Occurrence of mycosporine-like amino acids (MAAs) in the bloom-forming cyanobacterium Microcystis aeruginosa
Abstract
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. Our results are the first to clearly document the occurrence of these UV-sunscreen compounds in a freshwater bloom-forming cyanobacterium.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
