*The metabolic potential was assessed by API 50CH. **Values represent the number of metabolized sugars out of forty-nine tested. D-raffinose and inulin catabolism is presented as the number of strains capable of utilizing these compounds. *** Growth promotion by prebiotics was assessed by measuring cell density (OD600nm) in liquid culture; (−), no growth stimulation (growth as in standard medium without added sugar); (+), weaker growth than on standard medium with added sugar; (++), same growth as on standard medium with added sugar; (+++), better growth than on standard medium with added sugar. The number of strains meeting the given criteria is given in brackets.
