Figure 5From: Effects of supplementary butyrate on butanol production and the metabolic switch in Clostridium beijerinckii NCIMB 8052: genome-wide transcriptional analysis with RNA-SeqCalculated undissociated butyric acid (UBA) levels over time in R1 and R2 based on the measured butyrate concentration. The onset of solvent production was indicated by green arrow (for R1) and red arrow (for R2), respectively.Back to article page
