Efficient production of mycosporine-like amino acids, natural sunscreens, in Yarrowia lipolytica
Biotechnology for Biofuels and Bioproducts, 2023 Background Mycosporine-like amino acids (MAAs), including shinorine and porphyra-334, are gaining attention as safe natural sunscreens. The production of MAAs has been achieved in diverse microbial hosts, including Saccharomyces cerevisiae.
