Carotenoids from marine bacteria: A natural antioxidant and UV protectant

ABSTRACT

For the cosmetics and pharmaceutical sectors, marine resources are a promising supply of organic substances. Marine organisms have evolved particular metabolites to combat threats to their survival, reproduction, and the easier storage, movement, and turnover of essential biological materials in habitats with extreme conditions like high salinity, low temperature, or intense pressure.Several newly conducted research studies on pigments, such as violacein, astaxanthin, canthaxanthin, zeaxanthin, rubrolone, and carotenoid derivatives of bacteria from marine sources, confirm their effective radical scavenging activity. Carotenoids are tetraterpene, lipophilic bioactive pigments synthesized by archaea, algae, photosynthetic bacteria, and plants. Carotenoids are divided into two categories, oxygenated carotenoids (xanthophylls) having oxygen as a functional group, and hydrocarbon carotenoids (carotene) made of carbon and hydrogen atoms Carotenoids are important because of their functional properties, which include their usage in the food industry as color additives and natural antioxidants, as well as chemotaxonomic markers and pharmaceuticals. The present review aims to describe 1) carotenoids from marine bacteria 2) the antioxidant properties of carotenoids 3) the Exposure consequences of ultraviolet radiation 4) the protective role of carotenoids. Photoaging, sunburn, and skin cancer are all possible side effects of excessive UV exposure. Carotenoids have potential use in the pharmaceuticals and cosmetic industry as anti-aging, photoprotective, skin-whitening, anticancer, and immunity boosters because of their antioxidant and UV protection properties.
