Summary
Investigations of the bloom-forming arctic diatom Thalassiosira antarctica COMBER show that at all temperature and light conditions tested, the 14C-incorporation rates in lipids averaged 20% and in carbohydrates 12%. The percentage of 14C in proteins and small metabolites ranged from 30% to 50% respectively, with contrary trends. The production rate of protein per generation time was not temperature and light dependent. The changes in percent carbon incorporated into proteins may be due to enhanced metabolite synthesis at high irradiances and/or temperatures above 0° C.
