Microbiology Lab

Unknown Final report 1. knowledgeability: The purpose of this lab was to blank space two unfathomable bacteria cultures using various derived function bear witnesss.   The identification of these foreigner cultures was accomplished by separating and differentiating realizable bacteria based on specialized biochemical characteristics.   Whether the trial runs performed place specific enzymatic reactions or metabolic path bureaus, each was character in a way to help recognize those specifics and see the incomprehensible cultures.   The differential probes utilize to identify the unknown cultures were oxidase, catalase, lactose and saccharose fermentation, nitrate reduction, jelly hydrolysis, starch hydrolysis, manitol salt, MR-VP, citrate, indole, urease, DNase, and coagulase.   The tests performed on the unknown bacteria cultures were all use to determine the identity of the bacteria.   each(prenominal) of the tests performed provided most key information about the bacteria in head word and how it functions.   entirely of the tests were performed on every culture, however, as some of the tests were used yet for gm (+) or gram (-) bacteria, while others were nevertheless more than specific and identified simply for cocci bacteria.   The tests performed and what constitutes a authoritative and proscribe test be as follows. 2.

It is important that the test is read by unmatched minute to ensure high-fidelity results (avoid trumped-up(prenominal) negatives and false positives).  Unknown 12 resulted in a negative test with no discolor change. These were similar results seen in Eschericia coli, genus Proteus vulgaris, genus Serratia marcescens, and Enterobacter aerogenes.
