Ability of heartwood extractives to inhibit the growth of a bacterial symbiont of Teredo navalis
2000 - IRG/WP 00-10369
Shipworms are important destroyers of wood in the marine environment, and wood users have long sought methods for preventing or limiting their attack. While heavy -duty wood preservatives are highly effective against these organisms, there is increasing concern about risks to non-target organisms. This has resulted in a gradual shift away from broadly toxic materials to either alternative material...

Laboratory evaluation of anti-sapstain formulations
1989 - IRG/WP 3510
Four formulations were tested for their efficacy in controlling molds and sapstaining fungi on wood according to the Standard-II of Japan Wood Preserving Association (JWPA). Relative efficacy was compared on the basis of visual rating of the fungal growth on the treated and untreated wood surfaces when the wood specimens were exposed to each monoculture of 5 test fungi at 26±2°C and 70-80% for 4...

The bacterial transformation of organic biocides; a common mechanism?
2006 - IRG/WP 06-10585
It was found that a number of unformulated organic biocides showed a susceptibility to degradation by proteobacteria. Exposure of tebuconazole, a candidate biocide, chlorothalonil and IPBC to a Ralstonia strain was found to result in biocide detoxification, as demonstrated through HPLC and a bioassay. Exposure of the biocides to a previously identified extracellular factor was also found to resu...

Blue Staining of Coated Modified and Unmodified Wood
2006 - IRG/WP 06-10589
We investigated resistance of unmodified, DMDHEU modified and oil heat treated uncoated and coated Scots pine wood against blue stain fungi. Both EN 152-1 and the reverse exposure tests showed excellent resistance of DMDHEU and especially of oil heat treated wood against blue staining. It is not needed to add any additional protective coating layers to prevent modified wood from staining. However,...

2007 - IRG/WP 07-10613
Use of domestic and commercial woods of the Caspian Sea forest fringes and evaluation of their durability against marine destructive factors were investigated. The samples of species of elm (Zelkova carpinifolia), oak (Quercus castanifolia), beech (Fagus orientalis), Maple (Acer insgin), Alder (Alnus subcordata), and horn beech (Carpinus betulus) were impregnated with CCA (Chrome–Cupper-Arsenic)...

End Coating Masson Pine Grown in South China to Prevent the Development of Blue Stain
2007 - IRG/WP 07-30428
One end (randomly selected) of logs of mason pine (Pinus massoniana) were coated with a wax-type end coating called ANCHORSEAL® immediately after tree cutting. The logs were then stored in summer weather in Guangxi, China. During the storage, at week 1, 2, 3, 4, 6, 8 and 12, five logs of mason pine were sawn into lumber or veneer for the visual observation and measurement of blue stain at the coa...

Laboratory test of blue stain control by chemicals
2007 - IRG/WP 07-30430
8 chemicals and some mixtures against Botryodiplodia theobromae Pat., Fusarium verticillioides(Sacc.)Nirenberg, Trichoderma harzianum Rifai, Trichoderma viride Pers., and Penicillium purpurogenum Stoll were conducted in laboratory by inhibition zone in the paper. The results were shown that: CBZ and benomyl as well as copper oxine alone are much high efficacy for inhibiting most of the 5 fungi tha...

An Investigation on Use and Durability of Some Industrial and Domestic Woods of Iran against Destructive Factors in Caspian Sea
2008 - IRG/WP 08-10636
In this study the use of domestic and commercial woods of the Caspian Sea forest fringes and evaluation of their durability against marine destructive factors were investigated. The samples of elm (Zelkova carpinifolia), oak (Quercus castanifolia), beech (Fagus orientalis), Maple (Acer insgin), Alder (Alnus subcordata), and horn beech (Carpinus betulus) species were impregnated with CCA (Chrome–...

Stained wood: The identification of natural dyes and mordants in wooden works of art
2010 - IRG/WP 10-20434
On the basis of current knowledge only natural-colored wood species crafted to veneers were used for the decorative design of furniture and wooden interior in classical antiquity.First applications of artificially stained wood can be dated to the late Middle Ages. In the Renaissance wooden works of art were manufactured by using intarsia of natural-colored, fungus-stained and artificially stained ...

