Explanation:
Detailed explanation-1: -Eosin-methylene blue agar is selective for gram-negative bacteria against gram-positive bacteria.
Detailed explanation-2: -Some gram-positive bacteria, such as enterococci, staphylococci, and yeast will grow on this medium and usually form pinpoint colonies. Non-pathogenic, non-lactose-fermenting organisms will also grow on this medium.
Detailed explanation-3: -Principle. Eosin Methylene Blue agar (EMB agar) is both selective and differential culture medium ideally used for isolating faecal coliforms. It is a selective medium due to inhibition of gram-positive bacteria by methylene blue.
