Fig. 1From: Impairment of NADH dehydrogenase and regulation of anaerobic metabolism by the small RNA RyhB and NadE for improved biohydrogen production in Enterobacter aerogenes Diagram of primary anaerobic metabolic pathways for bacterial hydrogen production. Shown are three putative strategies to enhance hydrogen yield as outlined in this study. The diagram was adapted from references [8], [17], and [18]Back to article page
