According to my only readily available source ('Energy: a Guidebook' by Janet
Ramage) the combustion of hydrogen releases 37 kWh/kg. That's more than twice
the heat released from methane.
These bacteria are often referred to as being 'magnetotactic',
although not all precipitate magnetite - I've seen one piece of research
in which greigite (Fe3S4) and iron pyrite (FeS2) were precipitated instead.
A good place to start is a paper by Frankel, Blakemore and Wolfe in Science 203, pages 1355-1356, 1979.
There's nothing really that odd about this type of thing if you think about it.
Most organisms which are capable of movement also require some point of reference against which
they can determine their own motion. Such references can include chemical concentration gradients, the sun,
or images of surroundings. Bacteria don't have eyes, and so this last option is not available to them.

As a stick figure, I find your comments offensive.
Anyone who listens to Pink Floyd a lot will know that the is no dark side of the moon - 'matter of fact, it's all dark'.

Why say semi-illiterate? Is there a difference between "semi-illiterate" people and "semi-literate" people?
It depends on whether you're an optimist - one's half full, the other's half empty.
