Low temperature sequestration of photosynthetic pigments: Model studies and natural aquatic environments
… porphyrins. Sediment samples from an Antarctic marine core were submitted to extraction by acetone and acid methanolysis and extracts analysed by LC-MSn. Acid extraction liberated appreciable amounts of tetrapyrroles believed to have been bound via ester linkages to components of the sediment …
