Impact of Pediococcus pentosaceus strain L006 and its metabolites on fumonisin biosynthesis by Fusarium verticillioides
چکیده انگلیسی

The aim of this work was to study the effectiveness of a Pediococcus pentosaceus strain L006, isolated from maize leaf and previously characterised for its high antifungal efficiency, on fumonisin biosynthesis by Fusarium verticillioides. Studies performed in GYEP medium supplemented with amylopectin showed a significant increase in fumonisin production when the F. verticillioides strain was simultaneously co-inoculated with the P. pentosaceus strain or inoculated in a three-day-old culture of this lactic acid bacteria. Our studies also demonstrated that some extracellular metabolites produced in MRS medium by the P. pentosaceus strain L006 were able to significantly reduce fumonisin production in liquid medium as well as on maize kernels. Fumonisin yields by F. verticillioides inoculated on autoclaved maize kernels were reduced by a factor ranging from 75% to 80% after 20 days of incubation. Our results illustrate the potential risk linked to the use of an antagonistic bacterial agent to manage fumonisin contamination, while emphasizing the potential use of bacterial metabolites to counteract fumonisin accumulation in kernels.

► Biocontrol of mycotoxin production. ► We examine the potential of P. pentosaceus strain L006 to control fumonisin production. ► This bacteria produces efficient antifungal and “antimycotoxin” metabolites. ► However, under certain conditions it stimulates fumonisin production.
