Trichodiene as a volatile marker for trichothecenes biosynthesis.

The ability of Fusarium strains, belonging to five different species, to produce volatile compounds and trichothecenes was monitored by GC/MS.  Isolates were grown for 21 days on autoclaved wheat kernels.  The volatiles were collected after 3 and 21 days on Tenax GR traps using a dynamic headspace method, and immediately after volatiles collection the cultures were checked for trichothecenes.  Of nine analysed strains, seven were toxigenic and produced both types A and B trichothecenes.  Among volatile metabolites, sesquiterpene hydrocarbon trichodiene was produced exclusively by toxigenic strains representing four species and was detected in all toxigenic strains after 3 days incubation.  Trichodiene presence can serve as an indicator for undergoing trichothecene biosynthesis.
