  • a PA number, protein short name, and description are shown according to the Pseudomonas database (www.pseudomonas.com).

  • b Shown are the ratios of the amount of proteins from a P. aeruginosa PAO1 culture incubated for 7 days under pyruvate fermentation conditions at 37°C in phosphate-buffered LB medium to the amount of protein in a culture grown under aerobic conditions (see Materials and Methods). Proteins were separated by 2D gel electrophoresis and stained with RuBPS (see Materials and Methods for details). Protein ratios of 2D gel images were determined by the Z3 software (Compugen, Tel Aviv, Israel). “Unmatched” describes a protein spot which is detected only in the protein pattern of the pyruvate fermentation culture.
