The ß-dimethylsulphoniopropionate (DMSP) Content of Macroalgae from Antarctica and Southern Chile

It is of interest to determine the levels of DMSP in extreme cold water algae from polar regions such as Antarctica and the Southern Ocean, because low molecular weight organic compounds known to act as osmolytes under salinty stress may well be suitable as protectants under low temperatures stress. Comparison of the values obtained from polar species with those published for algae from temperate regions may point to the effect of temperature on DMSP metabolism
