Maize ( Zea mays L.) is an important crop in the tropical climatic region and one of the three major food staple crops for the world’s population. In addition, we suggest that Enterobacter strains LGMB221 and LGMB235 and Escherichia strain LGMB159 might represent new species, indicating the high diversity of bacteria in maize rhizosphere that remains to be determined. The next steps involve evaluations under field conditions to confirm if these isolates have biotechnological potential as inoculants for the maize crop. LGMB152 showed the best enzymatic results, indicating that it might play a role against pathogens, a premise supported by the antagonist activity observed. LGMB242 that showed the high potential for growth promotion, acting in the early stage of maize seedlings development. The best results were observed for Enterobacter sp. All isolates evaluated were positive for at least one of the parameters evaluated-growth promotion, enzymatic production or bio control. In this study, we investigated the bacterial community isolated from maize roots in order to evaluate their capacity of growth promotion as well as of inhibition of fungal species associated with maize leaf diseases. The increase in maize production has been achieved with a high use of fungicide however, in view of a more sustainable agriculture plant growth promoting bacteria have been explored aiming for the replacement of chemical fertilizers and biological control. Maize ( Zea mays L.) culture has a great importance in several countries, especially in Brazil the third-largest world producer.
