Eоsin-methylene blue аgаr (EMB) is а cоmmоnly 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.

If an organism consumes lactose, acid will be produced, causing the bacterial colonies to change color. Based upon this description, this medium is
