Malt extract is made from aqueous extraction of malt. This extract dried at low temperature that retains carbohydrates.
Carbohydrates include maltose, glucose, fructose, sucrose, and others are rich in malt extract. Vitamins, free amino acids, and short peptide fragments are examples of nitrogenous substances.
Bacteria may directly use free amino acids, which are easily obtainable, to build proteins. Short Peptide Fragments can also be used by some bacteria as a nitrogen source.
Malt extract is beneficial for sporulation of molds like penicillium and aspergillus.
