Table 3 Consumed glucose concentration, consumed glycerol concentration, PDO concentration produced, and yield on glycerol of PDO

From: 1,3-propanediol production with Citrobacter werkmanii DSM17579: effect of a dhaD knock-out

  Aerobic condition Anaerobic condition
  Glycerol Glycerol + glucose Glycerol Glycerol + glucose
Glucose consumed (mM) NA 55.2 ± 0.3 NA 45.0 ± 0.1
Glycerol consumed (mM) 136.9 ± 2.7 5.9 ± 0.3 54.7 ± 3.5 132.5 ± 0.2
PDO produced (mM) 14.0 ± 0.5 2.4 ± 0.1 97.6 ± 1.9 94.9 ± 2.9
Yield (mol PDO/mol glycerol) 0.1 ± 0.0 0.4 ± 0.0 0.6 ± 0.0 0.7 ± 0.0
  1. C. werkmanii DSM17579 was grown under (an)aerobic conditions in media with 163 mM glycerol only or 54 mM glucose and 163 mM glycerol (0.33 molar ratio) as carbon sources. (NA = not applicable).
