Q
What is EMB agar?
A
EMB agar is a differential and selective media which is mainly used to identify gram-negative bacteria that can utilise lactose.
2
Q
What is the basis of EMB agar?
A
The basis of EMB agar is that the use of eosin and methylene blue inhibits the growth of gram-positive bacteria whilst also acting as pH indicators so when lactose is fermented by gram-negative bacteria, the media changes to a green or purple colour.
