far in the microbiology laboratory class for the identification of an unknown bacterium. Hypothesis By slowly narrowing down the bacteria by each test‚ I will be able to conclude the unknown bacteria by its special characteristics. MATERIALS AND METHODS An unknown labeled as #54 was given out by the lab instructor. The methods that have been learned thus far for identifying bacteria have been applied to this unknown. Procedures were followed as stated in the course laboratory manual‚ unless
