Chelator production and cellobiose dehydrogenase activity of wood inhabiting fungi
2000 - IRG/WP 00-10363
Multiple components have been postulated to be involved in the Fenton-based biological degradation of wood by brown rot fungi. Chelators have been implicated in essential iron reduction steps. Cellobiose dehydrogenase activity and quinone reducing activity have also been implicated in brown rot biodegradation. When biochelator production by three white rot fungi, three brown rot fungi and three wo...

Use of mixed populations of microflora to control sapstain on radiata pine
2002 - IRG/WP 02-10427
Most methods of biological control in the wood products field have focused on the use of single species of fungi or bacteria to control sapstain or decay. The approach taken in this study involved applying soil microorganisms, in combination with nutrients and various adjuvants that collectively form the biological control system. Radiata pine branch discs, autoclaved or fresh, were dipped in ...

Effects of wood-inhabiting marine fungi on food selection, feeding intensity and reproduction of Limnoria tripunctata Menzies (Crustacea, Isop.)
1981 - IRG/WP 480
The paper gives a condensed survey on laboratory tests with Limnoria tripunctata Menzies and pure cultures of 9 different marine wood-inhabiting fungi. Limnoria is able to distinguish between fungus-infested and non-infested wood. Wood with dead mycelium mostly proved to be less attractive or even repellent and was initially consumed less than with living fungi. On non-infested wood, initial feedi...

Screening of fungal strains for wood extractive degradation
1998 - IRG/WP 98-10254
Fungal strains were screened for their ability to degrade apolar extractives in wood from scots pine. The degradation of total wood extractives by 91 different strains was monitored in stationary batch assays incubated for 6 weeks. The results obtained show that the ability of wood-inhabiting fungi to utilize wood extractives varied greatly, even for different isolates of the same species. Fungal ...

The effect of chitosan on the growth and physiology of two wood inhabiting fungi
2006 - IRG/WP 06-10590
The effect of chitosan on the wood inhabiting fungi Sphaeropsis sapinea and Trichoderma harzianum was evaluated at cellular level. Increasing concentrations of chitosan caused an increase in the amount of peroxide in cultures of S. sapinea, which was accompanied by a simultaneous decrease in superoxide. The same effect was not observed in T. harzianum. The growth of both fungi was inhibited when h...

Effect of fumigation with Sulfuryl Difluoride on wood inhabiting fungi, a laboratory test
2006 - IRG/WP 06-30410
Special methods are necessary for the control of wood destroying organisms in the preservation of monuments and historic buildings because of the conservation of their originality and uniqueness. The control of wood destroying organisms can be realized with conventional liquid wood preservatives or alternative methods. One of these methods is the fumigation. One fumigant, which was in the past of...

Molecular characterization and biodiversity of wood-decaying fungi in French Guiana
2014 - IRG/WP 14-10825
Fungi from tropical regions are currently under-represented in the classification system. Indeed, difficult access to tropical forests and irregular occurrence carpophores make it complicated to study fungus species in such environments, unlike in European zones where fungal diversity and taxonomy are better known. The purpose of this work was to enhance classification by integrating new data that...
