Indians find bacteria in extreme stratospheric
Tuesday, March 24, 2009

Extreme residents of the highest air are not extraterrestrial, but interesting for biotechnology.



Germs are everywhere really. Up to the highest layers of the atmosphere. Last week began an Indian, stratosphere at forty miles three unknown species of bacteria.

The Indians gave them the names Janibacter hoylei (by the astronomer Fred Hoyle, who once suggested that the flu virus came from space), Bacillus isronensis (to their own research, ISRO) and Bacillus aryabhata (the famous Indian astronomer Aryabhata). These three species can apparently long life in extreme low temperatures and in extremely thin air. And they have no problems with the UV radiation from the sun that are normally lethal for bacteria.

The Indian researchers had eight years ago to stratospheric bacteria 'fish', but the experiment repeated under more stringent conditions (such as the already high level of freezing the bacterial samples) to ensure that the samples on down not 'contaminated' get bacteria at lower altitudes around float.

The Indians suggested that they might find an extraterrestrial origin, but that chance is very small. That makes this near-space vessels are no less interesting. Biotechnologist are always looking for genes that protect against extreme life circumstances, and there seem ample protection.
