Highlights
- •
Bacteria had broad-spectrum activity against phytopathogenic fungi (>50% inhibition).
- •
Selected isolates were identified with molecular methods and analyzed for plant growth-promoting activities.
- •
The selected isolates had a good survival rate in a cost-effective medium.
- •
Assessed medium can be used for commercial fermentation of bio-control agents.
