Proteomic patterns of S. aciditrophicus as detected by 2D-PAGE. Two-dimensional gel analysis of the S. aciditrophicus proteome for cells grown on benzoate supplemented with crotonate. The x-axis is separated by isoelectric focusing (IEF), whereas the y-axis is separated by SDS-PAGE. Selected proteins present in the spots are listed in Table 2. 2D-PAGE, two-dimensional polyacrylamide gel electrophoresis.
