Do We Have Lazy Bacteria?

On September 22nd Hannah and I went into lab to check on all of the tests that we prepared the last class. Our streak plate showed a lot of growth in sort of round, flower shapes as Hannah described them. The motility tests showed that our unknown bacteria is motile or has the ability to move because there was a "cloud" of bacterial growth around the area where we stuck the needle. Meanwhile, the bacteria from the dollar bill does not move shown by no "cloud" or growth. Because our unknown is motile, we needed to make a hanging drop slide so we can actually see them swim. This is what the broth was for. What we didn't know was that our broth didn't grow enough bacteria to even do a hanging drop let alone see any bacteria. So we tried and failed somewhere around five or six times. Even Dr. Pathakamuri tried and he couldn't see them. Hannah and I joked about having lazy bacteria while our professor searched for what our unknown sample was and to see if it was truly motile. We ended the day with making a new broth that needed to be checked the next day.
