FIG. 1.

Growth in LB plus 0.2% arabinose (open symbols) or glucose (closed symbols) of MGM100 plasmid transformants at 37°C. Cultures grown overnight on LB plus arabinose were diluted 1:1,000 into LB plus arabinose or glucose. Shown are data for pBR325 (triangles) and pHsp60-Hsp10 (circles). All cultures were diluted 10-fold into a prewarmed medium 140, 225, and 325 min after inoculation to maintain exponential growth, except for the MGM100(pBR325) glucose culture, which was diluted only at 140 min.
