This document is a completed lab report for Principles of Microbiology (BIO 3305) at Kean University, specifically focusing on the identification of an unknown bacterium designated as organism #141. It was submitted by Bianca Benitez on May 10, 2018, to Professor Berkefeld.
This report is valuable for students in similar microbiology courses who need a model example of how to structure and present findings from unknown organism identification experiments. It demonstrates the application of various microbiological tests and the interpretation of results to arrive at a tentative identification. It also serves as a record of experimental procedures and observations for the instructor.
This report does *not* provide instruction on how to perform the tests themselves, nor does it offer a comprehensive guide to bacterial identification. It represents a single student’s work and should not be used as a substitute for understanding the underlying principles and methodologies.
The full report includes an abstract summarizing the identification process, an introduction outlining the importance of microbial identification, a detailed materials and methods section describing the experimental procedures (including Gram staining, catalase, nitrate, and fermentation tests), and a table listing the tests performed and their reagents. It also contains the results of each test and the student’s conclusion regarding the identity of the unknown organism as *Bacillus megaterium*. This preview does not include the full results table or the detailed descriptions of observations made during each test.
