Abstract

Microalgae have become an attractive natural source of a diverse range of biomolecules, including enzymatic and non-enzymatic antioxidants; nevertheless, economically sustainable production of such compounds from microalgae biomass is still challenging. The main hurdles are: (a) increasing microalgae yield; (b) achieving optimal cultivation conditions; (c) energy-efficient and cost-effective downstream processing (extraction and purification); (d) optimal storage of post-processed antioxidant molecules. This review provides a detailed overview of enzymatic and non-enzymatic antioxidants in the cellular metabolism of the commercially important microalgae Dunaliella, industrial applications of antioxidant enzymes, strategies to enhanced antioxidant accumulation in cells, and the opportunities and limitations of current technologies for antioxidant enzymes production from microalgae biomass as an alternative to common microbial sources.

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?

  • Algae that grow in brackish or highly saline media require additional NaCl, such as Dunaliella.

    “Algae that grow in brackish or highly saline media will require additional NaCl, such as Dunaliella [36].”

    From Key Targets for Improving Algal Biofuel Production (2021) · cites this paper as [36]

    The Introduction says Dunaliella grows across a wide range of NaCl concentrations and that most identified species inhabit saline environments. Cultivation Conditions describes using natural or artificial seawater, but does not say that additional NaCl must be added; the Introduction also notes five freshwater species.

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.
