ULTRAVIOLET RADIATION INDUCED CHANGES IN THE PRODUCTION OF ORGANIC COMPOUNDS IN ANTARCTIC MARINE PHYTOPLANKTON
Ocean to examine the impact of enhanced solar ultraviolet-B radiation (UVBR) on the biosynthesis and composition of organic compounds in Antarctic marine phytoplankton. Our results revealed distinct changes in the biochemical composition of phytoplankton attributable to UVBR exposure. Fatty acid con...
