“…The 347-Da MAA with an absorption maximum at 333 nm ( It has been reported that 4-deoxygadusol is a common precursor for the biosynthesis of MAAs [20,25,49]. The 4-deoxygadusol could conjugate with a nitrogen substituent (e.g., amino acids) to generate MAAs [20,26,27].…”

Highlights: Glycosylated MAAs have been characterized in two genotypes of Nostoc commune. The A genotype produces β-Ara-porphyra-334 (478 Da) with λ max at 335 nm. The B genotype produces the hybrid MAA (1050 Da) with λ max at 312 nm. 2 AbstractMycosporine-like amino acids (MAAs) are UV-absorbing pigments, and structurally unique glycosylated MAAs are found in the terrestrial cyanobacterium Nostoc commune. In this study, we examined two genotypes of Nostoc commune colonies with different water extract UV-absorption spectra. We found structurally distinct MAAs in each genotype. The water extract from genotype A showed a UV-absorbing spectrum with an absorption maximum at

“…Several marine organisms, notably photosynthetic organisms, produce UV-absorbing compounds such as scytonemins (cyanobacteria), mycosporines, mycosporine-like amino acids (MAAs), and carotenoids to protect themselves from UV radiation [66][67][68][69]. Moreover, despite their large contribution to marine biodiversity and biomass, the UV filters produced by microbial components have been poorly investigated.…”

Abstract:Marine resources represent an interesting source of active ingredients for the cosmetics industry. Algae (macro and micro) are rich in proteins, amino acids, carbohydrates, vitamins (A, B, and C) and oligo-elements such as copper, iron and zinc. All those active principles play roles in hydration, firming, slimming, shine and protection. Marine organisms inhabit a wide spectrum of habitats. Photo-protective compounds can be obtained from organisms subjected to strong light radiation, such as in tropical systems or in shallow water. In the same way, molecules with antioxidant potential can be obtained from microorganisms inhabiting extreme systems such as hydrothermal vents. For example, marine bacteria collected around deep-sea hydrothermal vents produce complex and innovative polysaccharides in the laboratory which are useful in cosmetics. There are many properties that will be put forward by the cosmetic industries.

“…A photo-protective role of scytonemin has been shown (Garcia-Pichel et al, 1992;Dillon & Castenholz, 1999;Gao &Garcia-Pichel, 2011) andCastenholz (1991) reported that scytonemin prevents up to 90% of solar UV radiation from entering the cell. In addition, scytonemin has antioxidant activity and functions as a radical scavenger to prevent cellular damage resulting from reactive oxygen species produced upon UV-radiation exposure (Matsui et al, 2012;Rastogi et al, 2015).…”
