Abstract

Aims: Assess the potential for A. flavus biocontrol isolates from different geographic regions to secrete metabolites with inhibitory properties against mycotoxigenic isolates.

Methods and results: Using four Aspergillus isolates from Arizona, Georgia, and Mississippi, mycotoxin producing isolates from each region were grown on media previously colonized by a biocontrol isolate to assess the inhibition potential of biocontrol-produced extrolites. Significant changes in growth and/or mycotoxin production were observed.

Conclusions: Production of inhibitory extrolites is a trait shared by biocontrol isolates. Mycotoxin reduction was not directly proportional to growth for most isolates, since extrolites secreted by the examined biocontrol isolates were able to greatly reduce mycotoxin production even if growth was minimally inhibited. Only the Georgia isolates exhibited a linear relationship between reduced growth and mycotoxin reductions, indicating their mycotoxin reductions were primarily due to reduced growth.

期刊介绍： Journal of & Letters in Applied Microbiology are two of the flagship research journals of the Society for Applied Microbiology (SfAM). For more than 75 years they have been publishing top quality research and reviews in the broad field of applied microbiology. The journals are provided to all SfAM members as well as having a global online readership totalling more than 500,000 downloads per year in more than 200 countries. Submitting authors can expect fast decision and publication times, averaging 33 days to first decision and 34 days from acceptance to online publication. There are no page charges.
