Abstract

La presente invenzione riguarda un metodo per controllare la concentrazione della sorgente di carbonio nella coltura erobica di un microrganismo. La sorgente di carbonio di substrato rimane ad un livello basso nel recipiente di coltura durante l'alimentazione della coltura in colture aerobiche ad alimentazione discontinua, continua oppure continua con riciclo di cellule. Ciò viene realizzato controllando l'aumento del pH oppure del contenuto in ossigeno disciolto nel mezzo di coltura e aggiungendo la soluzione di alimentazione a intervalli in un recipiente di coltura in corrispondenza di una portata di alimentazione calcolata impiegando un dispositivo di controllo dell'alimentazione controllato da un computer. La presente invenzione riguarda inoltre un procedimento per produrre L-lisina mediante fermentazione il quale procedimento ha vantaggi rispetto ai metodi precedenti, questi vantaggi essendo una migliorata produttività, maggiori concentrazioni di prodotti accumulato e rese aumentate di L-lisina.
