A Chronoamperometric curves of three-electrode systems inoculated with strain Lsc-8 with CMC as the carbon source at different constant potentials; the inset shows chronoamperometric curves of three-electrode systems inoculated with strain Lsc-8 with CMC as the carbon source at a constant potential of 0.35 V; arrows indicate the replacement of half of the solution in the reactor with new CMC medium. B Chronoamperometric curves of three-electrode systems inoculated with strain Lsc-8 with medium I as the carbon source at a constant potential of 0.35 V
