Actinobacteria are known to produce various secondary metabolites having antibiotic effects. This study assessed the antimicrobial potential of actinobacteria isolated from the rhizosphere of Caesalpinia pyramidalis Tul. from the Caatinga biome. Sixty-eight actinobacteria isolates were evaluated for antimicrobial activity against different microorganisms by disk diffusion and submerged fermentation, using different culture media, followed by determination of minimum inhibitory concentration (MIC) and chemical prospecting of the crude extract.

Biotechnological prospecting of foliar endophytic fungi of guaco (Mikania glomerata Spreng.) with antibacterial and antagonistic activity against phytopathogens

J. C. Polonio, Almeida, T. T., Garcia, A., Mariucci, G. E. G., Azevedo, J. L., Rhoden, S. A., and Pamphile, J. A., Biotechnological prospecting of foliar endophytic fungi of guaco (Mikania glomerata Spreng.) with antibacterial and antagonistic activity against phytopathogens, vol. 14, pp. 7297-7309, 2015.

Mikania glomerata (Spreng.), popularly known as “guaco”, is a plant from the Asteraceae family that has many therapeutic properties. The use of medicinal plants has been examined in studies on endophytic diversity and bioprospecting; endophytes inhabit the interior of plants without harming them. Microorganism-host complex interactions are related to the production of compounds that may confer resistance to pathogens or to production of bioactive compounds or growth regulators. In this study, we evaluated foliar endophytic fungi of M.
