1. Claims (for the Contracting States : BE, CH, DE, FR, GB, IT, LI, LU, NL, SE) Process for the production of immunogenic capsular polyosides from capsulated bacteriae containing same, characterised in that it consists in cultivating the bacteriae in a synthetic medium which may contain up to about 0.5% by weight of naturally occuring materials ; at the end of the growth stage of said culture removing the microbial bodies, submitting the liquid phase after removal of the microbial bodies to a filtration through a membrane which retains the molecules of a molecular weight of 100 000 daltons or more, to give a capsular polyosides-rich retained material ; and removing the proteins, the nucleic acids and the lipids from said retained material, to give a purified capsular polyoside. 1.
