FIG. 2.

Two-dimensional gel electrophoresis of soluble proteins (supernatant obtained after centrifugation at 100,000 × g) of T. aromatica anaerobically grown on 4-hydroxybenzoate (A) and phenol and CO₂ (B). Triangles indicate phenol-induced proteins. F1 to F5 were isolated and their N-terminal amino acid sequences were determined.
