Description

Psychrobacter arcticus 273-4. This strain is part of an analysis of the growth of organisms at and their adaption to low temperature, a study that is being conducted by Michigan State University as a member of NASA's Astrobiology Institute. Insight into how these organisms grow and adapt to life in low temperature environments could aid in understanding transport of microbes through space, either as a contaminant on human spacecraft, or as a passenger on an asteroid or comet.
