Isolation and Characterization of Endophytic Bacteria from the Leaves of Carica papaya L.
- Endophytic bacteria were isolated from the leaves of Carica papaya L. (papaya). The leaf samples were collected from the Campus of University of Mandalay. This experiment was carried out at the Microbiology Laboratory, Department of Botany, University of Mandalay from December 2017 to August 2018. The six bacterial strains, TS 1 - TS 6 were isolated and characterized based on their colony morphology and biochemical tests. Each of isolates was characterized by the morphological characters (shape, colony, colour, cell size, gram staining, aerobic growth and motility) and biochemical tests (catalase, oxidase, starch hydrolysis, lysine decarboxylase, urea hydrolysis, sugar fermentation such as dextrose, glucose, manitol and sucrose, citrate utilization, methyl red, triple sugar iron (TSI) and nitrate reduction) were carried out. The isolated bacteria were confirmed TS 1 as Mycobacterium sp., TS 2 as Bacillus sp., TS 3 as Staphylococcus sp., TS 4 as Micrococcus sp. TS 5 as Streptococcus sp. and TS 6 as Enterobacter sp..
