Using DNA probes to characterize the metabolic pathway of pigment production in several wood-staining fungi
1996 - IRG/WP 96-10146
During shipment and storage, lumber is susceptible to sapstain, a wood discoloration caused by fungi. Currently kiln drying and chemical applications are used to control sapstain. However, the chemicals used to protect wood have a broad range of action, and so can affect other organisms. In addition, in Canada most of these chemicals are under temporary registration. Thus there is a need to develo...

Integrated protection of freshly sawn lumber using Bacillus subtilis and selected fungicide
1997 - IRG/WP 97-10235
Bioprotection against stain fungi has tremendous potential for reducing discoloration of freshly sawn wood while decreasing chemical consumption. Unfortunately, most bioprotectants appear to be unable to consistently perform under the array of conditions to which freshly sawn wood is exposed. While research is underway to understand the nature of the inconsistent performance, a more pragmatic appr...

Utilisation of carbohydrates by stain fungi in agar culture
1998 - IRG/WP 98-10248
Stain fungi are often defined by their ability to utilise the starch and free sugars found in ray parenchyma cells, and their inability to utilise other wood constituents. However, several species of stain fungi produce bore holes in wood cell walls. This suggests that enzymatic activity capable of degrading structural polysaccharides and/or lignin is associated with the growth of the appressorium...

Wood decay of Pinus sylvestris L. by marine fungi
1990 - IRG/WP 1463
Waterlogged wood decay by marine microorganisms represents a major problem for the conservation of wood structures of historic value. It is important to know which kind of decay affects the wood from a conservation point of view. Enzyme activities of 14 marine fungi belonging to several localities were studied. Also, the weight loss and the rot type suffered by the wood at a microscopic level were...

Comparison of culturable fungi found on two types of modified wood cladding
2023 - IRG/WP 23-11025
Modified woods are rapidly gaining popularity in the United States and are appearing on more public buildings. Because these are biocide-free products, they can support the growth of non-wood degrading fungi on their surfaces, many of which produce dark pigments and deface the cladding. Even growth of dark pigmented fungi on modified woods yields an even grey-black color, giving the materials a we...
