Production of mycosporine‐like amino acid (MAA)‐loaded emulsions as chemical barriers to control sunscald in fruits and vegetables

Journal of the Science of Food and Agriculture, 2021
AbstractBACKGROUNDSunscald is a physiological disorder that occurs in many horticultural products when exposed to excessive solar radiation and high temperatures. Traditionally, sunscald is controlled using physical barriers that reflect radiation, however this practice is not always efficient.

Occurrence of mycosporine-like amino acids (MAAs) in the bloom-forming cyanobacterium Microcystis aeruginosa [PDF]

Journal of Plankton Research, 2004
Here we report the finding of two mycosporine-like amino acids (shinorine and Porphyra-334) in both a culture of the cyanobacterium Microcystis aeruginosa isolated from Lake Taihu (China) and a natural phytoplankton sample collected from this lake which included Microcystis spp.
