Figure 2From: Effects of supplementary butyrate on butanol production and the metabolic switch in Clostridium beijerinckii NCIMB 8052: genome-wide transcriptional analysis with RNA-SeqSolvent and acid production over time with the onset of solvent production indicated by arrows. (A) Reactor R1: 40Â mM sodium butyrate was added to the growth medium. (B) Reactor R2: no sodium butyrate was added to the growth medium.Back to article page
