Abstract:
Bacterial cellulose is pure cellulose synthesized by various species of bacteria.
Bacterial cellulose can be applied in the medical field as a substitute for non-halal
gelatine. This study purposed to isolate and produce cellulose-producing bacteria
which can be applied as materials for halal capsules. Isolation of cellulose-producing
bacteria was carried out on palm oil plantation waste and three different tropical fruit
sources (pineapple, and sapodilla) from Riau using Hestrin-Schramm media in static
culture condition. The determination of dry weight and water content was carried out
to know the quality of the cellulose pellicles. In this study, 10 isolates succeeded in
forming a clear zone from pineapple dan sapodilla. The Z/K ratio obtained from AC
was 4,46-5,43 cm and MZ was 4,03-4,58 cm. However after the production test was
carried out, all of these isolates failed to form cellulose pellicles.
