If the result of an unknown bacteria is “poor growth” and “red growth,” can this result be interpreted as “organism does not ferment mannitol?” Explain why or why not.
If the result of an unknown bacteria is “good growth” and “yellow growth,” is the unknown bacteria more likely Staphylococcus aureus or Staphylococcus epidermidis?
A bacterial organism is used to inoculate mannitol broth medium. Following incubation the broth is yellow. This indicates that the organism:
A) can use lactose and glucose
B) cannot use lactose
C) can use mannitol
D) cannot use mannitol
In the Mannitol Salt Agar, why is there no observed growth of Escherichia coli?
