Degradation of zearalenone by the extracellular extracts of Acinetobacter sp. SM04 liquid cultures

A bacterium (designated SM04) which can rapidly grow on zearalenone (ZEN) as sole carbon and energy source was isolated from agricultural soil. On the basis of 16S rDNA sequencing analysis, strain SM04 was classified as a bacterium belonging to the Acinetobacter genus. In this study, the biodegradat...

Description
Summary:A bacterium (designated SM04) which can rapidly grow on zearalenone (ZEN) as sole carbon and energy source was isolated from agricultural soil. On the basis of 16S rDNA sequencing analysis, strain SM04 was classified as a bacterium belonging to the Acinetobacter genus. In this study, the biodegradation of ZEN by the extracellular extracts of strain SM04 liquid cultures in M1 medium and Nutrient Broth medium was examined using HPLC analysis, APCI-MS analysis, and MTT (tetrazolium salt) cell proliferation assay. Results showed no ZEN and other equally estrogenic metabolites were found after 12 h when ZEN was treated with the extracellular extracts of M1 cultures, but no significant ( P
