  1. Dps: Bacterioferritin, p19: 19 kDa periplasmic protein, AhpC: Alkyl hydroperoxide reductase, SodB: Superoxide dismutase (Fe), TrxB: Thioredoxin-disulfide reductase, Cj0706: hypothetical protein, MogA: Molybdenum cofactor biosynthesis protein.
  2. Columns: light grey: control (C), dark grey: HCl stressed cells (HCl), white: Acetic acid stressed cells (Ac).
  3. 1 Identification was based on Mascot MS/MS Ion Search using sequence data from the database NCBInr.
  4. 2 Mowse Score (Score).
  5. 3 The intensity of the induced proteins was estimated by Image MasterTM 2D Platinum and % volume intensity was calculated.
  6. The intensity of the protein spots was analyzed using the Image MasterTM 2D Platinum (version 5.0, Amersham Biosciences, Melanie). Three biological independent replicates was performed and % volume intensity was calculated as: % volume intensity control (protein x) = volume intensity /(volume intensity control + volume intensity HCl + volume intensity acetic acid).
