Improvements to the Kinetoscope allowed it to hold more

learned so far in the microbiology laboratory class for the identification of unknown bacteria. The identification process can be completed with a series of deferential stains and biochemical tests. Creating a dichotomous key helps to limit the amount of biochemical tests done on an unknown organism and by observation and recording of data the unknown organism can be found. Materials and Methods The procedure for all tests performed was taken from Leboffe and Pierce’s Microbiology: Laboratory Theory
