Discovery Of A Novel Inhibitory Compound Produced By The Soil Bacterium Rhodococcus Sp. Mtm3w5.2, Patrick South
Discovery Of A Novel Inhibitory Compound Produced By The Soil Bacterium Rhodococcus Sp. Mtm3w5.2, Patrick South
Undergraduate Honors Theses
Due to increases in antibiotic resistance stemming from the overuse of commercial antibiotics, the need to discover novel antibacterial compounds is becoming more urgent. A species of Rhodococcus, MTM3W5.2, has been discovered and was found to produce a metabolite with inhibitory activity against closely related species. The aim of this study is to elucidate the structure of the inhibitory metabolite by isolating and purifying it; then characterizing it using spectroscopic techniques. The compound was isolated from MTM3W5.2 RM broth cultures using n-butanol extraction, which yielded an active crude extract. The crude extract was then subjected to fractionation using a Sephedex …

Graduate Student Theses, Dissertations, & Professional Papers
Staphylococcus aureus is a Gram-positive bacterial pathogen responsible for nosocomial and community-acquired infections that can quickly acquire antibiotic resistance. We have identified a novel triazole antimicrobial 31G12 based on the natural product core of nonactin isolated from the fermentation of Streptomyces griseus, that is active against many Gram-positive bacteria as well as antibiotic resistant methicillin-resistant S. aureus and vancomycin-resistant Enterococcus. The synthesis and characterization indicate that 31G12 exists as a mixture of two rotamers at room temperature and displays bacteriostatic activity against S. aureus with moderate mammalian cell toxicity. We have currently identified potential protein targets of 31G12 in …
