Fig. 2 shows the flow chart of bacterial cellulose production
process from various component of orange. The orange was divided
by pulp and peel, and the amount of pulp and peel provided
from 100 g of orange were 83.9 g and 16.1 g,
respectively. The pulp was squeezed, and then divided into fruit
juice and squeeze residue. The medium consisting of fruit juice
adjusted pH 6 and nitrogen source in HS medium was prepared,
and the bacterial cellulose of 0.48 g (dry weight) was produced
from the medium. The squeeze residue and peel were saccharized
by Meicelase, the glucose yield were 16.5% and 20.7%,
respectively. The media consisting of the saccharides solutions
adjusted pH 6 and nitrogen source in HS were prepared. And
the amount of bacterial cellulose (dry weight) from the media
using the squeeze residue and peel were 0.04 and 0.13 g, respectively.
It was confirmed that an inhibitor for the bacterial cellulose
production and the cell growth and were not included in
saccharose solution. Thus, the bacterial cellulose of 0.65 g (dry
weight) was produced from the orange of 100 g, and the solid
residue from the orange was about 17.2 g. From the above-mentioned,
the process of the effective utilization of the surplus produced
and dumped orange was suggested
