1. Co-Principal Investigators:Wesley Crow Logan Burks Cole Klinkhammer Samuel Sheahan THE EFFECT OF MICROGRAVITY ON BACTERIAL GROWTH AND ITS RESISTANCE TO ANTIBIOTICS.

2. THE EXPERIMENT The Effect of Microgravity on Bacterial Growth and its Resistance to Antibiotics. The Question: Will bacteria be less susceptible to antibiotics after it is grown under the influences of microgravity? Previous Results Other experiments conducted. Our Pretest results Our Hypothesis

3. MATERIALS & PROCEDURE Antibiotics used: Penicillin, erythromycin, and vancomycin Bacteria used: staphylococcus epidermidis Why this bacteria? Pre-flight Stages: Activation: Post-flight Experimentation:

4. RESULTS We observed that the zone of inhibition created was smaller for the bacteria grown in space compared to the bacteria grown on earth. We think this phenomenon could be credited to bacteria growing better in microgravity What differences we observed.

6. QUANTITATIVE RESULTS Microgravity Test Results Ground Truth Results

7. CONCLUSION Why is microgravity a more advantageous environment for bacterial growth? Our Hypothesis Future Experimentation Other bacteria Viruses How can this be applied?
