Astrobiology Laboratories

Astrobiology Laboratories

Microbiological safety cabinets with gloves

The astrobiology facilities are furnished with standard equipment used to isolate and culture aerobic microorganisms; microbiological safety cabinets, autoclaves, microscopes, and an incubator room.

What makes these laboratories stand out are our anaerobic microbiology capabilities. We have a gas purging station for creating anaerobic growth media, a separate dedicated anaerobic gas mix for charging Wheaton tube headspace, and both Don Whitley and Coy anaerobic chambers for inoculating and sub-culturing anaerobic microorganisms.

Our most recent addition to the laboratories is a series of MicrobeMeters used to determine the optical density of anaerobic microorganisms in-situ.

Molecular Biology Laboratories

Many samples analysed in the Astrobiology Laboratories originate from extreme environments across the world. Extracting nucleic acids from these habitats takes patience and a great deal of method development.

To prevent cross-contamination our facilities separate out nucleic acid extraction, PCR preparation and PCR into three distinct areas.

Coming soon: a facility dedicated to extracting nucleic acid from low-biomass environments.

Equipment of interest includes:

  • FastPrep24 and FastPrep24 5G homogenisers;
  • SpeedVac SPD130 vacuum concentrator;
  • Qiagen’s BLU-V system;
  • Various PCR machines including gradient PCR;
  • QuantStudio 3 real-time qPCR machine;
  • NanoDrop OneTM UV-Vis spectrophotometer;
  • QubitTM 2 fluorometer;
  • Gel Doc HR+ gel documentation system;
  • Invitrogen™ Novex™ WedgeWell™ protein electrophoresis system.

Environmental simulation chambers

Environmental simulation chambers are used to reproduce, as far as possible, the near- and sub-surface environments of Mars and the icy moons of Europa and Enceladus.

The continuous flow-through reactors allow researchers to sample the chemistry and/or the microbiology of these systems under a range of different temperatures and pressures.

We currently have four reactors, the specifications of which can be found below.

Alongside the continuous flow-through reactors, we have a range of static reactors which are used to analyse the chemistry of various regolith compositions and water-rock interactions.

Haskel air intensifiers are used to increase the pressure achievable from a standard 200bar gas cylinder to a high 345bar, which would be the equivalent of simulating the pressures at a depth of 3.5km beneath the surface of Mars.

Finally, in this facility we have a Swagelok gas mixing station for bespoke gas mix make up for use in the simulated environmental chambers.
