QUESTION 2 Match the media with the statement that best describes it.
C. Mannitol Salts Agar (MSA)
Eosin Methylene Blue Agar (EMB)
B MacConkey Agar (MAC)
A. fermentation of sugar in agar produces a yellow color within the agar due to a
change in pH
B. bacteria that metabolize lactose lower the pH of this media (the pH indicator of this
media is called neutral red)
C. is considered to be a differential but not selective media; this agar is actually an
enrichment agar (supports lots of microbes)
D. Rapid lactose fermentation and production of strong acids (lowering pH of
media) are a factor in producing colors within this agar (such as a metallic green
sheen seen with Ecol)
C
O Blood Agar
