FIG. 7. Resistance to DCS in E. coli carrying ALR and/or
DDL. The survival (%) by a given concentration of DCS was
expressed as a ratio of E. coli harboring each plasmid grown in
the presence of DCS to the same cells grown in the absence of
DCS. The cell growth was monitored as A[600 nm]. A, plasmids
carrying alrS and K12alr are shown as open and closed triangles,
respectively. B, plasmids carrying ddlS, ddlA, and ddlB are
shown as open squares, closed squares, and closed diamonds,
respectively. C, plasmids carrying alrS-ddlS, K12alr-ddlA, and
K12alr-ddlB are shown as open diamonds, closed squares, and
closed diamonds, respectively. E. coli harboring pET-21a(+) was
used as a control strain (A-C, closed circles).
