AGRICULTURAL COMPOSITION COMPOSED BY CONSORTIUM BETWEEN Azospirillum sp. and Pseudomonas sp., PRODUCTION PROCESS AND INCREASED STABILITY THEREOF, AND USE AS PROMOTOR OF PLANT GROWTH FOR AGRICULTURAL APPLICATION

Abstract

The present invention refers to an agricultural composition that comprises a mixture of Azospirillum brasilense and Pseudomonas fluorescens in a single commercial inoculant product that promotes increased stability and cellular viability due to the synergism between these microorganisms, and which surprisingly increases the shelf-life achieved by a differentiated industrial process. The industrial process of the mixture of Azospirillum and Pseudomonas as product inoculant plant growth promoting is composed by steps of: (a) fermentation of the microorganisms to obtain an agricultural composition with plant growth promotion action through biological mechanisms to fix nitrogen, biosynthesis of auxins, siderophores and solubilization of phosphorus; (b) stabilization of the product biotechnological inoculant composed by the mixture of Azospirillum and Pseudomonas in a technical solution that enables the mixture of the parts, presented in a single package. The synergism demonstrated is mainly connected to (i) the high production of EPS by Azospirillum which is consumed by Pseudomonas as energy source and (ii) to the production of organic acids by Pseudomonas which enables the maintenance of cellular viability of the Azospirillum.
