Carbohydrate fermentation profile of S. pneumoniae strains.

*strains are described in reference [32];**Carbohydrates are grouped according to the structure in monosaccharides, alpha-glucosides, beta-glucosides, alpha-galactosides, beta-galactoside, polysaccharides. Intensity of fermentation, detected as the degree of colour change of a pH indicator, is given in arbitrary units from 1 (no fermentation) to 5 (excellent fermentation).
