Beschreibung
Zusammenfassung:	Un método para purificar un polisacárido capsular a partir del Estreptococo agalactiae que se compone de una fase de filtración en la que se utiliza un filtro adherente, donde el método no incluye una fase de tratamiento con detergente catiónico para precipitar el polisacárido capsular, seguida de una fase de resolubilización del polisacárido capsular. This invention is in the field of bacterial cultures, and specifically relates to the optimization of culture conditions to improve the production of bacterial capsular polysaccharides from Streptococcus strains in fed batch culture and to novel purification methods suitable for production scale purification of bacterial capsular polysaccharides from Streptococcus strains resulting in higher levels of purity than previously obtained for production scale.
