Eight endophytic bacterial strains (Bacillus spp., Stenotrophomonas maltophilia, and Pseudomonas geniculata) recovered from healthy cultivated tomato (Solanum lycopersicum L.) were screened for their plant growth-promoting potential on tomato plants challenged with Fusarium oxysporum f. sp. lycopersici (FOL) and for their in vitro and in vivo antifungal activity against FOL. S. maltophilia CT16 and Bacillus subtilis subsp. inaqosorum CT43 and their filtrates were the most efficient in controlling disease by 55-87.5% and in improving growth parameters in inoculated tomato plants by 8.4-46.8%. Pathogen sporulation was inhibited and FOL mycelial growth was reduced using whole-cells and filtrates of the eight strains, and organic extracts from the two active ones.
