Abstract:Summary In some fermentations micro-aerobic conditions are desirable. The controlled addition of trace amounts of oxygen may be achieved by bubble free oxygen supply using silicon membrane tube, operated in dead-end mode. The small oxygen uptake rate is accurately determined with this self-constructable device.
