Every test matched with my experimental results except for the fermentation of lactose. According to Appendix E, E.aerogenes is able to ferment lactose however my enterotube experiment yielded a negative result. I assume this difference is due to human error of misidentification of the color of the enterotube chamber. Besides, the MacConkey plate yielded a…

    inhibits the growth of most Gram-positive organisms and can determine if an isolate is a lactose fermenter. If the isolate were a lactose fermenter this would be indicated by a dark color change in the colonies that formed. The EMB test results showed isolate 6B to form a metallic dark blue color, which, indicated isolate 6B was most likely a Gram-negative organism and a lactose fermenter. To ensure isolate 6B was a lactose fermenter, a test on MacConkey agar was performed. MacConkey agar is…
