Preliminary study on the influence of inoculation of tomato (solanum lycopersicum) plants with a microbial consortium on soil bacterial communities

Abstract

Recent studies demonstrate the potential of microbial consortia, rhizobacteria and rhizofungi, as plant biostimulants. On the other hand, plants depend on microorganisms to use soil as a growth medium, and synergy between the two is important for their survival. They are allies of plants and govern several fundamental processes related to their growth. Inoculation these microoganisms can cause changes in the structure of the native microbiota, which is crucial to be considered with respect to the safety of introducing microorganisms into the environment. Certain groups of microorganisms can be increased, others can be inhibited, and in some cases, the application of plant growth-promoting microorganisms does not cause any change in microbial populations. The objective of this work was to carry out a preliminary evaluation of the effect of inoculating tomato (Solanum lycopersicum) plants with the biostimulant consortium based on Trichoderma harzianum ITEM 3636 and Pseudomonas putida PCI2 on the structure of soil bacterial communities.
