Growth characteristics of recombinant clone STC. The growth of recombinant clone STC, DH5α transformed with pUC19, and DH5α host strain were analyzed for NaCl tolerance in the LB agar medium. A tenfold serial dilution (from left to right as indicated above panel a) of each strain was spotted on the LB medium (a–f) and LB medium containing ampicillin (g–l) and increasing concentration of NaCl as follows: 0 (a, g), 0.5 (b, h), 0.75 (c, i), 1.0 (d, j), 1.2 (e, k) and 1.5 M (f, l). The medium without NaCl was used as control
