A. Bruce et al., Production of volatile organic compounds by Trichoderma in media containing different amino acids and their effect on selected wood decay fungi, HOLZFORSCH, 54(5), 2000, pp. 481-486
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 vol
atile 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 sapw
ood. Changes in the amino acid content of the medium produced very signific
ant differences in the VOC output produced by the Trichoderma isolate and i
n the levels of inhibition of the target wood decay fungi. Principal compon
ent analysis of the VOC profiles indicated that aldehyde and ketone compone
nts were associated with the greatest inhibition of the target fungi. The i
mplications of the results for the use of Trichoderma isolates as biologica
l control agents of decay fungi in wood are discussed.
