The S. pneumoniae serotype 14 capsule can be produced in E. coli.
(a) Western blot analysis of CPS14 expressed in E. coli strains CLM37 (wecA-; waaL+) and CLM24 (wecA+; waaL-) show the production of the pneumococcal capsule in whole cell lysates, LPS extractions and isolated OMVs. (b) TEM of isolated pneumococcal geOMVs.
