Induction of transporters on dulcitol. Cells were transferred from autotrophic to heterotrophic conditions with 25 mm dulcitol as substrate (solid line, cell growth). A, Uptake capacities of cells for [¹⁴C]Glc (●), [¹⁴C]Fru (▴), [¹⁴C]mannitol (▵), [¹⁴C]Fuc (○), and [³H]Rha (□) were monitored. B, Uptake of [³H]Rha was monitored during exponential cell growth on dulcitol (solid line, cell growth; □, Rha uptake) and after transfer of cells to Glc (arrow) (broken line, cell growth; ▪, Rha-uptake). Experiments were repeated at least three times. fw, Fresh weight.

Growth of Backusella ‘group X’, B. mclennaniae and B. liffmaniae on media containing either dulcitol or glucose as a sole carbon source.

Sugar fermentation tests using lactose, maltose, fructose, galactose, dulcitol, and starch for (a) 1B and (b) 2D1 strains.
