. The ability of
Acetobacter to metabolise di¡erent carbon compounds is
due to the fact that many of them are metabolically
coupled with the pentose or citric acid pathway [36,43].
Acetobacter is able to utilise both glucose and fructose
because of an appropriate system for the uptake of these
two sugars. The phosphoenolpyruvate (PEP)-dependent
PTS was ¢rst reported to be absent in a strain of A. xylinus
coherent with the ¢ndings by other workers that this
system has no role in the transport of sugar in strictly
aerobic organisms. Glucose and fructose utilisation for
this particular A. xylinus strain involved the exclusive
phosphorylation of glucose by a constitutive adenosine
triphosphate (ATP)-dependent glucokinase, and of fructose
by phosphorylation by an inducible ATP-dependent
fructokinase, respectively [45,46]. More recently, PEP-dependent
PTSFruc has been described for A. xylinum BPR
2001 [47]. Until now, a speci¢c lactose transport system
has not been reported for the genus Acetobacter. Sucrose
is the main carbon source of the wild-type strain and
again, a sucrose transport mechanism has not been elucidated
in any Acetobacter species published so far. As
PTSSuc [48,49] and PTSLac [50^52] have been described
for other genera of bacteria, then there is a possibility
