What test purpose is this:
To determine if a microbe can split indole from the amino acid tryptophan
What test is this:
Media = 1% tryptone broth (Not SIM agar like your lab manual says)•
Enzyme = Tryptophanase
•Indicator = Kovac’s reagent
What test is this:
selects for organisms found in the family, Enterobacteriaceae, and differentiates between members of that family that can produce tryptophanase & those that cannot
What test and what are results?
