Stenotrophomonas maltophilia impedes Bacillus biocontrol of tomato wilt disease by degrading its lipopeptide antibiotics.

ABSTRACT: Harnessing antibiotic-producing microorganisms that antagonize pathogens represents a sustainable approach for plant disease management. However, biocontrol agents that are effective in the laboratory often have diminished or variable performance in the field. It is often assumed that microbial interactions within the plant rhizosphere can influence the performance of biocontrol agents. To validate this hypothesis, we established a tripartite bacterial model system based on field investigations, involving antibiotic producers (Bacillus amyloliquefaciens P224, Bacillus subtilis P165, and Bacillus velezensis P63), an antibiotic degrader (Stenotrophomonas maltophilia P373), and a bacterial plant pathogen (Ralstonia solanacearum PA1). The selected Bacillus species antagonize R. solanacearum an
