  Ten nonpathogenic bacterial isolates, recovered from Datura stramonium organs, and successfully colonizing the internal stem tissues of tomato cv. Rio Grande were screened for their ability to suppress tomato Fusarium wilt, caused by Fusaium oxysporum f. sp. lycopersici (FOL), and to enhance tomato growth. S37 and S40 isolates were found to be the most effective in decreasing leaf yellowing by 94-88% and the vascular browning extent by 96-95%, respectively, as compared to FOL-inoculated and untreated control. A significant enhancement of growth parameters was recorded on tomato plants inoculated or not with the pathogen. The two bioactive isolates were morphologically and biochemically characterized and identified using 16S rDNA sequencing genes as Stenotrophomonas maltophilia str. S37 and Bacillus mojavensis str. S40. Screened in vitro for their antifungal activity toward FOL, these .. View More»
