make a dichotomous key
Study Bring Lab Practical Study NNNN CHALLENGE QUESTION You are given an unknown bacterium to identify. You do some initial testing and determine that the bacterium is a Gram-negative, motile rod with no unique colony morphology or pigmentation when grown on an agar plate. Given the following metabolic profiles for six known Gram-negative rods. create a dichotomous key which will guide the testing of your unknown bacterium. List all of the tests that you will need...

Background
Ques part 1)
Selective and differential media; EMB and Tsl agar bacill inhabit a wide range of environments. Many are significant pathogens, such a coli, Salmonella, Shigella, but many compose our normal flora and inhabit soil and water. Many gra negative bacilli that inhabit our large intestine are called enterics. Enteric pathogens are the most frequent cause of diarrheal illnesses and have become significant contaminants spread through foo Some can also cause respiratory and urinary infections. Experiment 1: EMB...
