Comparative genomic maps of the JM101 and PB12 strains. Deletions detected in the PB12 strain. The small deletion is the result of the elimination of the PTS genes (ptsH, ptsI and crr) that was previously generated in the parental PB11 strain [7,9]. The largest of these deletions appeared during the laboratory adaptive evolution process (Figures 3 and 4).
