Description
Due to the over/misuse of common antibiotics, bacteria have been changing and developing resistance to many antibiotics. This makes these resistant bacteria very dangerous for humans who are infected by them. Currently, the most concerning antibiotic resistant strains of bacteria are known collectively as E.S.K.A.P.E pathogens. Many people are trying to find new and effective antibiotics that can inhibit the growth of these pathogens. A group called the Tiny Earth Project uses research that students collect to find a new effective bacterial species which inhibit the growth of one or more E.S.K.A.P.E relatives. The research I conducted in the lab started by collecting a personal soil sample from a location of my choosing. I chose a spot near the walking path by my backyard due to the plant life and convenience of the location. This sample was then diluted and plated to find any bacterial colonies that showed signs of inhibition. Of these colonies that I collected none of the candidates I had from my own soil proved to have effective zones of inhibition against E.S.K.A.P.E. relatives. This suggests that my soil sample was not a rich source of antibiotic producing bacteria. I ended up choosing a candidate that I isolated from the communal lab soil dilution, and I used this candidate for further testing.
