- Purpose Solve the identity of an unknown bacterial specimen by creating a dichotomous key and using the staining, culturing and biochemical identification procedures you have learned about during the semester. Possible Organisms Alcaligenes faecalis Enterobacter aerogenes Enterococcus faecalis Escherichia coli Proteus vulgaris Pseudomonas aeruginosa Salmonella arizoniae Staphylococcus aureus Staphylococcus epidermidis Staphylococcus saprophyticus Streptococcusbovis Streptococcus pyogenes You must write up your OWN dichotomous key for all the possible unknown organisms listed on above. Writing this key requires you use the same type of reasoning used in the Dichotomous key lab. The first step of the key will be the Gram Stain. Subsequent steps will include biochemical tests only.
