Increasing atmospheric carbon dioxide concentration is an important factor in global climate change and the role of other nutrient availability is an important issue regarding microbial responses to increasing carbon dioxide concentration. Studies of changes in cyanobacterial community composition, bloom dynamics, and toxicity in response to increasing temperatures and other environmental factors associated with global warming are of great importance to our understanding of cyanobacterial dynamics. In the current study it was found that phosphate stress inhibited the synthesis of Nitrogen Reductase enzyme. The displacement of an essential metal ion forming the central and functional part of the enzyme protein may be one of the reasons for inhibition of nitrate reductase by heavy metals. NR activity, both in the field and laboratory, are necessary as a contribution, both to understanding algal physiology, as well as to clarify the importance and role of these algae in near-shore biogeochemical cycling.
