Hot Springs and Deep Ocean Thermal Vents
Archaea, Methanogens
- 22 August 1996: Press Release: U.S. and U.K. Researchers have sequenced the genetic information or "genome" of
Methanococcus jannaschii, a single-cell microorganism known as an archaeon (meaning "ancient" in Greek). M. jannaschii is a methane-producing thermophile discovered at the base of a Pacific Ocean thermal vent. This work is sponsored by the U.S. Department of Energy's Microbial Genome Initiative

Oceanic Vents and Hot Springs
Life within/upon "Novel" Substrates
- Rock (endolithic antarctic lichens)
- Ice
- algae which stain ice and snow
- bacteria isolated from the stomachs of frozen mammoths
- Metal (organisms often used in bioremediation)
- Liquid Hydrocarbons (oil-eating bacteria)
- Fossilized amber
Dry (Xerophytic) Environments
- Dessicated organisms which can be revived after long periods
High Radiation Environments
- Bacteria which thrive in nuclear reactors
- Radioresistance of insects
Dark Environments
Life in a Vacuum and in hyper- and hypobaric environments
- Bacteria recovered from Surveyor III camera returned by Apollo 12 crew
after 3 years in a hard vacuum
- Bacteria captured at high altitudes
- Deep Ocean trenches
