Abstract: | Summary Using a pulsed gas and liquid flow and with cells directly adsorbed on to a suitably-formed support, aerobic transformations can be carried out in a fixed-cell reactor with significant gain in efficiency. Immobilized cells of Acetobacter on cordierite can produce acetic acid at a high rate which, at different dilution rates, may be limited either by product inhibition or by oxygen transfer requirements. |
