MIT Chemists Harness Bacteria to make Biofuel, Soak up Pollutants

When we think of microbes, few if any good thoughts come to mind. But leave it up to the scientists at the MIT, and these microscopic organisms become a benefit to the environment.
With W.H. Dow Professor of Chemical Engineering Gregory Stephanopoulos and Assistant Professor Kristala Jones Prather at the helm, MIT sees bacteria as diverse and complex "chemical factories" that can revolutionize the production of biofuels and other compounds. Prather, for her part, is developing bacteria that can forge butanol and pentanol from agricultural byproducts, while Stephanopoulos is trying to make better microbial producers of biofuels by improving their fermented feedstock's toxicity tolerance.
But that's not all. The extent of bacteria's green gains goes much
farther, says chemistry professor Catherine Drennan, who hopes to one
day use it to soak up toxins such as carbon monoxide and carbon dioxide
from the Earth's atmosphere. The microbes she found in various natural
habitats actually break down harmful pollutants and could help remove
them from Earth's lower atmosphere. "These bacteria are responsible for
removing a lot of CO and CO2 from the environment," she said. "Can we
use this chemistry to do the same thing?"
Cryptocurrencies have opened up a whole new world of opportunities in the financial markets. They have been touted as the currency of the future. This new form of currency has already permeated the market, and many smart traders are making a pretty penny off the different types of cryptocurrencies. As you are aware, traders who invested in Bitcoin back in 2009 got ROIs thousands of times their initial investments. You, too, should consider taking advantage of the cryptocurrency craze. Read more
Color photographs appeared in the middle of the XIX century but were available only to a very narrow privileged circle of people. Therefore, it is normal if the family stores black and white photographs of relatives of those years. Many even like to review them again and again as old cards can awaken special feelings and memories, transfer through time. Read more
Search Engine Optimization or SEO is the process of optimizing websites in order to achieve better results and higher ranks in search engine results. Search engines like Google, Yahoo and Bing depend on certain algorithms that help rank websites according to the way they have been optimized for readers and viewers. Read more
