Profile of carbohydrate utilization by B. longum A10C throughout the growth curve. (A) B. longum A10C growth curve. Cells were cultivated in modified Garches medium supplemented with glucose (diamonds), fructose (squares), or an equimolar mix of the two hexoses (triangles) for the indicated times. (B) Amounts of nonfermented sugars, as measured by HPAEC-PAD. Black bars, d-glucose; gray bars, d-fructose; checked bars, d-glucose in mixed GF medium; hatched bars, d-fructose in mixed GF medium.
