The captions and legends for Figures 6 and 7 were incorrectly switched. Please view Figure 6 with its correct caption and legend here:
Figure 6. Vanillin degradation by the constructed consortium and metabolites identification by GC/MS.
Control was the sample without inoculation; Treated was the sample with inoculation.
Please view Figure 7 with its correct caption and legend here:
Figure 7. Semi-batch black liquor treatment by the constructed consortium.
Symbols: for pH (○); Color removal (▵); COD reduction (▴) and Feed volume (•).
Because of this error, in the fifth paragraph of the Discussion section, the last figure citation should be to Figure 6.
