    ISOLASI BAKTERI PENGHASIL SELULOSA DARI TANAH MANGROVE DAN BUAH-BUAHAN TROPIS SEBAGAI BIOMATERIAL UNTUK PRODUKSI KERTAS
    (2020-10) Sinaga, Lukcya; Zul, Delita
    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.
