water or non-potable water where the algae could also serve a bioremediation role.

    “Low cost water supplies could include seawater or brackish water or non-potable water where the algae could also serve a bioremediation role [31].”

    From Key Targets for Improving Algal Biofuel Production (2021) · cites this paper as [31]

    The Introduction (page unavailable) says that cultivating microalgae in wastewater can reduce biomass-production costs while treating the wastewater, supporting the non-potable-water and bioremediation part of the claim. It does not identify seawater or brackish water as low-cost cultivation supplies; seawater appears only in a reference title about bioremediation. (LLM, conf=0.86)

  • Bioremediation is a crucial intervention method utilizing living organisms-primarily bacteria and fungi-to reduce soil and water contaminants.

    “Bioremediation is a crucial intervention method utilizing living organisms-primarily bacteria and fungi-to reduce soil and water contaminants [261].”

    From Harnessing bacterial consortia for effective bioremediation: targeted removal of heavy metals, hydrocarbons, and persistent pollutants (2025) · cites this paper as [261]

    The Introduction describes biological treatment using microalgae to remove pollutants from wastewater, supporting the claim that living organisms can reduce water contaminants. It does not support the claim that bioremediation primarily uses bacteria and fungi or establish its application to soil contaminants; its focus is microalgae and water. (LLM, conf=0.88)

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.
