摘要

A fermentation method and apparatus wherein fermentation medium is continuously circulated between a high pressure region where air and/or oxygen is absorbed and a low pressure region where carbon dioxide is desorbed. The apparatus comprises two connected compartments. During operation differing aeration of the medium in the two compartments produces differing hydrostatic pressures at the lower ends thereof and causes the medium to circulate. The velocity of circulation can be controlled by varying the supply of air to one compartment.
