Methods: Samples of roots and stems of C. jamacaru and Melocactus zehntneri were collected from the Aiuaba ecological Station in Brazilian semi-arid region. Bacterial isolates were cultured in semi-solid N-free media and grown in Pikoskaya's and GL media phosphate solubilizing. In seedling assays, strains of Rhizobium (CAC 01), Enterobacter (CAC 02 and CAC 11), Pseudomonas (CAC 03) and Burkholderia (CAC 07 and CAC 10)were tested. Results: Culturable endophytic bacteria were observed in all samples from cacti, but the populations were low. Representatives of eight groups were identified based on partial sequences of 16S rDNA and were related to Rhizobium, Burkholderia, Enterobacter, Pseudomonas, and Pantoea species. The colonization of seedlings with endophytic bacteria was observed, but biomass accumulation did not show a significant increase. All strains were able to grow on solid Pikoskaya's medium. Conclusions: The bacterial strains didn't increase significantly the cactus biomass during 6months of cultivation, but showing potential phosphate solubilizing activity.
