Phosphate solubilization, indole acetic acid synthesis and biocontrol by streptomyces isolates
Actinobacteria of the genus Streptomyces have great potential in producing several bioactive compounds. With that, the objective was to characterize morphologically isolates of Streptomyces, to evaluate the phosphate solubilization and the production of indole acetic acid (IAA) and the antagonistic activity to the pathogenic fungi Curvularialunata andColletotrichum sp. The morphological characterization presented eight-gram positive isolates from the nine evaluated. Six isolates presented a colony greater than 2 mm, seven with elevated colony and five transparent.
