Cellulase is an enzyme that can hydrolyze the β-1,4 glicosidic of cellulose and produce glucose. Cellulase can be produced by many microorganisms include endophytic bacteria Pseudomonas stutzeri LBKURCC 54 and LBKURCC 59 at fermentation time of 10, 20, 30, 40 and 50 days. The activity of cellulase was determined by the Nelson-Somogyi method. The results showed that highest cellulase activity of LBKURCC 54 was occurred at the 40th day of fermentation time (1.900 ± 0.346) x 10-3 U/mL, while the highest cellulose activity of LBKURCC 59 was occurred at the 30th day of fermentation time (3.530 ± 3.415) x 10-3U/mL.encellulosedisposable diapersendophytic bacteriasolid state fermentationstudent Paper Post Degree
