Effect of volatiles from bacteria and yeast on the growth and pigmentation of sap-stain fungi
2000 - IRG/WP 00-10331
Sapstain fungi cause deterioration of wood due to colonisation by pigmented hyphae but without producing significant strength losses. This is due to the production of melanin in the fungal cell walls of the staining fungi. Any biological control strategy targeted against this type of deterioration would therefore be considered successful if it inhibited either fungal growth or pigment production. ...

The effect of Trichoderma volatiles on the growth and enzyme production of Serpula lacrymans
2000 - IRG/WP 00-10332
Although various authors have reported the biological control of Serpula lacrymans by Trichoderma spp. the mode of antagonism employed by Trichoderma is not yet clear. The work presented here concentrates on the production of anti-fungal volatiles for inhibition of S. lacrymans growth. Volatile mediated interactions were examined between four S. lacrymans isolates and a range of nine known Trichod...

Assessment of the Inhibition of wood decay fungi by volatile organic compounds identified from Trichoderma spp.
1999 - IRG/WP 99-10302
Previous research identified five volatile organic compounds produced by Trichoderma spp. that may be inhibitory to wood decay fungi. The effects of four of these volatile organic compounds, 2-propanone, 2-methyl-1-butanol, heptanal and octanal were tested over a range of concentrations against four selected wood decay fungi. The fungi were incubated in malt extract broth under appropriate conditi...

Effect of Volatiles from Trichoderma species on the regulation of protein synthesis in Serpula lacrymans isolates
2002 - IRG/WP 02-10440
The growth of wood decay fungi has previously been shown to be inhibited by volatile organic compounds (VOCs) from selected Trichoderma isolates. No mechanism of action has however been established for such inhibition. This paper reports the effects of VOCs produced by Trichoderma pseudokoningii, T. viride and T. aureoviride on the growth of four dry rot isolates and corresponding protein synthesi...

Analysis of volatile organic compounds (VOC's) from Trichoderma spp.: effect of media composition on VOC production and level of inhibition of wood decay fungi
1997 - IRG/WP 97-10207
Production of volatile organic compounds (VOC's) by two Trichoderma isolates grown on either malt extract or minimal media was examined and statistically assessed to identify which VOC's were predominantly produced on each of the two media types. The VOC's were captured onto chromatographic absorbent from above the cultures of the fungi before being analysed by integrate...

Identification and inhibitory effect of volatiles from different ages of a Trichoderma aureoviride culture on selected wood decay fungi.
1995 - IRG/WP 95-10110
The ability of a Trichoderma sp. to produce volatile organic compounds (VOCs) over a four week period of growth was examined and the inhibitory effect of these volatiles against four selected basidiomycetes over the same period was assessed. After trapping, on tubes filled with chromatography packing material, VOCs were analysed on an integrated automated thermal desorbtion mass spectrometer syste...
