With growing world population, there is an exponential increase in demand for food. The use of chemical fertilizers to improve crop productivity is associated with considerable health risks, environmental hazards, and costs. In this scenario, biofertilizers or microbial fertilizers appear to be an important alternative strategy. Therefore, this manuscript was proposed document the importance of biofertilizers and plant growth promoting rhizobacteria (PGPR) as candidates for it production. The various underlying mechanisms promoting the growth of plants, different types and comparison with chemical fertilizers are compiled in this review and the potential for developing a sustainable agriculture.

Palabras clave : biocontrol; biofertilizers; chemical fertilizers; nitrogen fixation; PGPRs.
