Abbreviations: NI = end-product not investigated; ND = end-product investigated, but not detected; NQ = end-product detected, but not quantified; NC = end-product quantified, but ratio not calculable due to missing substrate consumption data; B = batch culture; P = pH-controlled batch culture.
1
T. ethanolicus CCSD1 omitted as no physiological data is available.
2
End product and substrate utilization data used for calculations approximated from graphical data.
3
Succinate production reported as a minor product.
