Isolasi dan Karakteristik Bakteri Pendegradasi Selulosa pada Ampas Tebu Kuning (Bagasse)

Abstract: Cellulose is the main carbohydrate synthesized by plants and it occupies almost 60% of the components of the structure of plants. Natural  process of decomposition of cellulose requires the help of microorganisms that  secrete  the  enzyme  cellulase.  Bagasse  contains  32-34%  cellulose.  This  study  aims  to  determine  the cellulose  degrading bacteria of  yellow bagasse and know the ability  of the bacteria to  degrade cellulose bagasse.  The  samples  were  taken  from  ice-cane  seller  in  the  District  of  South  Pontianak.  To  isolate  of cellulose degrading bacteria, the dilution method of  Carboxymethylcellulose (CMC) was used and HC test was  performed  on  solid  CMC.   Dry  weight  of  test  was  performed  using  a  fresh  bagasse  as  a  source  of cellulose. The results showed that there are fifteen pure isolates of cellulose degrading bacteria  consisting of eight genera, namely  Psedomomas, Bacillus, Nocardia, Kurthia, Vibrio, Flavobacterium, Neissera,  and Micrococcus. AT3BPS2 isolates (Nocardia) has the largest ratio of 2.67 HC. Isolates that have the lowest HC  constellation  is  AT1BPS1  isolates  (Pseudomonas)  1.06.   Isolates  that  has  the  highest  cellulose degradation ability  is AT1BPS2 (Pseudomonas) at 19.28% and isolates with the lowest degradation ability is AT3BPS2 (Nocardia) at 7.21%.
