However, this is just the tip of the iceberg. This new antibiotic was discovered using a new chip developed by a team in Northeastern University in Boston, Massachusetts, that made it possible to culture microbes that previously were impossible to grow in laboratory conditions.
99 percent of soil microbes could originally not be cultured in a laboratory, which made the number different microbes available for study quite small compared to what existed in the wild. Now an additional great number of microbes can be cultured and analyzed to see how they fight off bacteria, and Teixobactin is the first find in this research.
