Table 3 Parameter profiles in reactions with ES08 and ES08ΔptsG at pH 5.7 culture conditions

From: Impact of an energy-conserving strategy on succinate production under weak acidic and anaerobic conditions in Enterobacter aerogenes

Strain Biomassa, g[DCW]/L Consumed glucose, g/L End-product, g/L Succinate yieldb, % (g/g) Volumetric productivityc (g/L/h)
Pyruvate Lactate Malate Succinate Formate Acetate
ES08d 7.2 62.9 1.0 0.6 0.3 37.8 0.1 1.0 60.1 0.63
ES08ΔptsG 7.3 63.8 <0.1 <0.1 0.1 55.4 0.1 1.8 86.8 0.92
  1. aInitial biomass was adjusted to ~7.0 g[DCW]/L.
  2. bSuccinate yield is grams of product per grams of consumed glucose expressed as a percentage.
  3. cVolumetric productivity indicates succinate titer (g/L) per hour (h).
  4. dES08 and ES08ΔptsG strains were cultivated for 60 h.
