Comparison of abundance of selected lipid species detected in cells of Synechocystis sp. PCC 60803 cultivated in FGM and in SGM. Fold-changes were calculated by dividing the average peak area of a given lipid species detected in samples obtained in FGM (n = 6) by the average peak area of the same lipid species detected in samples obtained in SGM (n = 6). The log2 fold-change values are presented: positive values correspond to higher peak area in FGM compared to SGM, while negative values represent peak areas higher in SGM in comparison to FGM. Mann-Whitney unpaired analysis, * p < 0.05, ** p < 0.01, *** p < 0.005, ns: not statistically significant difference.
