iron-eating bacteria

Hello Ron,

here is another one.


Gerrit Voordouw, PhD, a microbiologist at the University of Calgary, has
spent the past 20 years trying to unlock the secrets of an iron-eating
bacteria known as Desulfovibrio vulgaris.
This potent microbe, found in oil and gas reservoirs, can eat its way
through a pipeline in just a few months. "We wanted to understand why D.
vulgaris is so corrosive to pipelines and oilfield equipment," says
Voordouw. " And we knew that the key was to sequence its 3,394 genes."<

(...)

Genetic research tries to answer three fundamental questions:
where is a gene located within the entire blueprint?
which proteins are produced and what do they do?
how active is the gene?


Later,

Dear Lee,
Iron plays a crucial roll in the geological history of the Earth and
the creation of an Oxygen rich atmosphere. I think you would need to
seek out the commentaries for the geological surveys of the places
where Spanish RIO is mined to confirm that. Our nearby Iron Ore
deposits are said to have formed well over 2, possibly 3 billion years
ago. Some of the microscopic features in some Iron Jaspilite Rocks
have been identified as having the characteristics of Bacteria.
So your supposition could be true.
Best regards,
Ivor

Isn't bacteria responsible for the creation of Spanish Iron Oxide?

Ivor,

Been having computer problems, but I think I got them fixed.
