Abstract:
Bacterial cellulose is a biopolymer produced by acetic acid bacteria through oxidative
fermentation. Bacterial cellulose is used in various industrial fields, especially paper
production due to its excellent physical-chemical properties. This study aimed to isolate
potential bacteria producing cellulose from mangrove soil in Riau and tropical fruits
(rambutan, matoa, apple) to be used as biomaterials for paper production. Bacterial
isolation was carried out on Hestrin Schramm (HS) medium and the production stage
was carried out on HS production medium and modified production medium. There
were 6 potential bacteria producing cellulose isolates; however, none of the isolate
cultures were able to produce cellulose pellicle. The isolate cultures only produced a
thin cellulose mats floating on the medium. The isolate cultures producing cellulose
mats were obtained from apple 1, rambutan 2, 3, and mangrove B2.
