Bromeliads inhabit different environments and many are found as epiphytes. These plants are often subjected to periods of water and nutrient shortage. For their survival, the epiphytic bromeliads are endowed with different morphological and physiological adaptations. Guzmania monostachia, an epiphytic tank-bromeliad, has been extensively studied because of its great photosynthetic plasticity. In Brazil, it is found only in the northeast region, in an area that is suffering deforestation. In addition to the already known adaptations, the interactions with microorganisms may also play a role in the nutrition process of epiphytic bromeliads, but little is known about that. Therefore, this study collected G. monostachia leaves in their natural environment in Brazil and in a greenhouse to isolate nitrogen fixing (diazotrophic) bacteria and characterize them phylogenetically. The isolation was performed from both the outside (epiphytic bacteria) and the inner part (endophytic) of different leaf portions (apex, middle and base). The bacteria were selected using the acetylene reduction assay (ARA) and using four different media that do not contain reduced nitrogen source. The strains were identified by 16S rRNA. Most of the isolated strains belong to the group of Proteobacteria (Family Enterobacteriaceae, Pseudomonas, Stenotrophomonas, Brevundimonas, Burkholderia and Dyella). In addition, strains belonging to Firmicutes group (Paenibacillus) and Actinobacteria (Mycobacterium and Micrococcus) were also isolated. Most of the genera
