Bioprospection, morphological and biochemical characterization and evaluation of the antimicrobial activity of the bacterial strains of chicken breeding soil (Gallus gallus domesticus) in the city of Igarapé-Açu, Pará

Abstract

The soil is a propitious place for the development of decomposer microrganisms, mainly fungi and bacteria. The soil colonization from those organisms occurs in places with great availability of organic matter, like the rhizosphere and animal breeding soils, like poultry farming. Among the microrganisms present in this type of soil, there are the actinomicetes, which belong to phylum of gram-positive bacteria with filamentous estructures that constitute aerial mycelia. The objective of this article was to isolate, bioprospect, characterize morfologically and biochemically and to assess the antimicrobial potential of strains of bacterias from chicken breeding in the city of Igarapé-Açu, Pará. As a result, bacterial colonies with variable features that indicate the genus Actinobacteria were found, amongst them one showed potential antibacterial against a strain of Klebsiella pneumoniae
