Description

DESCRIPTION

MALT EXTRACT is prepared by successive purifications, removing all enzymatic activity. In solution, it has a very light colour. It is particularly well suited for culturing yeasts and moulds, allowing the sporulation of moulds such as Aspergillus and Penicillium. It has high carbohydrate content and should not be heated in excess to avoid the darkening of the medium. Malt Extract provides carbon, protein and nutrients in culture media.