Micromorphological and chemical characteristics of waterlogged archaeological bamboos excavated from the Yellow Sea
2012 - IRG/WP 12-10785
Bamboos have widely used as documentation material in Far Eastern countries such China, Korea and Japan. In particular, bamboo slips as documentation material were extensively used even after the wide spread of paper in those countries. A large number of bamboo slips have been excavated from the shipwreck since 2009 in Korea. Understanding the cause of deterioration of ancient bamboos is crucial f...

A survey on Bio-Resistance of Oak and Elm in Caspian Sea Water
2012 - IRG/WP 12-20483
Logs of Oak (Quercus castanifolia) and Elm (Zelkova carpinifolia) have been cut to lumbers with dimensions of 300×100×30 mm. The oven dried samples have been impregnated with CCA (Chrome–Cupper-Arsenic). Treated and untreated (natural as a control) woods have been established for 3, 6, 9 and 12 months in Amirabad beach of Behshare under fishing environment. The observation results shows that i...

Surface moulds and staining fungi on acetylated wood – effect of increasing acetyl content
2013 - IRG/WP 13-10797
Wood used in outside applications is susceptible to weathering and photo degradation, which often leads to surface discoloration, loss of brightness and surface deterioration. Research has shown that acetylated wood is more resistant against brown rot, white rot and soft rot, and more dimensionally stable than untreated wood. However, acetylated wood seems still to be disfigured by surface moulds ...

Changes in bacterial gut community of Reticulitermes flavipes (Kollar) and Reticulitermes tibialis banks after feeding on termiticidal bait material
2014 - IRG/WP 14-10819
In this study, 454-pyrosequencing was used to evaluate the effect of two termiticidal baits, hexaflumuron and diflubenzuron, on the bacterial gut community in two Reticulitermes flavipes colonies and one Reticulitermes tibialis colony. Results showed two bacterial groups to be most abundant in the gut, the Bacteroidetes and Spirochaetes, both of which do not appear to be adversely affected by bait...

Identification of the key factors influencing development of the blue stain fungi
2016 - IRG/WP 16-10872
Service life of wood is more and more frequently affected by aesthetic requirements than functional ones. In order to elucidate various aspects of service life, model house with façade elements made of 22 materials was built on the field test site at Department of Wood Science and Technology in Ljubljana. Colour and fungal disfigurement is among other parameters monitored on this house. In parall...

Bacterial Degradation of Pentachlorophenol Indicated in Groundwater Undergoing Long Term In-Situ Remediation
2016 - IRG/WP 16-50318
Pentachlorophenol (PCP, Penta) is a worldwide soil and water contaminant. The pervasive use of PCP as a fungicide, herbicide, pesticide, and as preservative for wood products has led to its global distribution. It is a highly effective preventative measure for most invasive insects, bacteria, fungi, and molds, as well as an excellent wood protection treatment. This study examined a known PCP conta...

Analysis of hindgut bacterial phyla frequency and diversity in subterranean termites exposed to chitosan-treated wood
2017 - IRG/WP 17-10882
The termite hindgut contains a microbial community that symbiotically aids in digestion of lignocellulosic materials. For better understanding of the dynamics of the bacteria-termite relationship, a species survey of bacterial hindgut microbes in subterranean termites (Reticulitermes flavipes: Kollar) collected from Louisville, Mississippi was performed after exposure to chitosan-treated and contr...

Bacterial adhesion to selected wood finishes
2017 - IRG/WP 17-40793
A new generation of furniture, including antibacterial surfaces, should adjust to the changing needs of an ageing population. Respectively, determination of bacterial adhesion on wooden surfaces, finished with various wood finishes or coating is an important topic. The main aims of our work were of a preliminary character. We wanted to state if the existing methods for testing of bacterial adhesio...
