Effect of Saccharomyces cerevisiae consumption on the pathogenicity of Beauveria bassiana in Protaetia brevitarsis

Beauveria bassiana is a common fungal pathogen of Protaetia brevitarsis larvae, and although it is less common than Metarhizium anisopliae, the pathogen still poses a great risk to humans and animals that consume infected insects, owing to B. bassiana`s production of toxins like beauvericin and myco...

Summary:Beauveria bassiana is a common fungal pathogen of Protaetia brevitarsis larvae, and although it is less common than Metarhizium anisopliae, the pathogen still poses a great risk to humans and animals that consume infected insects, owing to B. bassiana`s production of toxins like beauvericin and mycotoxin. Interestingly, the beneficial microorganism Saccharomyces cerevisiae possesses antifungal properties. In the present study, we found that S. cerevisiae inhibited the growth of B. bassiana by 97% and that S. cerevisiae failed to harm P. brevitarsis when administered via intracoelomic injection (1 × 10 7 cfu/mL). In addition, we also found that S. cerevisiae consumption increased the survival time of percutaneously infected P. brevitarsis larvae by 5 d and reduced the mortality of infected larvae by 12%. Therefore, S. cerevisiae is expected to be useful in the prevention and control of B. bassiana in the production of P. brevitarsis larvae.
