Fig. 5From: Impairment of NADH dehydrogenase and regulation of anaerobic metabolism by the small RNA RyhB and NadE for improved biohydrogen production in Enterobacter aerogenes The hydrogen production from glucose compared by IAM1183 among all strains in serum bottle batch assays (n = 3). The yield of H2 generated through the formate pathway can be calculated by the following equation V h  = V e  + V a  − V f , where V h is the amount of hydrogen produced through the formate pathway, V e is the amount of ethanol, V a is the amount of acetate, and V f is the amount of formate. a Hydrogen evolved from IAM1183-CD and IAM1183-CDE. b Hydrogen evolved from IAM1183/R, IAM1183-CD/R, and IAM1183-CDE/R. c Hydrogen evolved from IAM1183/N, IAM1183-CD/N, and IAM1183-CDE/N. d Special illustration of hydrogen evolved via the NADH pathwayBack to article page
