Figures & Tables

Figure 1

Survival of air-dried cells of S. aureus (circles) and S. epidermidis (triangles) as a function of time. Data points are averages ± standard deviations of duplicate samples.

Figure 2

Pre-SVT growth curves of S. aureus (A) and B. subtilis (B) in 60 mm Petri plates. Data are averages + standard deviations of duplicate experiments. Growth phases are denoted: (i) lag, (ii) logarithmic, (iii) transition, and (iv) stationary. Data are plotted on the same scales for comparison.

(A) Actuation of BRIC-23 canisters onboard the ISS by astronaut Jeffrey Williams. (B) Temperatures recorded during BRIC-23 flight for B. subtilis (HOBO-A, green line) and S. aureus (HOBO-D, red line). Time of actuation is denoted by upward arrow, and time of canister transfer to the onboard −80°C freezer is denoted by the downward arrows.
