Tomato Juice Broth: Principle and Composition

Tomato Juice Broth

Tomato juice broth used in Lactobacilli culture media was first described by Mickle and Breed. Kulp noted the ability of tomato juice to improve the recovery of Lactobacilli which is now recommended for yeast and other aciduric microorganism’s culture.

Principle of Tomato Juice Broth

  • Tomato juice is a source of carbon, nutrients and proteins.
  • Yeast extract offers nitrogenous compounds and amino acids that boost the development of spoilage strains.
  • Low pH of the medium promotes the development or growth of lactobacilli while inhibiting that of associated bacteria.
  • The medium is buffered with phosphates.
  • Sulfate of magnesium, sulphate of manganese and ferrous sulphate provide inorganic ions.
  • Sodium chloride retains the osmotic balance of the medium.
