LB Broth MILLER is a granulated medium for the cultivation of E. coli on scales ranging from small cultures to fermentation. The granules ensure rapid and uniform dissolution in water, and prevent clumping of the medium and inhalation of the airborne powder. The composition of the LB Broth MILLER per liter is 5 g yeast extract, 10 g peptone from casein, and 10 g sodium chloride.
