Geoscience Module 1 Bacterial Diversity 0 MTBE is a gas additive that was used to reduce smog in reformulated gasoline 0 Used to cause water to set fire right out of the tap 0 Removed from use eventually and its smogfighting abilities were replaced by ethanol 0 Is found in water after leaks much more often because it dissolves better than toluene and benzene 0 A study was done with MTBE to observe microbes 0 Scientists took sediment containing microbes from the area where MTBE leaked and injected the additive into it 0 Since MTBE releases carbon dioxide as it breaks down the amount of carbon dioxide after a time showed how much of the additive had been destroyed I If oxygen was present between 30 and 73 of the additive was destroyed within 100 days I The microbes were responsible for this because MTBE did not break down in sediments where the microbes were not present scientists killed off the microbes in these sediments using heat 0 Scientists are now trying to identify these microbes responsible which could lead to the development of bioreactors could clean up leaking tanks elsewhere 0 It is unclear how many underground leaking gas tanks contain MTBE and while the government could prevent future leaking the current pollution could still affect groundwater for years to come 0 There are so many prokaryotes in the world organisms that lack a nucleus and they live everywhere from the upper atmosphere and bottom of the ocean to indie the human gut O The vast majority of all prokaryotes live under ground or in the ocean oor 0 Scientists have tried to predict the number of prokaryote on earth by taking scientific literature on the density of prokaryotes in certain habitats forests sea oor fresh waters etc and multiplying it by that habitat39s area in earth 0 No real way to crosscheck this data because sources are so limited 0 There is an astonishing amount of diversity in prokaryotes almost an immeasurable amount 0 This stems from successful mutations changes in genetic structure and allows the organisms to prosper in almost every environment They reproduce much faster than larger organisms and thus can mutate and create generations faster evolution occurs faster
