The emergence of multidrug resistant bacteria requires new antibiotics to be continually be developed. The actinobacteria are an order of bacteria that have been well documented as antibiotic producers in response to competition mediated environmental stress. This study uses mixed cultures of the actinobacterium Streptomyces griseus and a number of unknown bacteria isolated from pitcher plants in DuPont Forest to screen for antibiotic production. Biological assays were employed to test for the inhibition of Staphylococcus aureus and Escherichia coli growth around the bacterial mixed cultures and each individual unknown bacterium. Work is still being done to find the optimal medium to perform the antibiotic screening assays on. A few bacterial cultures appear to inhibit the growth of S. aureus and E. coli, and the isolation and molecular structure of these antibiotic molecules are still being investigated.
