FIG 2.

Changes in populations of desiccation-adapted S. Tennessee (A) and S. Eimsbuettel (B) bacteria when exposed for 24 h at 25°C to paenibacterin and polymyxin. Concentrations of paenibacterin are indicated as follows: open square, 0 μg/ml; diamond, 4 μg/ml; filled square, 8 μg/ml; circle, 16 μg/ml. Triangle, 2 μg/ml polymyxin. Each data point is an average of three repeats ± standard deviations. A population count below the method’s detection limit (i.e., <2 log CFU/ml) is indicated by an asterisk (*).
