Description
Antibiotic resistance is an increasing concern in public health, which makes finding new antimicrobial sources especially important. Soil is known to contain a wide variety of bacteria, some of which can produce substances that inhibit the growth of other microorganisms. In this study, a soil sample was serially diluted and plated to isolate individual bacterial colonies, which were then transferred to master plates for further testing. These isolates were screened using streak plate methods to observe their effects on indicator bacteria. One isolate, labeled #10, showed a clear zone of inhibition against Enterococcus faecalis, suggesting antimicrobial activity. Overall, these results demonstrate how soil bacteria can play a role in identifying potential new sources of antibiotics.
