Culture systems involving the use of one or two fermenters in series,
with cell recycle employing hollow fiber filter modules to achieve hig
h cell densities, were developed. Dilution rates of about 0.6 h(-1) an
d ethanol productivity values of about 25 g/l h(-1), with residual glu
cose at 0.9 g/l, could be achieved using the system employing one ferm
enter.
