Abstract
The inoculation of plant growth-promoting bacteria (PGPB) as biofertilizers is one of the
most efficient and sustainable strategies of rhizosphere manipulation leading to increased plant
biomass and yield and improved plant health, as well as the ameliorated nutritional value of fruits
and edible seeds. During the last decades, exciting, but heterogeneous, results have been obtained
growing PGPB inoculated plants under controlled, stressful, and open field conditions. On the other
hand, the possible impact of the PGPB deliberate release on the resident microbiota has been less
explored and the little available information is contradictory. This review aims at filling this gap:
after a brief description of the main mechanisms used by PGPB, we focus our attention on the
process of PGPB selection and formulation and we provide some information on the EU regulation
for microbial inocula. Then, the concept of PGPB inocula as a tool for rhizosphere engineering is
introduced and the possible impact of bacterial inoculant on native bacterial communities is
discussed, focusing on those bacterial species that are included in the EU regulation and on other
promising bacterial species that are not yet included in the EU regulation.
