List of Hypergeophilic & Hypergeotolerant Bacterial Genera

Genera containing thermophilic and hyperthermotolerant organisms are marked with an asterisk (*)

Genera containing barophilic and hyperbarotolerant organisms are marked with two asterisks (**)

Genera containing thermobarophilic and hyperthermbarotolerant organisms are marked with three asterisks (***)

Genera containing acidophilic and hyperacidotolerant organisms are marked with a dagger (†)

Genera containing halophilic and hyperhalotolerant organisms are marked with two daggers (††)

Genera containing haloacidophilic and hyperhaloacidotolerant organisms are marked with three daggers (†††)

Genera containing alkaliphilic and hyperalkalitolerant organisms are marked with a double dagger (‡)

Genera containing thermoacidophilic and hyperthermoacidotolerant organisms are marked with an asterisk and a dagger (*†)

Genera containing thermoalkaliphilic and hyperthermoalkalitolerant organisms are marked with asterisk and a double dagger (*‡)

Genera marked with an asterisk and a degree sign (*°) contain endospore-forming polyextremotolerant organisms. Bacterial endospores tend to give the bacteria capable of producing them polyextremotolerance. Endospores are known for being able to survive extremely high doses of radiation, vacuum dessication, extreme heat and cold, lack of nutrients, and in some cases even the passage of hundreds of millions of years (for example, Bacillus strain 2-9-3 was revived by scientists from 250-million-year-old spores (Vreeland, 2000); for comparison, the first dinosaurs began appearing about 220 MYA — 30 million years later). Although these endospore-forming bacteria can survive a variety of harsh conditions, endospore-formation is not done for reproduction, as with fungal spore formation, but is instead a last-ditch effort to survive conditions the bacterium would not otherwise be able to, which means these critters aren’t true polyextremophiles, because they don’t (necessarily) actually grow better in extreme conditions, and in their endospore form don’t even grow at all.
