Isolation and characterization of filamentous fungi capable of degrading the mycotoxin patulin

ABSTRACT: Abstract Patulin is a toxic secondary metabolite synthesized by various fungal strains. This mycotoxin is generally toxic to microorganisms as well as mammals due to its reactivity with the important cellular antioxidant glutathione. In this study, we explored the presence of microorganisms capable of degrading patulin. Microorganisms were screened for the ability to both grow in culture medium containing patulin and reduce its concentration. Screening of 510 soil samples resulted in the isolation of two filamentous fungal strains, one of which, Acremonium sp. TUS‐MM1 was characterized in detail. Liquid chromatography‐mass spectrometry and nuclear magnetic resonance analyses revealed that TUS‐MM1 cells degraded patulin to desoxypatulinic acid. In addition, extracellular components of strai
