T. pseudethanolicus furan aldehyde reduction. T. pseudethanolicus was grown at 65°C with 40 mM glucose and 15 mM (A) furfural or (B) 5-HMF. Growth was measured by optical density at 600 nm. Furan aldehyde concentration was measured spectrophotometrically, while furan alcohol concentration was measured by gas chromatography-mass spectrometry. Error bars are the standard deviation of three replicate cultures.
