Abstract

This research aimed to screen and identifies cellulolytic bacteria from Alas Purwo National Park. Soil samples were taken from five points in each location by indirect sampling method. Bacteria were isolated with CMC (Carboxymethylcellulose) agar. The result had successfully obtained 16 isolates which produced cellulase. The cellulase activity index assay of bacteria used CMC agar modified with adds 1 % YME (Yeast Malt Extract) and then was incubated during one day at room temperature. Bacterial colonies were soaked with Congo red 1 % and rinsed with NaOH 10 % to visualize the halo zone formed. Three isolates with highest cellulase activity index were identified by observing the colony morphology, cell morphology, and the biochemical characters. The results of this research showed that the three highest potential isolates producing cellulase were BPA-B, BSA-D, and BPA-A with cellulase activity indexes respectively 10.67, 9.86, and 8.16. BPA-B, BSA-D, and BPA-A each have the similarity with genera Pimelobacter, Micrococcus, and Cellulomonas.
