“…These findings indicate that the two Crustoderma isolates are CCAtolerant fungi. The difference in the extent of wood weight loss between the two isolates indicates that intraspecific variation exists in their ability to degrade wood, which is similar to the results of studies conducted to evaluate other copper tolerant species such as Wolfiporia cocos De Groot and Woodward 1999) and Antrodia vaillantii (Collet 1992). Considering that these two isolates of very good wood degraders originated from the CCA-treated wood wastes of two different tree species, screening of CCAtreated wood wastes from a variety of trees species would be useful for the detection of new Crustoderma sp.…”

“…These findings and the results of the present study suggest that the ability of fungi to decompose wood may differ among tree species (Table 3). As well, the biodegradability of the treated wood varies significantly with copper-based preservatives as shown in the previous studies on the isolates of the copper-tolerant fungus W. cocos De Groot and Woodward 1999).…”

In this study, basidiomycete isolates that possessed a strong ability to degrade chromated copper arsenate (CCA)-treated wood were characterized. These fungal isolates, which were collected from CCA-treated pine log wastes, showed no recognizable morphological properties on culture media. Nucleotide sequence analysis of the large subunit rDNA of the isolates revealed that they were one species. Based on the high sequence similarity (>95%) and close phylogenetic relationship with several known species of Crustoderma, the fungal isolates characterized in this study were classified as a Crustoderma sp. In a wood degradation test, Crustoderma isolate KUC8611 produced a remarkably higher weight loss in CCA-treated Pinus radiata (68.7%), Pseudotsuga menziesii (39.7%), and Tsuga heterophylla (38.5%) wood than other evaluated basidiomycete species, including Crustoderma flavescens and Crustoderma corneum. In addition, extracellular enzymes for cellulose and protein degradation were detected when the isolates were cultured in chromogenic media, which supports the finding that isolate KUC8611 is a wood degrader. Furthermore, an in vitro test for metal tolerance revealed that isolate KUC8611 showed strong arsenic tolerance, but that it could not tolerate copper. Finally, isolate KUC8611 produced lower amounts of oxalic acid than copper-tolerant fungi such as Fomitopsis palustris and Antrodia vaillantii. To the best of our knowledge, this is the first study to report the degradation of CCA-treated wood by a Crustoderma species.

“…This is in line with the observation of DeGroot et al 2000 andWoodward, 1999 that Douglas-fir stakes that did not meet standard retention requirement before being exposed to service test were more easily degraded by decay fungi and termites (Cryptotermes cavifrons Bank).…”

The effect of different chemical preservatives on service life of selected wood species was evaluated in a field plot at the Forestry research site, University of Uyo, Akwa Ibom, Nigeria. Three wood species, Triplochiton scleroxylon K. Schum (Obeche), Gmelina arborea Linn (Gmelina) and Terminalia ivorensis A Chew (IdigboBlack afara) were used for this study. Two chemical preservatives namely; acid copper chromate and copper citrate at concentrations of 0%, 0.37%, 0.75% and 1.5% each and a mixture of the two preservatives (mixed preservative) at the given concentrations were used in treating stakes of these wood species and their retentions determined. Service life of the stakes was evaluated at the end of six months and insect pest and fungi that infected them identified. The result indicated that obeche had the highest mean retention of 4.04 kg/m 3 .The result also showed that the retention increased with increase preservative concentration, the highest retention of 6.80 kg/m 3 was obtained with mixed preservative at 1.5% concentration. Treated stakes of all the three wood species lasted for the six months of the experiment while the untreated stakes failed within the period. Highest service life rating of 10 (no termite (Cryptotermes cavifrons Bank) damage) and (-) (no fungal growth) was obtained with mixed preservatives at 1.5% concentration. Based on these findings the use of these preservatives at concentrations of 0.075%-1.5% to enhance service life is recommended.

“…Copper is an essential micro-nutrient for most living organisms, and copper requirements by microorganisms are usually satisfied by very low concentrations of the metal, in order of 1-10 µM. However, copper present in higher concentration is extremely toxic to microbial cells (Labbé and Thiele 1997), although some copper-tolerant fungi had already been described (De Groot and Woodward 1999). The results suggested that in solid-state cultures, P. pulmonarius presented high resistance to copper.…”
