Fig. 6From: Growth of the facultative chemolithoautotroph Ralstonia eutropha on organic waste materials: growth characteristics, redox regulation and hydrogenase activityHyd activity of R. eutropha H16 bacterial cell extracts during bacterial growth under different conditions. F—0.05% fructose, M–Ni and Fe ions, BC buffering components. a SH activity on BSGH; b MBH activity on BSGH; c MBH and SH activity after growth in GFN medium. One unit of Hyd activity was defined as the amount of enzyme that catalyzes the conversion of 1 μmol of H2 per min.
