Abstract
Agarwood is one of the most expensive, sacred and valuable woods used in the biotechnology industry. This natural raw material is in high demand as a commodity and can be used to manufacture a variety of products. Isolating a microbe from its environment is crucial because several bacterial strains can produce novel compounds for biotechnological applications. Exploration of bacterial strains, such as bacterial endophytes, has been associated with bioactive compounds of the agarwood plant. The purpose of this study was to isolate and identify bacteria from Agarwood trees in the Kaeng Hang Maeo Sub-district of Chanthaburi Province, Thailand by using molecular biology techniques. A colony PCR technique without prior DNA extraction for rapid and simple detection of bacteria was performed. After the DNA sequence analysis, the results showed that most populations in the normal layer are belonged to Pantoea dispersa (99%). Through analysis of phylogenetic tree by neighbor-joining method, the sequences of the 16s rRNA gene were analyzed to understand evolutionary relationships of bacteria found in agarwood. In conclusion, good amplification of the 16s rRNA sequence (1.5 kb) was detected with the specificity of the target sequences of the 16s RNA. In addition, the isolated bacterial strains are the most common species in agarwood, however, there has been no previous research on isolating these bacterial strains in Aquilaria crassna.
