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, ...

In vitro evaluation of an integrated approach using Trichoderma harzianum and chitosan for the control of sapstain
2008 - IRG/WP 08-10659
In vitro assays were undertaken to evaluate the control of two sapstain fungi, Leptographium procerum and Sphaeropsis sapinea by a combination of chitosan or chitosan oligomer (CODP-14) and a naturally mutated strain of Trichoderma harzianum. Spore germination and hyphal growth of the test fungi were assessed on media amended with chitosan or chitosan oligomer with and without T. harzianum using ...

Effect of amphiphilic antioxidant alkyl ammonium ascorbate on inhibition of fungal growth: Application to wood preservatives formulation
2008 - IRG/WP 08-30466
Amphiphilic surfactants were synthesized from ascorbic acid and different fatty amines and evaluated for formulation of wood preservation products. Characterization of physicochemical properties of the new compounds indicated classical behavior of cationic surfactants. Antioxidant properties, estimated using methyl linoleate oxidation inhibition method, were similar to that of ascorbic acid teste...

Laboratory test of some formulations against stain and mould fungi isolated from bamboo wood
2009 - IRG/WP 09-30508
To screen the effective anti-mould formulations, fungicides such as carbendazim, tebuconazole, fludioxonil, difenoconazole, prochloraz, benomyl and 8-hydroxy-quinoline copper (copper oxine) were selected to conduct the laboratory test of fungicidal activity by method of inhibition zone against Botryodiplodia theobromae Pat., Fusarium sp., Alternaria tenuis Nees., Penicillium purpurogenum Stoll, Tr...

Mould resistance of bamboo timber treated with tebuconazole-loaded micells
2012 - IRG/WP 12-30586
In this paper both anti-mould test through inhibition zone and mould resistance test on bamboo samples were carried out evaluate mould resistant effect of tebuconazole (TBA) loaded micells. Results showed that TBA loaded micells prepared with a ratio of TBA to PEG113-b-PCL28 50:25 had the best mould resistance, followed by micells prepared with a ratio of TBA to PEG113-b-PCL28 50:50. PEG113-b-PCL2...

Influence of a pulsed electric field on the growth of surface fungi
2013 - IRG/WP 13-10795
The colonization of mold and staining fungi are not only an aesthetical problem. Blue stain fungi are able to penetrate paint films. Maintenance of coatings on wood are time consuming and costly. A new approach uses a pulsed electric field (PLEOT) in order to protect wood against surface fungi. This technology is evaluated in non-sterile laboratory conditions on different coated and uncoated Scots...

Investigations on the durability of several Congo basin wood species
2015 - IRG/WP 15-10840
The sawdust of ten wood species was studied to assess their natural resistance to decay. The extractives and lignin contents were primarily determined (between 2.7-16.0% and 26.8-35.9% respectively) to give an overview of the chemical distribution. Then, a phytochemical screening (colorimetric methods) characterized the different chemical functional groups in all extracts studied. Antioxidant act...

Impregnation of wood with antifungal compounds from low-quality tree biomass
2022 - IRG/WP 22-30763
In this paper we have reviewed recent research on the development of bio-based preservative formulations for wood done at the Department of wood science and technology, Ljubljana. Preservative formulations used in this investigation were prepared using plant polyphenols as biocidal agents. These nonstructural components of wood were stilbenes and flavonoids, and were extracted from wood of broken ...

Hydrothermal liquefaction of spent mushroom substrate as a source of antifungals
2023 - IRG/WP 23-30791
The aim of this study was to characterize the chemical composition of hydrothermal liquefaction (HTL) products from the spent mushroom substrate (SMS) of Agaricus bisporus (Lange) Imbach and Pleurotus ostreatus (jacq.) P. kumm. using high-resolution 1H nuclear magnetic resonance (NMR), and assess the antifungal properties of these thermal decomposition liquids against wood decaying fungi (Coniopho...
