一般描述
Malt extract powder is prepared from an aqueous extract of sprouted malt grains and dried at low temperatures to preserve nutrients. This malt extract is a purified and clarified malt extract, supplemented with growth factors. It is easily soluble in water. It contains a mix of carbohydrates (mainly maltose) and growth factors. It is ideally suitable for use in media employed for cultivation of fungi.
应用
Malt extract powder is added to specific culture media to enhance the nutrient quality of the media. It is most suited to enhance the growth and cultivation of fungi, yeasts, and molds
