| Abstract: | Little change in glucose uptake by Fibrobacter succinogenes S85 was observed when the extracellular pH was between 8.0 and 6.5, but uptake was reduced 42 and 65% at pH values of 5.0 and 4.0, respectively. p -Coumaric acid and vanillin were the strongest inhibitors of glucose uptake by F. succinogenes S85, while ferulic acid was less inhibitory. Collectively, these results help to explain, in part, the growth inhibition observed when F. succinogenes S85 is exposed to low extracellular pH and phenolic monomers. |
