โœฆ Synopsis

The capability of the continuous tower fermenter to accumulate and retain high cell densities (70-90 g dry wt/l) when using naturally flocculant yeasts is demonstrated with semi-defined glucose feed at concentrations of 120-200 g/l and high hydraulic loadings. Conversion and ethanol productivity data are given as a function of throughput and feed glucose concentration.

Flocculation was induced in a pure strain of the bacteria Zymomonas mobili~. When fermenting glucose to ethanol, cell densities of up to 40g/l were achieved and sustain@d in a 0.92 litre tower fermenter with dilution rates of up to 2.3 hr-'. A maximum productivity of lOOg EtOH/I/ hr with 98% conve
