Eosin-methylene blue agar, or EMB, is a differential and selective
commonly used bacteriological medium for
growing gram-negative bacteria from
complex environments. It contains two dyes,
eosin and methylene blue, as well as the
sugar lactose. Eosin is a pH indicator that
changes color when the medium is acidic,
while methylene blue inhibits the growth of
most gram-positive bacteria. If an organism

causing the bacterial colonies to change
color.
