Profiling of mycosporine-like amino acids (MAAs) in wild Hypnea spp. and semi-closed cultivated Hypnea musciformis (Gigartinales, Rhodophyta) from the Colombian Caribbean

Results in Chemistry
Mycosporine-like amino acids are marine natural products with significant ultraviolet radiation absorption capacity, positioning them as promising candidates for the cosmetic industry. This study aims to evaluate the MAAs content in wild-type Hypnea spp.

Effects of light qualities on the growth and porphyra-334 (a mycosporine-like amino acid) biosynthesis capacity of Effrenium voratum

Abstract Symbiodiniaceae synthesizes bioactive substances like mycosporine-like amino acids (MAAs). To date, there has been little knowledge about the effects of light qualities on the growth and bioactive substance synthesis capacity of Symbiodiniaceae .

Marine Algae Extract-Loaded Nanoemulsions: A Spectrophotometric Approach to Broad-Spectrum Photoprotection

Cosmetics
The depletion of the ozone layer and climate change have increased exposure to ultraviolet (UV) radiation, driving the search for natural photoprotective agents. Marine macroalgae, particularly Gracilaria sp.

Fotoprotección antioxidante no-enzimática contra el potencial daño inducido por UVBR en una diatomea antártica (Thalassiosira sp.) Non-enzymatic antioxidant photoprotection against potential UVBR-induced damage in an Antarctic diatom (Thalassiosira sp.)

Latin American Journal of Aquatic Research, 2011
In January 1999, unialgal cultures of the diatom Thalassiosira sp., solate from natural phyto-plankton assemblages from Potter Cove, Antarctica, were exposed to solar ultraviolet radiation (UVR, 280400 nm) in order to study the long-term acclimation of ...

Glycosylated porphyra-334 and palythine-threonine from the terrestrial cyanobacterium nostoc commune

Glycosylated porphyra-334 and palythine-threonine from the terrestrial cyanobacterium nostoc commune
Mycosporine-like amino acids (MAAs) are water-soluble UV-absorbing pigments, and structurally different MAAs have been identified in eukaryotic algae and cyanobacteria. In this study novel glycosylated MAAs were found in the terrestrial cyanobacterium Nostoc commune (N. commune).
