Resumen
- Fusarium oxysporum (FOX) is one of the most difficult plant pathogens to control leading to important economic losses in several crops owing to Fusarium-wilt disease. Biological control through beneficial rhizobacteria has high potential to reduce the devastating effects caused by FOX. Bacillus amyloliquefaciens strain Bs006 has potential as plant growth promoter and biocontrol agent against cape gooseberry wilt disease. Although plant growth promoting phenomenon had been consistent in previous experiments, the biocontrol activity by Bs006 was variable, suggesting that biotic and abiotic factors in the rhizosphere affect the efficacy of Bs006. Thus, the main goal of this doctoral research was contribute to knowledge of Bs006-FOX-cape gooseberry-environment interactions. Results show that Bs006 synthesizes cyclic lipopeptides (CLPs) from the iturin, fengycin and surfactin families. However, incubation temperature and culture media affect the production of CLPs
