| Lysine | 549.2 ± 33.1 |
| Alanine | 1.1 ± 0.9 |
| Glycine | 15.8 ± 6.6 |
| Dihydroxyacetone | 167.7 ± 25.8 |
| Glycerol | 9.6 ± 3.2 |
| Trehalose | 5.4 ± 1.1 |

Values are means from parallel incubations on 20 mM [1-13CFru]sucrose, 20 mM [1-13CGlc]sucrose, and 20 mM [13C6Fru]sucrose, with corresponding deviations between the three cultivations. All yields are expressed as millimoles of product per mole of sucrose except for the yield for biomass, which is expressed as milligrams of dry biomass per millimole of sucrose.
