Synergized pyrethrins insecticide as a spot treatment option for West Indian drywood termites
2023 - IRG/WP 23-11004
Pyrethrin is a natural biopesticide with relatively low mammalian toxicity. Two identical products in Australia contain pyrethrin in liquid CO2-propelled aerosol, Pestigas from BOC international and SupaPy Supagas. In the current study, the toxicity of SupaPy was tested against West Indian drywood termite Cryptotermes brevis as an option for spot treatment of this pest. Termites were exposed to wo...

A novel cellulose-binding domain from the brown-rot fungus Gloeophyllum trabeum
2023 - IRG/WP 23-11019
Wood-rotting basidiomycetes are the major organisms decomposing wood in nature. They are classified into two groups based on their decay modes; white-rot fungi and brown-rot fungi. White-rot fungi secrete various cellulolytic enzymes during the wood degradation process. The enzymes are known to be often appended with a cellulose binding domain (CBD) which assists the activity of catalytic domain. ...

The cellulose binding mechanism of a novel cellulose binding domain from the brown-rot fungus Gloeophyllum trabeum
2023 - IRG/WP 23-11021
In nature, wood decay is caused by various wood-rotting basidiomycetes. Wood-rotting basidiomycete are mainly divided into white-rot fungi and brown-rot fungi. Their main carbon source is cellulose of the wood cell wall during wood decay, and they produce a variety of enzymes to decompose cellulose. The cellulolytic enzymes often possess a cellulose binding domain (CBD) as an additional domain con...

The appropriateness of central one-ninth or core retentions as a means of demonstrating penetration compliance
2023 - IRG/WP 23-40976
Treatment quality is in general terms dependent upon the preservative retention, and how the preservative is distributed throughout the cross-section of the treated article in question, i.e. the penetration of the preservative. Of these two fundamental qualities that are intrinsically linked to treatment quality, penetration is in general terms the most subjective. The determination of retention i...

Research on gaseous COS degradation by brown-rot fungus Gloeophyllum trabeum
2024 - IRG/WP 24-11033
Physiological studies of wood rotting fungi have mostly focused on the metabolism of carbon and nitrogen sources, which constitute the dominants components of wood. On the other hand, despite the physiological importance of trace elements such as sulfur, studies on their acquisition sources and metabolic pathways are limited. Until now, wood rotting fungi have been thought to utilize slight amount...

A novel cellulose-binding domain from the brown-rot fungus that can be used to evaluate cellulose in wood
2024 - IRG/WP 24-11046
Wood-rotting basidiomycetes are the primary microorganisms that decay wood in nature. They are classified as white-rot fungi and brown-rot fungi by the difference in decaying types. White-rot fungi secrete a variety of cellulolytic enzymes during wood degradation. These enzymes often have an additional cellulose-binding domain (CBD) that adsorbs to the cellulose surface and localizes the catalytic...

Enhancing UV resistance and decay resistance of wood by nanoparticle dispersed linseed oil nanoemulsion
2024 - IRG/WP 24-20706
Enhancing increasing demand for eco-friendly and cost-effective wood coatings and preservatives has led to the development of water-borne formulations and use of non-toxic and natural materials such as vegetable oils and waxes. The aim of this study was to improve the UV resistance and decay resistance of wood by nanomaterial dispersed linseed oil emulsions. Highly stable nanoemulsions of linseed ...
