Characterization results showed a morphological and physiological similarities to the characteristics of Bacillus subtillis. Physiology assay results such as catalase test, oxidase test, starch hydrolysis test, motility test and test of temperature on the growth of the bacteria showed a positive result on the each isolate. Six isolates had a convex surface and six isolates had a flat surface. The PDF file you selected should load here if your Web browser has a PDF. Results showed that the morphological characterization such as colony color, colonies form and colonies edges of the bacteria had similarities each others, but there was a difference on the surface of morphology colony. KARAKTERISTIK MORFOLOGI BAKTERI SIMBION SPONS MENYERUPAI Cribochalina sp DARI. Isolation was performed from oil palm plant organs such as root, stems and leaves of oil palm plants. The location of sampling was at the district of Asahan North Sumatera. syringae dapat ditemukan pada tanaman, tanah, dan udara, tetapi umumnya memiliki habitat pada permukaan daun berbagai tanaman sehingga termasuk bakteri. Plants samples was taken by survey method. The purpose of the research is to observe the characteristics of the endophytic Bacillus sp. can be used as a biological pesticide and biological fertilizers which is useful for plants. There are many species of endophytic bacteria living inside tissue oil palm plant which play a beneficial role for plant. Based on the results of the identification of physiological and morphological characteristics, it is evident that the endophytic and rhizobacterial bacteria tested have the same character as Bacillus spp.Endophytic bacteria are bacteria that infect and live in plant tissue, including oil palm plant tissue. Also, 66 isolates were isolated from the soil around the rhizosphere area. Daur hidup tipe bakteri pembentuk spora (dimodifikasi dari SLEPECKY & HEMPHILL. A total of 46 endophytic bacterial isolates were isolated from healthy clove roots, stems, leaves and flowers. The purpose of this study was to identify the physiological and morphological characteristics of endophytic and rhizobacterial isolates obtained from clove plants. Endophytic bacteria and rhizobacteria have been reported as potential biological control agents for many plant diseases because of their safety in humans and non-target organisms. The use of biological control agents that form a symbiotic mutualism in their host plants can be used as an effort to obtain quality clove seeds. One of the determining factors in disease control is the use of superior seeds which have good quality and quantity. Identification, characterization, endophytic bacteria, rhizobacteria Abstract
