The present invention is a medium for producing capsular polysaccharide from Streptococcus sp., Particularly Streptococcus pneumoniae , which produces capsular polysaccharide, a method for producing the capsular polysaccharide from pneumococci, and a method for purifying the same. In the present invention, by increasing the productivity of the capsular polysaccharide, and by simplifying the separation and purification of the produced capsular polysaccharide, it is possible to economically produce the capsular polysaccharide in high yield. Capsular polysaccharide produced according to the present invention can be used directly or as a carrier (carrier) as a raw material for vaccine production. |
