  1. aData for 35°C from [26].
  2. bStudied on 14C-BC as a substrate at 35°C.
  3. cAnalyzed using the concentrations of IOS free from cellulose.
  4. dAnalyzed using the total concentrations of IOS.
  5. eStudied on 14C-amorphous cellulose as a substrate at 35°C.
  6. fBecause of the long extrapolation (Figure 7D), this is only an approximate value and must be treated with caution.
