Serpula himantioides is a wood-decaying fungal pathogen which widespread and causes potentially serious butt rot in living trees of numerous coniferous plantation species. This study aimed to quantify S. the wood Sawara cypress (Chamaecyparis pisifera) with using real-time polymerase chain reaction (real-time PCR). Species–specific primers were designed for internal transcribed spacer 2 (ITS2) ...

The impacts of white-rot fungi on altering wood chemistry have been studied mostly in vitro. However, in vivo approaches may enable better assessment of the nature of interactions between saprotrophic fungi and host tree in nature. Hence, decayed and sound wood samples were collected from a naturally infected tree (Carpinus betulus L.). Fruiting bodies of the white rot fungus Trametes versicolo...

Five lignans (secoisolariciresinol, pinoresinol, eudesmin, lariciresinol, and lariciresinol-4-methyl ether) were isolated from an MeOH extract from Araucaria araucana (Mol.) K. Koch wood for the first time in this species and their structures determined with spectroscopic methods. The antimicrobial activities of these compounds were determined for the bacteria Citrobacter sp., Bacillus subtilis...

Polysaccharopeptides (PSPs) are among the main bioactive constituents of Trametes versicolor (T. versicolor). The purpose of this research was to investigate the antioxidant activities of enzymatic hydrolysates obtained from T. versicolor polysaccharopeptides by 80 U/mL β-1,3-glucanase (PSPs-EH80). The half-inhibitory concentration (IC50) of PSPs-EH80 in metal chelating assay, ABTS and DPPH rad...

Chitosan multiple addition strategy was developed to improve laccase production from Trametes versicolor cultures. The optimized multiple addition strategy was carried out by two-time addition of 0.1 g L(-1) chitosan to a 2-day-old culture media, with 24-h interval between the treatments. Under these conditions, laccase activity of 644.9 U l(-1) was achieved on the seventh day and laccase produ...

polybrominated diphenyl ethers (pbde) are widely employed as flame retardants and constitutea group of emerging pollutants of high persistence. the degradation of different pbde commercial mixtures(penta-, octa- and deca-bde) by the white-rot fungus trametes versicolor under aerobic conditions wasstudied. this work demonstrates the capacity of t. versicolor to degrade three different pbde comme...
