Finding Antibiotics in Soil

For this project, my objective was to explore the potential of soil-derived solutions in identifying novel antibiotics. To achieve this, I utilized soil samples, isolating them into different bacterial colonies. By diluting the samples and isolating individual colonies, I was able to conduct targeted tests. Each colony was exposed to specific antibiotics, and the resulting bacterial growth was monitored for a zone of inhibition. During my investigation, I discovered that one particular strain of bacteria, identified as the sixth colony, exhibited a significant zone of inhibition when exposed to Enterococcus faecalis. This finding suggests that this particular bacterium may harbor antimicrobial properties, showing promise as a potential candidate for further development as a therapeutic agent. This research highlights the importance of exploring unconventional sources, such as soil, to discover new antibiotics that may help address the increasing challenge of antibiotic resistance and enhance our ability to treat infectious diseases.
