Five solvents were used to resolubilize the fungal pigments of Chlorociboria aeruginosa and Scytalidium cuboideum, two common fungi used in the spalting of wood pieces. These solvents were tested as a replacement for dichloromethane in the pigment application process, via analysis of their ability to increase internal color coverage inside...

Abstract: Five solvents were used to resolubilize the fungal pigments of
Transects were run at five locations in the Benton County area searching for
samples of Chlorociboria spp. on dead wood, with fifteen total samples found. Of
these samples, eight samples had the wood species identified, with the majority found
on Acer macrophyllum and one on Salix spp. The density of...
Spalting fungi show strong potential as natural colorants on a variety of materials, specifically textiles and wood. Four species of spalting fungi are currently utilized in this manner: Scytalidium cuboideum, which produces a red pigment called draconin red, Scytalidium ganodermophthorum, that produces an unknown yellow pigment, and Chlorociboria aeruginosa and...
With the resurgence in the interest of using natural textile dyes, a solution must be found that will overcome the limitations of traditional natural dyes. This solution must also be safer for both humankind and the environment than are synthetic dyes. This study compares the colorfastness of commercially available synthetic...
Commercial methodologies for producing fungal pigments are of worldwide interest due to the desire to move away from synthetic dyes. Chlorociboria species and Scytalidium species have been reported to produce sufficient yields of pigments for commercial production and have attracted special attention because of their use in spalted wood applications....
Phytophthora ramorum is a plant pathogen that was accidentally introduced to the United States. This invasive microorganism has killed over a million trees in California and Oregon, and continues to spread to new areas. Diseased areas have been nationally quarantined to prevent further spread and more than ninety countries include...
School forests in South Korea are trees and vegetation areas within schoolyards, and they provide natural environments for schools and neighborhoods. After the Korea Forest Service (KFS) and local governments create these school forests, the management of school forests transfers to the host schools. Some studies suggest that experiences with...
Fungi from the genus Chlorociboria are known for their production of the blue-green quinonic pigment xylindein. Extracted xylindein has been the subject of investigations ranging from fabric dying to use a coloring agent in paint, and shows potential as an organic semiconductor in organic photovoltaics (OPVs) and other technologies. However,...
During the 1400s – 1600s, spalted wood was an expensive commodity used in marquetry style artworks across primarily Germany and Italy. It fell out of favor during the Industrial Revolution, but is currently experiencing resurgence in popularity with US woodturners. How spalted wood is used, and what types of spalted...
Wood-staining fungal pigments have potential uses as colorants for wood and textiles. Traditionally, organic solvents have been used as carriers for these pigments. However, other environmentally-friendly and more readily available carriers must be found. Natural oils have the potential to carry these pigments but have demonstrated color loss over relatively...

With the rapid development of new computer mediated technologies, instructors have more options of the modalities of responding to student writing. Whereas traditionally, responses have been written by hand, technological developments allow responses to take very different forms. Some of these technologies, such as word processing, mimic the text-on-page techniques...
Forest growth and yield models are critical to supporting decision making in forestry, but often lack considerations for wood properties. The feasibility of simulating wood properties in the context of a Douglas-fir individual tree growth and yield model was evaluated. This assessment explored the effect of predicted sapwood width, stem...
This manual provides guidance on creating subject heading proposals for Indigenous topics that can be submitted to the Subject Authority Cooperative Program (SACO) for addition to the Library of Congress Subject Headings.
The purpose of this.investigation was to determine how enzymes and oxygen influence the role ascorbic acid has on pigment degradation and browning during storage for strawberry juice and concentrate.
The ascorbic and dehydroascorbic acid content of blanched and unblanched, nitrogen-treated and air-exposed samples of strawberry juice and concentrate was measured...
