Growth and H2 production of the wild-type and FO strains in formate-supplemented medium. Growth (a) and H2 concentration (b) of the wild-type (black bars) and FO (gray bars) strains were monitored at the indicated time points. Cell growth was monitored by measuring the optical density at 600 nm (OD600). All experiments were carried out twice independently, each in triplicate
