Table 1 Overview of fermentations 1–5

From: Promoting the co-utilisation of glucose and xylose in lignocellulosic ethanol fermentations using a data-driven feed-back controller

Fermentation Mode Initial volume (L) Volume fermented (L) Inoculum (g) Time (h) Ethanol productivity (g/L/h) Ethanol production rate (g/h)
1 Fed-batch 1.00 1.81 1.75 19 1.13 1.94
2 Fed-batch 1.00 1.86 1.75 20 1.08 1.99
3 Fed-batch 1.00 1.86 1.75 22 1.02 1.90
4 Fed-batch 1.00 1.95 1.75 19 1.13 2.21
5 Batch 1.24 1.24 1.75 25 0.85 1.05
  1. Productivities and production rates refer to ethanol formation. The fermented volume was calculated from the mass of media added in each fermentation, considering a density of 1.05 g/L. The ethanol productivity and production rate were calculated when the concentration of xylose dropped below 0.5 g/L
