Decreased sucrose consumption could be due to a high
concentration of sucrose or a deficiency of vitamins, peptides,
or salts. Since sucrose is hydrolyzed to glucose and
fructose, the fructose utilization pathway seems to be
limited11 (fructose accumulation at high dilution rates). The
homofermentative character of the strain for our conditions
is confirmed by the amounts of acetate and ethanol produced
(, 2 g l21). Finally, the maximal specific growth rate
was estimated around 0.3 h21.
