Fusarium head blight is a severe disease of wheat, corn, barley, and other grain and occurs in all regions worldwide. Several bacteria and fungi have been found to inhibit the growth of Fusarium graminearum. Among the antimicrobial agents identified, Bacillus is the most compelling antibiotic-producing strain, and it has more advantages than other biocontrol microorganisms due to its inherent endospore formation and resistance to extreme conditions.

Paenibacillus polymyxa 7F1 was isolated from the rhizosphere of a wheat field, and it was shown that Paenibacillus polymyxa 7F1 showed high antifungal activity against all fungi strains tested in this study.


Antifungal activity of Paenibacillus polymyxa 7F1 against seven pathogenic fungi. 1. Fusarium equiseti, 2. Fusarium verticillioide, 3. Fusarium semitectum, 4. Fusarium graminearum, 5. Colletotrichum gloeosporioides, 6. Fusarium proliferatum, 7. Fusarium oxysporum

The antibiotics produced by Paenibacillus polymyxa 7F1 included lipopeptides such as iturin A and surfactin.
