Abstract

Beauvericin (BEA) is a proven and potent antibiotic compound useful for bio-control and a potential antifungal and anticancer agent for human. This study was to evaluate and optimize the nutrient medium for BEA production in mycelial liquid culture of a high BEAproducing fungus Fusarium redolens Dzf2 isolated from a medicinal plant. Among various organic and inorganic carbon and nitrogen sources, glucose and peptone were found the most favorable for the F. redolens Dzf2 mycelial growth and BEA production. Through a Plackett-Burman screening test on a basal medium, glucose, peptone, and medium pH were identified as the significant factors for mycelial growth and BEA production. These factors were optimized through central composite design of experiments and response surface methodology, as 49.0 g/L glucose, 13.0 g/L peptone and pH 6.6, yielding 198 mg/L BEA (versus 156 mg/L in the basal medium). The BEA yield was further increased to 234 mg/L by feeding 10 g/L glucose to the culture during exponential phase. The results show that F. redolens Dzf2 mycelial fermentation is a feasible and promising process for production of BEA.
