Vents thermophilic bacteria

In the same year, Miller and the biologist Antonio Lazcano (National Autonomous University of Mexico) spoke out against hypotheses that life could have originated at hydrothermal vents. They believe that the presence of thermophilic bacteria (the oldest life forms) does not prove that biogenesis occurred in the depths of the oceans. Stanley Miller sees a greater chance for successful pre-biotic chemistry under the conditions of a cold primeval Earth rather than at high temperatures in hydrothermal regions (Miller and Lazcano, 1995).

Around the hydrothermal vents in the deep sea, extremely thermophilic bacteria reside which have the optimal growth temperature at 100°C which participate in the reduction of several metals. For example, Pyrobaculum islandicum (Kashefi...

Thermophilic microbes have been known for some years from the hot springs of Yellowstone National Park, USA (Farmer, 2000) but now are also documented from deep ocean hydrothermal vents, the most extreme of which is an Fe(III)-reducing member of the Archaea that can grow at 121°C (Kashefi St Lovley, 2003). Ocean vent microbial communities are diverse and include Archaea and Bacteria (Hoelc et al., 2003) which utilize hydrogen- and iron-oxidizing and sulfur-reducing metabolisms to produce microbial mats. They form rod-like, coccoid, and filamentous forms (Reysenbach and Cady, 2001). An equally diverse array of thermophilic microbes is also...
