Identifying microbial species
Millions of microbial species populate the world, but so far only a few have been identified due to the inability of most microbes to grow in the laboratory. Edgar Goluch, an engineer, and Slava Epstein, a biologist, aim to change this. The pair, both researchers at Northeastern University, has developed a device that allows scientists to cultivate a single species of bacteria that can then be studied and identified.
Goluch’s previous research devices incorporated permeable membranes that allow sequestered bacteria to be exposed to the nutrients and molecules of their native environment. But natural competition between species, even in the wild, has so far limited the number of species of bacteria that biologists have been able to isolate with these methods and in traditional lab settings.
