Assay
Liquid cultures of negative control and otsAB transformed NEB5α E. coli were grown up over night at 37°C. After incubation, a dilution spot assay was conducted on each of the cultures to determine the density of live cells. Next, 15 5cm, round petri dishes were filled with 300uL of negative control bacteria, another 15 with transformants containing MntH, another 15 with transformants containing betAB, and another 15 with transformants containing otsAB. The petri dishes were allowed to desiccate while covered for 24 hours at 37°C while shaking. After the 24 hours period, each plate was resuspended with 1mL of fresh LB. A dilution spot assay was then conducted on each of the petri dish to determine the final density of live cells.

Results

Applications of BBa_K847060

Astrobiology revolves around three central questions: "Where do we come from?", "Where are we going?", and "Are we alone?" To approach the second question, the Hell Cell subgroup of the Stanford-Brown iGEM team developed BioBricks that allow a cell to survive harsh extraterrestrial conditions. Such a toolset could create a space-ready synthetic organism to perform useful functions off-world. This gene is one of the toolset, potentially conferring desiccation resistance to otherwise intolerant bacteria.
