The proportion of synthesized 13C-compounds detected by NMR at the time of 50% glucose consumption
Temperature (°C) | Time (days) | Glycerol % (SE)*,† | Phospholipids % (SE)*,‡ | Polymeric carbohydrates % (SE)* | Proteins % (SE)* | Ethanol % (SE)* | Total %¶ | 13C (SE)§ {from[13C]CO2) |
9 | 2.5 | 11 (0.003) | 16 (0.009) | 63 (< 0.001) | 4 (0.007) | 3 (< 0.001) | 97 | 1.57 (0.75) |

SEs are estimated.
*Percent of the total synthesized 13C-compounds at the time when 50% of the added glucose was left.
†Corresponds to C1 and C3 in glycerol.
‡Corresponds to the acyl chain of phospholipids. The synthesized 13C-compounds at the time when 50% of the added glucose was left could not be estimated at −9 °C.
¶Total % of the interpolated fractions of synthesized 13C-compounds at the time when 50% of the added glucose was left.
