摘要

Terrestrial bacteria have evolved to tolerate and flourish in many extreme environments, such as the deep ocean, but less is known about microbial responses to low-pressure environments. Wayne Nicholson et al. (pp. 666-671) obtained four core samples of permafrost soil-a cold, low-pressure, anoxic environment-from northeastern Siberia, and cultured each sample for up to 28 days on nutrient-rich agar plates incubated at room temperature with ambient air and pressure.
