Endophytes refers to as the microorganisms that reside in a host plant and are in a relationship with the abiotic and biotic factors. These factors are responsible to influence the function and structure of the communities. There are few studies done about bacteria of endophytic from the tress of forest, though there have various studies been conducted. The recent study has the aim to isolate some endophytic bacteria from Borneo base forest of Universiti Putra Malaysia Kampus Bintulu (UPMKB). The test has been conducted for the growth of plant. About 61 bacteria have been isolated and tested to produce IAA or, indole-3- acetic acid, siderophore production, and solubilize phos-phate. About a number of 35 isolates have been discovered to solubilize the phosphate and 70 percent of the phosphate belong to bacteria have produced. There have found 220 to 99 g/ml of concentration for IAA. In order to produce siderophore, there found 8 isolates. Enterobacter sp. and Pantoea has been found as the general that is most abundant and recovered from the DNA se-quencing of 16s ribosome. Different bacteria had been tested in vitro to promote the ability for the growth of plant. There have found 5 strains capable for the growth of the tomato plant. This study may be the first ever report for performing the isolation of the plant growth that promotes the Uncaria borneensis by promoting endophytic bacteria. It should be concluded that, the successful interaction between the strains of endophytic such as the Uncaria tree, J-112, J-111 provides benefits in a long term and direct the development and employ those strains as biofertilizer to produce certain crops and reduce application of fertilizer
