Volatile emission compounds from plant growth-promoting bacteria are responsible for the antifungal activity against F. solani.

ABSTRACT: The aims of this work were to screen isolated bacteria with a dual capacity: to inhibit Fusarium solani and to promote plant growth. Also, volatile compounds that would be responsible for that effect were identified. Seventy bacterial strains from the air, agricultural soils, hydrocarbons-contaminated soils, and extremophile soils were tested. The former were identified by Matrix-Assisted Laser Desorption/Ionization-time of flight mass spectrometry and 16S rDNA sequencing. The plant growth-promoting bacteria (PGPB) and their capability for phosphate solubilization, siderophores production, and indole production were determined. Twenty isolates from Bacillus and Pseudomonas genera inhibited the mycelial growth up to 40% in direct assays. Eleven isolates significantly in
