High-performance liquid chromatography-based characterization of fengycin produced by Bacillus amyloliquefaciens against Fusarium graminearum and Rhizoctonia solani

الملخص EN

A substantial loss of crop production worldwide is attributed to fungal phytopathogens.

the most important economic pathogens among these fungal phytopathogens are fusarium graminearum and rhizoctonia solani, which cause a wide range of plant diseases.

in the present study, bacillus amyloliquefaciens secondary metabolite fengycin was identified by high-performance liquid chromatography (HPLC) and in vitro screened against the fusarium graminearum and rhizoctonia solani.

based on the HPLC result, fengycin was identified at 215nm wavelength, a retention time of 5-7 minutes, and a peak area of 3.914.

the obtained results indicated that fengycin (1, 1/2, 1/4, and 1/8) concentrations have a significant effect (p<0.005) on the growth of F.

graminearum and R.

solani.

the current study concluded that B.

amyloliquefaciens secondary metabolites fengycin have a high potential to inhibit the growth of F.

graminearum and R.

solani.
