摘要

Manufacture of a foodstuff or a biotechnological product, by fermentation in a medium (in which a control of redox potential of the medium is essential), comprises regulating a predetermined setpoint level of the redox potential of the medium by controlled addition of treatment gas to the medium and permitting the process to pass to the next level when the setpoint is reached.
