A new type of continuous fermentor has been developed which features an agitation‐aeration system based on pulsed flow across perforated plates the use of plug flow to achieve a concentration gradient. The influence of the agitation‐aeration parameters (in this case the pulsed speed) has been measured, and mathematical models have been produced for the gas hold‐up, the power dissipated in agitation and aeration, the oxygen‐transfer rate, and efficiency. The oxygen transfer is high, up to 600 mmol/liter hr with a transfer efficiency much higher than that published for any other technique.
