Polyol utilization test by GBS-S19 using tryptone water. Polyols or glucose (a) 1%, (b) 2% and (C) 4% were added to 10 ml of tryptone water with phenol red and inoculated with GBS-S19. Tryptone water without GBS-S19 inoculation was used as a negative control (Blank). Glucose was used as a positive control and showed acid production (yellow color). Glu. (glucose), Ery.
