Evaluation of in vitro plant growth promotion activity of Bacillus spp. isolated from corn (Zea mays L.)

The objective of this study was to molecularly characterize endophytic bacteria isolated from corn plants (Zea mays L.), as well as to evaluate in vitro the metabolic and antagonistic activity against phytopathogenic fungi. White corn plants, variety 4032 dekalb hybrid pioneer, were collected during the autumn-winter cycle 2022-2023; Endophytic bacteria were isolated from tissue (leaf, stem and root); obtaining eleven Gram positive isolates, eight beta-hemolytic and three gamma-hemolytic with which the work was carried out.
