Induction of Agarwood Formation by Lignocellulolytic Bacteria

Agarwood is a hard-textured resin, has scent of fragrant with blackish-brown color, and accumulated on the wood agarwood-producing tree. Gyrinops versteegii (Gilg.) Domke one trees, endemic in Lombok Island, West Nusa Tenggara. The resins were formed as plant response to microbial infection. research aimed investigate activity bacterial isolates able induce resin-formation. bacteria isolated from stem G. using mineral medium containing extracts carbon source. selection was carried out based their capability grow selective media different sources (i.e. CMC, xylan) determine enzyme properties. Bacterial high activities form zone degradation that chosen potential planta assay. Five (strain BPSA2a, BPSA2b, BPSB1, BPSB10, BGG2) have lignocellulolytic bacteria. In assay showed after 30 days injection, infection occurred decay surface bark, discoloration inside, widen varying color intensities, burned. Inoculated caused production number extract yield agarwood, respectively, 6,78 %; 6,67 5,30 4,57 %, 4,50 %. Dihydroagarofuran β-agarofuran are most compounds these resins.
