HPr His15Asp mutation enables arabinose utilization in the presence of glucose. The level of glucose (triangles) and arabinose (squares) remaining in the culture medium was determined for cultures of T. saccharolyticum strains M2476 (HPr, filled symbols) and M2907 (HPr His15Asp, open symbols) supplemented with (A) arabinose or (B) arabinose and glucose.
