ABRIL-IBARRA, Zulay. Antioxidants produced by aquatic and terrestrial microorganisms with potential use in cosmetics. Actu Biol [online]. 2022, vol.44, n.116, e2.  Epub May 24, 2022. ISSN 0304-3584.  https://doi.org/10.17533/udea.acbi.v44n116a02.

Antioxidants are natural or synthetic compounds capable of preventing or delaying oxidative damage, by counteracting free radicals in biomolecules exposed to this type of stress. The food, pharmaceutical and cosmetic industry has replaced chemical ingredients with natural compounds, using substances obtained from plants. However, the greatest source of natural resources is in microorganisms, due to their great diversity and the metabolic mechanisms they have developed to adapt to areas with unfavorable environments. The microorganisms that produce compounds useful for humans that are included in the review are: fungi, bacteria, and microalgae. The most explored microorganisms are those that inhabit terrestrial environments due to their accessibility, however the extensive marine environment also harbors a great diversity of organisms from which several compounds such as carotenoids, flavonoids, phenols or exapolysaccharides to applied in cosmetic industry. This article presents a review of 90 articles published between 2015 and 2020 with relevant information about antioxidants produced by aquatic and terrestrial microorganisms with potential use in cosmetics, to provide relevant information about alternatives to artificially or plants synthetized antioxidants.

Keywords : Natural compounds; bacteria; oxidative stress; mushrooms; microalgae; free radicals.
