Method "Bacteria were made competent by the following procedure: 50 ml culture inoculated with 0.5 ml of over-night culture was grown with aeration in medium A (LB broth supplemented with 10 mM-MgSO4 7H2O and 0.2%-glucose) to mid logarithmic phase. The presence of 10 mM-Mg++ in medium stimulates transformation efficiency (ref 3)."
