FIG. 4.
Challenge of P. oleovorans GPo1 (A) and P. oleovorans GPo500 (B) residing in microcosms at 47°C. An exponential culture and cells residing in the microcosms for 3, 10, and 21 days were challenged at 47°C. Percent survival was determined as the number of viable cells at each time divided by the number of viable cells before exposure to heat. The data are means of two independent experiments.
