Biodegradation of Different Genotypes of Miscanthus by Wood Rot Fungi
Miscanthus, which is comprised of several different genotypes, is an important high-biomass crop with applications in the biofuel industry and in the formation of biocomposite materials. The overall composition of Miscanthus can be altered via degradation with wood rot fungi. The starting composition revealed that the cellulose content of Miscanthus x giganteus was higher than that in Miscanthu...
متن کاملLong-term soil accumulation of chromium, copper, and arsenic adjacent to preservative-treated wood.
Chromated copper arsenate (CCA) treated wood has been used extensively in outdoor applications, ranging from fence posts to decking and wood foundations. CCA treatment provides long-term protection for wood because chemical reactions that take place during treatment fix the preservative elements in the wood. However, varying amounts of CCA have been reported to leach from the wood (Lebow 1996)....
متن کاملPreservative leaching from weathered CCA-treated wood.
Disposal of discarded chromated copper arsenate (CCA)-treated wood in landfills raises concerns with respect to leaching of preservative compounds. When unweathered CCA-treated wood is leached using the toxicity characteristic leaching procedure (TCLP), arsenic concentrations exceed the toxicity characteristic (TC) limit of 5mg/L in most cases. The majority of discarded CCA-treated wood, howeve...
متن کاملPilot-plant production of protease by Alternaria tenuissima.
Agar slants of a selected Alternaria tenuissima strain were illuminated to give conidia suitable for further propagation. For production of protease with an optimal caseolytic activity in the region of pH 8 to 10, the fungus was cultivated in steel fermentors with 6- and 60-liter working capacity. Maximal activity, 1.5 enzyme units per liter, was attained in a medium based on liver after about ...
متن کاملBacterial Biodegradation of CCA-Treated Waste Wood
As wood treated with chromated copper arsenate (CCA) is removed from service, methods for eliminating toxic metals from the wood are needed. CCA-tolerant bacteria were evaluated for their ability to modify CCA-treated wood. Aerobic bacteria were isolated from a 20-year-old test plot of CCA-treated stakes. Bacteria selected for their ability to grow on nutrient agar containing CCA components, we...
