Effects of volatile aldehydes from Aspergillus-resistant varieties of corn on Aspergillus parasiticus growth and aglatoxin biosynthesis.

The effects on Aspergillus parasiticus of the corn dirived volatile compounds, ndecyl aldehyde, hexanal and octanal, were measured. The three compounds were previously found  to be variably expressed in five Aspergillus resistant maize strains and three susceptible strains. A. parasiticus radial growth was restricted  least by n-decyl aldehyde and most by octanal, Treatments of 100 uL of both hexanal and octanal were found to completely inhibit radial growth of the fungus using an agar plate assay method. Whill the volatile compound n-decyl aldehyde treated colonies had a predominance of uniquely aerial hyphae. Furthermore, aflatoxin production by the fungus was reduced by n-decyl aldehyde and hexanal, but was stimulated by octanal.
