Oil-eating bacteria don’t work in low oxygen water, dead zones


Gulf oil full of methane, adding new concerns, Associated Press, June 18, 2010:

"This is the most vigorous methane eruption in modern human history," Kessler said.

The small microbes that live in the sea have been feeding on the oil and natural gas in the water and are consuming larger quantities of oxygen, which they need to digest food. As they draw more oxygen from the water, it creates two problems. When oxygen levels drop low enough, the breakdown of oil grinds to a halt; and as it is depleted in the water, most life can't be sustained. ...

In an e-mail, Joye called her findings "the most bizarre looking oxygen profiles I have ever seen anywhere."
