over 99% of bacteria or antibiotics aren’t discovered. However‚ recently a new antibiotic called teixobactin was discovered. This antibiotic prevents the synthesis of a cell wall by binding to a motif of lipid II and lipid III molecules. The goal of this experiment was to discover how teixobactin interact with bacteria and how it is able to effectively kill pathogens. A device called the iChip was used to discover teixobactin. The iChip helped to isolate and grow uncultured bacteria. Multiple iChips
