Abstract:
The present invention provides an improved method of producing a capsular polysaccharide having a pneumococcal serotype. The method according to the present invention includes a step of additionally culturing bacterial cells producing a pneumococcal serotype without pH adjustment, thereby removing a protein precipitation process by acidification with a pH adjuster.
