Table 3 Resistance of the microorganisms studied to inhibitors present in feedstock hydrolysates

From: Microbial production host selection for converting second-generation feedstocks into bioproducts

Production host Furfural HMF Acetate NaCl MgSO4 Growth at pH4
E. coli 1 2 5 40 80 -
C. glutamicum 0.5 2 10 40 > 80 -
S. cerevisiae Bioscreen* 1 1 5 20 > 80 +/-
S. cerevisiae Micro-Oxymax* n.d. 1 n.d. 20 n.d. n.d.
P. stipitis 1 2 5 40 > 80 +/-
T. reesei 1 5 20 100 > 80 +
A. niger 1 5 20 100 > 80 +
  1. The concentration (g/l) of the inhibitor is shown at which inhibition results in <50% of the growth rate/CO2 production rate without inhibitor.
  2. *In order to check correlation of the methods, S. cerevisiae was evaluated using both the Bioscreen and Micro-Oxymax method (see Methods).
  3. n.d. = not determined
  4. + good growth
  5. +/- moderate growth
  6. - no or very slow growth
