Antagonistic effects of a range of fungi to Serpula lacrymans
1996 - IRG/WP 96-10156
Certain fungi have been demonstrated to exhibit antagonism towards Serpula lacrymans in culture. Species from the genera Trichoderma, Gliocladium, Penicillium and Hypomyces were among those exhibiting the strongest antagonism. Certain species showed antagonism in a range of media of varying nutritional status. The possible role of antagonistic fungi as biocontrol agents for Serpula lacrymans is di...

Antagonistic effect of some mycorrhiza fungi as biological control of blue-stain
1987 - IRG/WP 1314
This report discussed the possibility of using some mycorrhiza fungi as biological control of blue-stain. The results show that new bio-technological possibilities are opening, because, by cultivating antibiosis fungi in fermentor, it is possible to prepare extracts which can then be used as the natural preservative to control the blue-stain in wood....

Effect of media composition on the antagonistic properties of Trichoderma spp. against wood decay fung
1992 - IRG/WP 92-1538
Most screening of potential biocontrol agents of wood decay fungi has previously been undertaken using artificial media. Similarly experiments designed to evaluate the mechanisms involved in antagonism between biological control agents and target fungi, have largely been carried out in conditions which do not accurately reflect the nutrient status of wood. This paper examines the influence of nutr...

Antagonism to spore germination in Scots pine
1990 - IRG/WP 1458
Germination of Lenzites trabea and Chaetomium globosum spores was observed directly on wood blocks, on water soluble extracts and on organic solvent soluble extracts from pine wood. In all cases pine heartwood was found to be antagonistic to spore germination but pine sapwood varied in its antagonism according to the method of drying. Chromatography revealed that extracts from antagonistic wood di...

Bacteria as possible organisms for biological control of blue stain
1988 - IRG/WP 1339
The article discusses the possibilities of biological control of blue stain. Besides using some antagonistic fungi, the possibility of using antagonistic bacteria, which offer still greater possibilities, should not be overlooked. Tests performed have shown that some bacteria from the genera Streptomyces and Pseudomonas have a strong antagonistic effect of blue stain....

Susceptibility of Lentinus lepideus (Fr.:Fr.) Fr. to volatiles produced by Trichoderma spp
1987 - IRG/WP 1316
A range of Trichoderma species and strains were tested for their ability to produce fungistatic volatiles. Volatiles from all isolates produced fungistatic effects on Lentinus lepideus however wide interspecies and interstrain variability in the level of response was evident. Cross plating studies between the Trichoderma isolates and Lentinus lepideus showed that Lentinus lepideus was overgrown an...

Laboratory studies on the antagonistic properties of Scytalidium spp to Basidiomycetes with regard to biological control
1981 - IRG/WP 1130
This investigation was initiated to study the progress of the antagonism against various opposing species of basidiomycetes. The action of the FY strain of the Scytalidium spp isolated by Ricard and Bollen (1968) was compared with that of new isolates of Scytalidium spp against isolates of wood decaying fungi from British sites, specifically Lentinus lepideus the most common basidiomycete causing ...

Control of sapwood-inhabiting fungi by fractionated extracellular metabolites from Coniophora puteana
1991 - IRG/WP 1494
The objective of this study was to test the fractionated metabolites released by Coniophora puteana for their antagonistic activity against the sapstain fungi Ceratocystis coerulescens and Aureobasidum pullulans, and the molds Asperigillus niger and Penicillium spp. The acetone-soluble fraction obtained from the culture filtrate prepared from Coniophora puteana grown on 6% malt extract agar inhibi...

A bibliography of the dry rot fungus, Serpula lacrymans
1988 - IRG/WP 1337
For many decades the occurrence of dry rot in buildings has been the cause of serious concern in temperate regions of the world. Consequently, much effort has concentrated on determining the morphology of dry rot and on finding means of prevention and control. During early studies, observers tried to understand the phenomenon of dry rot as a whole, and in the course of the 19th century aspects cha...

Biological control of decay
1975 - IRG/WP 135
One approach to the biological control of decay in standing poles, live trees or seedlings is with microbial immunising commensals or IC.┬ĚThese are microorganisms able to grow in the wood without damaging it and as a result of such growth to protect against certain types of decay. Scytalidium and Trichoderma spp have been tested in the field. The latter species have shown an establishment rate in...

Screening of bacteria, yeasts and Trichoderma isolates for antagonism toward stain and mould fungi on agar media and wood
1999 - IRG/WP 99-20159
A screening programme of soil bacteria for antagonism toward mould and wood stain fungi was undertaken on 8 types of agar-based media by application of several bacteria to each plate. The rapid screening method was subsequently verified by testing antagonism of the most promising bacteria on Scots pine sapwood. Most of the 64 bacterial showed antagonistic effects on certain media against individua...

Shorter-term biological control of wood decay in pre-seasoning pine roundwood as an alternative to chemical methods
1992 - IRG/WP 92-1555
Previous studies on the long-term control of decay in creosoted transmission poles, using Trichoderma and other antagonistic moulds, have met with limited success. However, it is possible biological control is more suited to control of decay on shorter time scales. An earlier study, focusing on pre-seasoning treatment of transmission poles showed that favourable porosity increases could be brought...

Antagonism of Scytalidium lignicola against wood decay fungi
1989 - IRG/WP 1392
Antagonistic abilities of Scytalidium lignicola against white- and brown-rot wood decay fungi were evaluated. Scytalidium lignicola did not produce inhibition zones but overgrew the decay fungi on a malt-agar medium and in most cases killed them. Pretreatment of Douglas-fir and Southern pine blocks with Scytalidium lignicola prevented decay. Blocks that were heated or treated with propylene oxide ...

Assessment of antagonism between lignicolous microorganisms: Research on possible use to preserve wood poles
2010 - IRG/WP 10-10718
Biological environments contain a certain number of microbial populations which, within a given ecological niche, display various relations ranging from symbiosis to parasitism. Researchers have been interested in these types of relations for around fifty years, especially in one very particular type of relationship: the antagonism exerted between individuals of the same microbial population. Toda...
