Table 2 Specific enzyme activity of GDH in C. werkmanii DSM17579 (WT) and C. werkmanii DSM17579 ∆ dhaD (KO)

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
WT (U/mg) 1.406 ± 0.283 0.005 ± 0.002 3.770 ± 0.259 1.293 ± 0.214
KO (U/mg) 0.007 ± 0.003 BDL No growth 0.022 ± 0.005
  1. Both strains were grown under (an)aerobic conditions in media with 163 mM glycerol only or 54 mM glucose and 163 mM glycerol (0.33 molar ratio glucose/glycerol) as carbon sources; BDL = below the detection limit.
