When I first started working in Dr. Jonathan Eisen’s lab my junior year of college, I was assigned a pretty open ended task. Swab something from the built environment and see what grows. This being the first time I was actually doing research, I was incredibly excited to go out and swab the world. My main target, however, was my work place. A place where human sweat, grime, and years of oily hands and skin particles had turned the equipment to a discolored and often black shade. I had seen how often everything was cleaned, and it was not often enough. This sparked my initial question. What kind of bacteria grows in a gym?
After swabbing four pieces of equipment, growing plates, and isolating four interesting–looking cultures, it became clear to me that I had not even begun the real research. It took me at least a month to be able to successfully extract DNA from the samples. I believe that I attempted PCR a total of nine times before it worked enough to go to the next stage. Then the sequencing did not work, so I had to do PCR over again. Dr. David Coil was incredibly patient, even when I was visibly frustrated that I couldn’t get anything right. Step after step took months for me to complete, until finally I got real results. Arthrobacter Sp. strain UCD-GKA was what came out of my trial by fire. Though the phylogenetic tree could not determine exactly what species of Arthrobacter I had found, I am still incredibly proud of it. Though the process was long and arduous, the reward was great, and resulted in a draft genome announcement for the bacteria that I had found on a small weight bench in a gym.
