This experiment showed that S. marcescens has motility. When this bacterium used up all of the recourses at the point of inoculation, it was able to move towards the side of the Petri dish with more nutrients. This organism was unable to grow sufficiently enough on the water agar to move towards the GYE. The tests with E. faecalis did not provide definitive evidence that this organism is non-motile. This organism did not grow well on either media, and its ability to move could not be observed. Using a different media could allow for the motility of E. faecalis to be observed more clearly. In conclusion, this chemotaxis experiment provided evidence of motility in S. marcescens, but was inconclusive in determining the motility of E. faecalis.
