Indirectly, they suppress pathogens mediated by competition and the production of antimicrobial compounds and lytic enzymes.

Rhizobacteria can indirectly or directly promote positive effects on plants. 2 Of these, some bacteria positively affect plants and have been designated as plant growth-promoting rhizobacteria (PGPR). Bacteria are estimated to occupy between 7% and 15% of the total root surface area. Soil microorganisms coexist in association with plant roots and interfere with plant performance and microbial community structure. 1 However, efficient antagonists must be obtained for biological control to become a reality. In this context, the focus of biological control studies reflects the desire of several sectors to develop sustainable methods for plant disease control. Thus, we clearly observed that bacteria that produced more compounds related to phytopathogen biocontrol and/or plant growth had a higher efficacy for nematode biocontrol, which validated the selection strategy used.Д¬oncerns regarding food safety and the environment have led to reduced use of agrochemicals and the development of sustainable agriculture. The most efficient bacteria (producing at least five compounds related to phytopathogen biocontrol and/or plant growth), 86 in total, were evaluated for their biocontrol potential by observing their ability to kill juvenile Mesocriconema xenoplax. Most bacterial isolates with biocontrol potential were isolated from rhizospheric soil. Bacteria from different plant species (rhizosphere or phylloplane) exhibited differences in the ability to produce the compounds evaluated. Among the compounds which often determine the success of biocontrol, 43% produced compounds which inhibit mycelial growth of Monilinia fructicola, but only 11% hydrolyzed chitin. Proteolytic activity was most frequently observed among the bacterial isolates. Of the 1219 bacterial isolates, 92% produced one or more of the eight compounds evaluated, but only 1% of the isolates produced all the compounds. The production of compounds related to phytopathogen biocontrol and/or promotion of plant growth in bacterial isolates was evaluated by measuring the production of antimicrobial compounds (ammonia and antibiosis) and hydrolytic enzymes (amylases, lipases, proteases, and chitinases) and phosphate solubilization.
