and have numerous attractive characteristics for their potential use in biological control, including: suppression of diseases by the production of antimicrobial compounds that inhibit the development of pathogens; competition in colonizing the niche and for nutrients; activation of the host defense system by induced systemic resistance (ISR); and stimulatory effects on plants due to the increased availability of nutrients such as nitrogen, phosphorus and amino acids. Bacillus subtilis is a grampositive,
spore-forming bacterium that is naturally present in the roots of plants. Today, it is recognized as a powerful tool in biological
control because of its ability to promote plant growth under
limited conditions of soil phosphorous through phytase production
and the inhibition of phytopathogens achieved by producing extracellular
enzymes. In addition, it stimulates the plant’s own
defenses and produces a variety of antibiotics
