The synthetic fruit medium
that consisted of the nitrogen sources in HS medium and sugar
reagent (glucose, fructose and sucrose) was also used for bacterial
cellulose production (medium II). Sugar concentration in each
experiment was decided based on the sugar content originally
present in the fruit juices. The fruit juices, whose pH was adjusted
to 6 was used as medium III. The bacterium was grown in the medium
I–III at 30 C.
