  1. aQuantification of metabolites according to GC-MS analysis. Values refer to area-substrate peak relative to the area-ribitol peak [20 nM] and are mean of three independent experiments.
  2. bStudents’ t-test. Values were calculated by comparing relative quantification measured in extract from stressed cells (either 60 mM NaCl or 110 mM sucrose) with that performed in cells growing under non-stress condition. p < 0.05 was considered as statistical significance and values are shown in bold and italic.
