Breakthroughs Today

Using more than 200 samples collected from 17 deepwater sites between May 25 and June 2, scientists led by Terry Hazen reported on 24 August 2010 that they found a dominant microbe in the oil plume which turned out to be a new species, closely related to members of Oceanospirillales . It thrives in cold water, with temperatures in the deep recorded at 5 degrees Celsius (41 Fahrenheit). Scientists from the Lawrence Berkeley National Laboratory noticed this suddenly flourishing bacteria at the oil spill in the Gulf of Mexico. Although still unknown and unnamed, the microbe consumed oil droplets found underwater without significantly depleting oxygen in the water. Oxygen saturation outside the oil plume was 67 percent, while that within the plume was still 59 percent. Oil-eating microbes that consume large amounts of oxygen in the water can potentially create a "dead zone," an area where no oxygen was available, which is dangerous to other life underwater.
