Nitrogen Availability Affects the Metabolic Profile in Cyanobacteria.

ABSTRACT: Nitrogen is essential for the biosynthesis of various molecules in cells, such as amino acids and nucleotides, as well as several types of lipids and sugars. Cyanobacteria can assimilate several forms of nitrogen, including nitrate, ammonium, and urea, and the physiological and genetic responses to these nitrogen sources have been studied previously. However, the metabolic changes in cyanobacteria caused by different nitrogen sources have not yet been characterized. This study aimed to elucidate the influence of nitrate and ammonium on the metabolic profiles of the cyanobacterium Synechocystis sp. strain PCC 6803. When supplemented with NaNO₃ or NH₄Cl as the nitrogen source, Synechocystis sp. PCC 6803 grew faster in NH₄Cl medium than in NaNO
