Carbon and nitrogen acquisition of the diazotroph Trichodesmium in a high CO2 world

Abstract

The main motivation for this thesis was to describe the responses of the N2 fixing cyanobacterium Trichodesmium to elevated pCO2 and to provide a detailed understanding of underlying processes. The focus was hereby to characterize inorganic carbon acquisition and its interaction with photosynthesis and N2 fixation. Based on these findings, the potential influence of Trichodesmium on the ecosystem and elemental cycles in the future oceans was assessed.
