A group of scientists from the United States created a new kind of bacteria. These bacteria can synthesize organic compounds using light due to the fact that they are part of the semiconductor crystals. It is thanks to the presence of semiconductor elements in a living organism bacteria called “bacteria-cyborgs”.
The creation of a special microorganisms are scientists from UC Berkeley, and on the work done became known in the course of the 254-th conference of the American chemical society. For their study, the experts took photosynthetically bacteria Moorella thermoacetica, which in the process of respiration to produce acetic acid. Adding cadmium and cysteine to the culture medium of bacteria, scientists have found microorganisms inside which was attended by nanocrystals of cadmium sulfide. These crystals can function approximately as solar panels. Derived therefore the bacteria was designated the M. thermoacetica-CdS, and crystals of sulphide of magnesium allowed them to synthesize acetic acid from carbon dioxide, water and solar energy.
“Our “bacteria-cyborgs” use the sunlight much more effectively than happens in nature when, say, photosynthesis. In theory with the help of genetic modifications, you can create and other bacteria that produce no acetic acid, and nutrients, biofuels or other useful compounds. The production technology is virtually waste-free”.
It should be noted that this is not the first to make bacteria to produce useful substances. For example, last year a group of scientists from Harvard University led the bacterium is able to convert carbon dioxide and hydrogen in the alcohol-containing substances. But “bacteria-cyborgs” was created for such purposes for the first time.
