Evaluation of the antimicrobial potential of actinobacteria strains isolated from mangrove soils in the municipality of São Caetano de Odivelas – Pará, Brazil

The actinobacteria compose a phylum of Gram-positive bacteria that possess a wide morphological and physiological variety. They are cocci or bacilli shaped and their reproduction is characterized by the formation of spores and septate pseudo hyphae similar to fungi. Physiologically, they have a great capacity to produce secondary metabolites, which give this group of bacteria a high pharmacological and commercial value. The aim of this work was to isolate and evaluate the antimicrobial potential of strains isolated from mangrove soils in the municipality of São Caetano de Odivelas-PA. As results, from the 19 isolates, 11 strains, showed a good performance against the tested pathogenic bacteria - S. aureus, E. coli and K. pneumoniae.
