Pseudomonas aeruginosa producer of metabolite with antimicrobial activity against Burkholderia glumae

Abstract

The present study had as objective to evaluate in vitro antimicrobial activity of endphytes bacteria associated with Neem (Azadirachta indica) against Burkholderia glumae. The inhibitory activity of endophytic bacteria against B. glumae was evaluated by antagonism, using the technique of diffusion in agar with sensitive records. Once identified the endophytic bacteria inhibitory potential, used discs medium numbers 3 for production of secondary metabolites, to test their inhibition against B. glumae by Elisa plate microdilution methods. The results showed an inhibition of 50% of the growth against B. glumae, the identification with API 20 NE kit found in 99,55% to the species Pseudomonas aeruginosa.
