Resistance of fungal derived pigments to ultraviolet light exposure
2014 - IRG/WP 14-30642
The potential for using fungal derived pigments as surface treatments for limiting photodegradation of wood was investigated. Extracts from Chlorociboria aeruginosa and Scytalidium cuboideum were compared with a traditional aniline dye and chromic acid treatment. Hybrid poplar sapwood samples treated with these solutions were exposed to 86.4 kj/m2 of UV radiation and assessed for lignin degradatio...

Potential Use of the Pigment from Scytalidium cuboideum and Chlorociboria aeruginosa as an UV-light Protection Additive in Oil Finishes
2019 - IRG/WP 19-40868
UV-light degradation of wood is one of the top reasons for consumer replacement of outdoor wooden structures. This type of degradation is seldom mechanical, and is instead often motivated by loss of aesthetics (graying). There are numerous commercial products available on the market that deal with this loss of color, many of which contain added pigments to ‘rejuvenate’ or ‘revitalize’ grey...

Bacterial staining of samba (Triplochiton scleroxylon)
1988 - IRG/WP 1362
Red- and green-stained areas on Samba wood have been tested by IR, X-ray and Neutron Activation Multielement Analysis. No difference could be seen between stained and unstained areas. The red- and green-staining seem to be related to the bacteria Pseudomonas aeruginosa which were isolated from both red- and green-stained areas on the wood surfaces....

Bacterial adhesion to selected wood finishes
2017 - IRG/WP 17-40793
A new generation of furniture, including antibacterial surfaces, should adjust to the changing needs of an ageing population. Respectively, determination of bacterial adhesion on wooden surfaces, finished with various wood finishes or coating is an important topic. The main aims of our work were of a preliminary character. We wanted to state if the existing methods for testing of bacterial adhesio...

Green Coloration of Wood in the Forest and Laboratory by Chlorociboria spp. – Applications for Furniture
2019 - IRG/WP 19-10947
Discoloration of wood caused by living saprophytic fungi is commonly found on lumber. These fungi do not destroy the integrity of wood, but the discolorations they cause are often considered undesirable. In Tunbrigde Wells (Great Britain), seldomly found green colored wood, usually considered commercially irrelevant, was valued for use in restoration of wood inlay artwork.
