- Abstract
Coffee pulp waste contains 25.9–33.0% hemicellulose. Hemicellulolytic bacteria possess the ability to depolymerize hemicellulose by producing hemicellulase enzymes. The objective of the research is to isolate and identify the hemicellulolytic bacteria from Indonesian coffee pulp waste. Hemicellulolytic bacteria were isolated from coffee pulp wastes of Coffea arabica and C. canephora from two coffee plantations in East Java Province, Indonesia. These isolates were selected based on the hydrolysis of xylan and xylanase activity on the xylan medium. The best isolates were identified based on 16S rDNA sequence similarity. In this research, 23 bacteria had isolated. Five isolates XRM21, XAJ25, XAJ30, XAJ31, and XAJ34 had higher hemicellulolytic activity than others. The XAJ25, XAJ31, and XAJ34 isolates had a good xylanase activity performance. The XAJ34 isolate had the highest xylanase activity (3.38 ± 0.65 U/ml). The XAJ34 isolate based on 16S rDNA sequence similarity was identified as Bacillus aureus. This bacterium is considered a potential indigenous isolate to degrade hemicellulose of coffee pulp waste.
