Figure 2From: Genome-wide transcriptional analysis suggests hydrogenase- and nitrogenase-mediated hydrogen production in Clostridium butyricum CWBI 1009 Volcano plot distribution of Clostridium butyricum CWBI 1009 mRNA transcript levels (RNA-seq) during unregulated-pH glucose fermentation. The colour code corresponds to the expression level and is presented as an RPKM value for pHÂ 6.3. Dots corresponding to the hydA2, hydA8, hydB2, hydB3 and nifH genes are indicated.Back to article page
