Toxin-Gobbling Bugs Could Clean Ocean Dead Zones http://apocadocs.com/s.pl?1229259131
Bacteria that break down toxic compounds may have tricked scientists into underestimating the threat posed by spreading oceanic dead zones. But there's a silver lining: the bacteria might help bring them back to life.
In a 4,200-square-mile Atlantic ocean swath off the coast of Namibia, bacteria converted lethal sulphide into foul-smelling but otherwise harmless sulphur and sulphate.
"This is the first time that large-scale detoxification of sulphidic waters by chemolithotrophs has been observed in an ocean-open system," write European microbiologists and geochemists in a paper published Wednesday in Nature.
