Effect of Cinnamomum kanehirae Extractives on the Compositions of the Fermentation Broth of Antrodia cinnamomea
2007 - IRG/WP 07-10632
The fruiting body of Antrodia cinnamomea, called niu-chang-chih, is well known and highly prized in Taiwan as a folk medicine. This fungus is endemic to Taiwan and the growth of which is restricted to the inner heartwood cavities of another endemic tree species, Cinnamomum kanehirae. The fungal basidiomes have been used for treating food and drug poisoning, diarrhea, abdominal pain, hypertension, ...

Wood decay fungi from New Zealand leaky buildings – PCR identification (Part 2) and aerial spore trapping
2008 - IRG/WP 08-10649
Prior to this study, it was not know which species of decay fungi caused decay in New Zealand leaky buildings. Use of molecular biology methodology, polymerase chain reaction (PCR), and subsequent DNA sequencing, as well as classical mycological techniques based on morphology, has enabled identification of decay fungi and has provided insight into their relative importance based on isolation frequ...

Antifungal activity of essential oils against common wood degrading/decaying fungi
2008 - IRG/WP 08-30465
Despite the wide use of essential oils in pharmaceutical and food industry as antimicrobial agents, their use as wood preservatives has not been fully explored. In this study, 12 essential oils were screened in nutrient medium for their antifungal activity against 8 common mould, sapstain or decay fungi. Subsequently, one essential oil, eugenol was evaluated for decay resistance in an agar/wood ...

A rapid microscale assay for determining growth of wood inhabiting fungi against Lactobacillus metabolites
2009 - IRG/WP 09-20412
Lactobacillus sp. are well known for their ability to produce secondary metabolites with potent inhibitory activity against a wide range of bacterial species and there is increasing evidence to support their antifungal activity. These metabolites are often screened in laboratories using microscale 96-well plate optical density assays. The objective of this study was to develop an optical density a...

A genomic sequencing approach to study wood decay and copper tolerance in the brown rot fungus, Antrodia radiculosa
2010 - IRG/WP 10-10720
We used Illumina paired-end short read sequencing (76 nt, 300 bp insert size) to produce a de novo assembly of the genome of Antrodia radiculosa, a copper-tolerant brown rot fungus that is capable of aggressive wood decay. Quality analysis of the base calls in the dataset (8.95 Gb) showed that the majority of the nucleotide sequence was of the highest quality with 5% in the lowest quality group. ...

Gene expression analysis of a copper-tolerant brown rot fungus on MCQ-treated wood
2011 - IRG/WP 11-10748
Most brown rot fungi are copper-tolerant, which makes them difficult to control with copper-based wood preservatives like MCQ. To better understand what biological processes are regulated, we used our model species, Antrodia radiculosa, to examine expression of genes on MCQ-treated wood. Our hypothesis was genes that decreased copper bioavailability would be up-regulated early, when wood showed ...

Analyses of premature failure of utility poles
2012 - IRG/WP 12-40584
In this study a total number of 18 utility poles of Scots pine (Pinus sylvestris) impregnated with a copper-chromium containing preservative were investigated. They were part of different lower voltage transmission lines in the western part of Germany and failed before predicted minimum service life. All poles in this study were less than 15 years in use. The type of decay and fungi were evaluated...
