Now scientists at MIT have tinkered with its genes to persuade it to make fuel — specifically, a kind of alcohol called isobutanol that can be directly substituted for, or blended with, gasoline.
Christopher Brigham, a research scientist in MIT’s biology department, explains that in its natural state, when the microbe’s source of essential nutrients (such as nitrate or phosphate) is restricted, “it will go into carbon-storage mode,” essentially storing away food for later use when it senses that resources are limited ..>> Read More<<
