Fungal Species: Chlorociboria aeruginascens

Identification of a Biosynthetic Gene Cluster for the Production of the Blue-Green Pigment Xylindein by the Fungus Chlorociboria aeruginascens

Scientists discovered the genetic instructions that allow certain fungi to produce xylindein, a beautiful blue-green pigment found in stained wood. By analyzing fungal genomes and studying gene activity, they identified nine genes working together to create this valuable compound, which has uses in textiles and electronics. While attempts to produce xylindein in laboratory yeasts were unsuccessful, their work successfully produced a related pigment and opens new pathways for understanding xylindein production.

Chlorencoelia (Leotiomycetes, Helotiales, Cenangiaceae) in New Zealand

mycolabadmin

Researchers discovered that fungi previously thought to be just two species found in New Zealand are actually three distinct species. By examining the fungi’s DNA and microscopic features, scientists identified two species new to science: Chlorencoelia australis and Chlorencoelia northlandica, plus another species originally described from Tasmania. This research shows that many fungi species thought to be widespread are actually multiple different species that look similar but are genetically distinct.

Production of Natural Colorants by Liquid Fermentation with Chlorociboria aeruginascens and Laetiporus sulphureus and Prospective Applications

mycolabadmin

This research explores the production of natural dyes from fungi as an environmentally friendly alternative to synthetic dyes. Scientists successfully grew two different fungi in large bioreactors to produce a blue-green dye (xylindein) and an orange-yellow dye (laetiporic acid). These natural dyes were then successfully used to color wood and dye silk fabrics. Impacts on everyday life: • Provides safer, non-toxic alternatives to synthetic dyes for clothing and textiles • Offers environmentally friendly coloring options for wood products and furniture • Contributes to reducing chemical pollution from synthetic dye production • Enables sustainable production of unique colors not easily achieved with other natural dyes • Supports the development of more eco-friendly consumer products
