Spalting Fungi : Genetic Identification, Material Interactions and Microscopical Characteristics of Extracted Pigments

Creator:: Vega Gutiérrez, Sarath Mercedes
Abstract:: 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...

Perceptions on Spalted Wood: The Influence of Historic Spalting Patterns and Valuation of Spalted Wood Around the World.

Creator:: Vega Gutiérrez, Patricia T.
Abstract:: 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...

Fungi-Derived Pigments for Sustainable Organic (Opto)Electronics

Creator:: Gieshers, Gregory, Van Schenck, Jonathan, Gutierrez, Sarath Vega, Robinson, Sara, and Ostroverkhova, Oksana
Abstract:: We present on the optical and electronic properties of a fungi-derived pigment xylindein for potential use in (opto)electronic applications. Optical absorption spectra in solutions of various concentrations and in film are compared and are consistent with aggregate formation in concentrated solutions and films. In order to improve film morphology obtained...

Wood-Rotting Fungal Pigments as Colorant Coatings on Oil-Based Textile Dyes: A Detailed View of the Interaction between Fungal Pigments and Some Commercial Fabrics

Creator:: Palomino Agurto, Mardonio
Abstract:: Natural dyes have been used to color textiles for centuries, but with the shift to mass production, the use of synthetic dyes has increased due to their lower cost and easy manufacturing volume. However, synthetic dyes (such as disperse blue dyes 106 and 124) have been reported to cause skin...

Optimizing Production of Xylindein by Chlorociboria sp. and its Potential for Use with Nanocellulose

Creator:: Van Court, R. C.
Abstract:: 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,...

Oils Colored with Wood-Staining Fungal Pigments : Color Loss, Oxidation, and Structural Breakdown

Creator:: Hinsch, Eric M.
Abstract:: 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...

Distribution of Chlorociboria species in riparian forests of Western Oregon

Creator:: Kramer, Olivia E.
Abstract:: 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...

Fabrication of Biological Pigment Nanowires by Inkjet Printing

Creator:: Cao, Yu
Abstract:: Digital inkjet printing is developing quickly today because inkjet printing processes consume less energy and water and produce less waste discharge than traditional dyeing and other printing technologies. Inkjet printing provides more versatility and flexibility in terms of printing patterns and colors. Natural pigments are gaining more attention today as...

Alternative Carrier Solvents for Use with Resolubilized Fungal Pigments to IncreaseInternal Color Coverage in Wood Substrates

Creator:: Pittis, Lauren
Abstract:: 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...

Phylogenetic Identification of Pathogenic and Endophytic Fungal Populations in West Coast Douglas-fir (Pseudotsuga menziesii) Foliage

Creator:: Daniels, Hazel A.
Abstract:: Douglas-fir provides social, economic, and ecological benefits in the Pacific Northwest (PNW). In addition to timber, forests support abundant plant and animal biodiversity and provide socioeconomic viability for many rural communities. Products derived from Douglas-fir account for approximately 17% of the U.S. lumber output with an estimated value of $1.9...
