what type of gram reactions are possible in macConkey and blood agar and why?
Homework Answers
McConkey agar is selective and differential media it selects bacteria based on ability to ferment the lactose. it contains bile salt and crystal violate dye which inhibits the growth of gram-positive bacteria so it only grows gram-negative bacteria.
blood agar is differential media but nonselective. bacteria which able to hemolyze the blood are grown on this media like streptococcus. in blood agar both types of gram positive and gram negative cells are grown.
