Production of Volatile Organic Compounds by Trichoderma in Media Containing Different Amino Acids and Their Effect on Selected Wood Decay Fungi
Summary
The paper describes an experiment to evaluate the effect of subtle changes to the amino acid composition
of the growth medium on the production of volatile organic compounds (VOCs) by a Trichoderma
aureoviride isolate and the consequent inhibition of wood decay fungi. A synthetic medium was produced
to represent the C:N ratio and major amino acid content of Scots pine sapwood. Changes in the
amino acid content of the medium produced very significant differences in the VOC output produced by
the Trichoderma isolate and in the levels of inhibition of the target wood decay fungi. Principal component
analysis of the VOC profiles indicated that aldehyde and ketone components were associated with
the greatest inhibition of the target fungi. The implications of the results for the use of Trichoderma isolates
as biological control agents of decay fungi in wood are discussed.
