AbstractIon exchange is one of the promising methods for downstream processing in biotechnology. Its advantages are based on selectivity and therefore obtaining of products with reasonable concentration and purity, mild conditions, simple operation and saving of time and energy for product separation. Additional advantage is the possible in situ extraction of ionogenic products from the fermentation broth, including removal of potential inhibitors during the fermentation process.In the case of biotechnology, ion exchange could be considered in two separate ways: ion-exchange solvent extraction and traditional liquid/solid ion exchange by ion-exchange resins. Both approaches have been studied.In this paper, this approach is shown on two important case studies: L(+)-lactic acid and L-lysine recovery from fermentation processes.

Un método de adsorción utilizando la resina Dowex™Marathon™ WBA ha sido desarrollado con el fin de evaluar larecuperación de ácido cítrico producido por fermentación sumergida. Para determinar la viabilidad de este método de separación, la resina fue evaluada a diferentes condiciones de temperatura (30 – 70 °C) y pH (1.5 – 6.5). Los resultadosmostraron que a pH bajo, se mejora la adsorción de ácido cítrico, a través de la cual, se recupera el 85% del ácido y se obtiene una pureza del 92%. Esto representa una capacidad máxima de adsorción de 0.46 g de ácido cítrico por gramo de resina empleada.
