Day 1

Each lab group was given an unknown sample of bacteria to perform various tests on to determine its identity. We were given sample #5. From the original stock of sample we, by means of aseptic transfer, transferred the bacteria to an Agar Plate, Agar Slant test tube and nutrient broth to culture new bacteria.
