The secondary metabolite-producing properties of microbes are of particular interest in medical and environmental drug discovery. Due to evolving scientific techniques and increasing presence of drug-resistant bacteria, the need for new drug discovery is pressing and was the goal of this experiment. Soil samples extracted from an ancient Roman City in Pollentia, Spain were isolated and tested for antibacterial and antifungal properties using <i>Pythium</i> and bacterial assays. Isolates that exhibited these properties were then purified using silica gel flash chromatography and PowerSoil DNA extraction was used to help identify the bacterial strain. Of eighteen isolates tested, six exhibited antifungal characteristics and one exhibited antibiotic characteristics.
