The wild-type (blue circles) and ΔglgC mutant (orange squares) cyanobacteria were cultured using media with the initial nitrate concentration of 7.5 mM (low nitrogen, LN) and 17.6 mM (high nitrogen, HN). Subsequently, extracellularly released metabolites in glycolysis and the TCA cycle (a) and proteinogenic amino acids (b) were analyzed. Pyr pyruvate, Lac lactate, 2-OG 2-oxoglutarate, Suc succinate, Fum fumarate, Mal malate, Ala alanine, Arg arginine, Asn asparagine, Asp aspartate, Cys cysteine, Gln glutamine, Glu glutamate, Gly glycine, His histidine, Ile isoleucine, Leu leucine, Lys lysine, Met methionine, Phe phenylalanine, Pro proline, Ser serine, Thr threonine, Trp tryptophan, Tyr tyrosine, Val valine. Values are shown as the mean ± standard deviation of three replicate experiments (*P < 0.05 by Welch’s t test).
