Beschreibung
Zusammenfassung:The invention belongs to the technical field of amino acid fermentation, and discloses a method for preparing sodium glutamate through concentrating continuous freezing isoelectric point crystallization. The method comprises the following steps: 1) preparing a corynebacterium glutamicum seed solution; 2) preparing a brevibacterium lactofermentum seed solution; 3) mixing and stirring; 4) preparing sodium glutamate through fermentation; 5) implementing concentrating continuous freezing isoelectric point crystallization; and 6) processing waste liquid. The method disclosed by the invention is high in fermentation efficiency, low in industrial energy consumption and is energy-saving and emission-reducing.
