Abstract: Ethanol is one of
fermentation products which are mostly used as solvent in pharmaceutical and chemical
industries. Ethanol production
by fermentation generally
uses yeast from Saccharomyces and
Schizosaccharomyces. The fermentation
of ethanol by
both processes yields great
quantities of ethanol.
Optimum productivity in
ethanol fermentation by continuous
process using Schizosaccharomyces pombe
was obtained at
initial substrate concentration
of 200g/L, with value as much of
7.342g/L·hour at dilution rate of 0.1/hour, 4.643 g/L·hour at dilution rate of
0,06/hour and 3.213g/L·hour at dilution rate of 0.04/hour. The highest
value of ethanol
coefficient YP/S obtained
at initial substrate
concentration of 100g/L was
as much of
0.461 at batch
process, while values
of ethanol coefficient
YP/S obtained were in
the range of
0,477-0,511 in continuous
process, which were
higher than those of batch
process.
