Biobleaching of hardwood unbleached kraft pulp (UKP) by Phanerochaete chrysosporium and Trametes versicolor was studied in the solid-state fermentation system with different culture media. In this fermentation system with low-nitrogen and high-carbon culture medium, pulp brightness increased by 15 and 30 points after 5 days of treatment with T. versicolor and P. chrysosporium, respectively, and...

Lakkaz, moleküler oksijen kullanarak fenolik bileşikleri yükseltgeyen ve mantarlarda yaygınca bulunan bir enzimdir. Bu çalışmada, Stropharia aeruginosa, Trametes versicolor, Hypholoma fasciculare, Cantharellus cibarius, Clytocibe nebularis Amanita muscaria gibi mantar türlerinin lakkaz aktivitelerinin yanı sıra toplam protein miktarının belirlenmesi kıyaslanması amaçlanmaktadır. Sonuçlar değerl...

BACKGROUND Cost-effective production of industrially important enzymes is a key for their successful exploitation on industrial scale. Keeping in view the extensive industrial applications of lignin peroxidase (LiP), this study was performed to purify and characterize the LiP from an indigenous strain of Trametes versicolor IBL-04. Xerogel matrix enzyme immobilization technique was applied to i...

14C-labeled averufin, versiconal hemiacetal acetate, and versicolorin A were efficiently converted to sterigmatocystin by Aspergillus versicolor, thus providing experimental evidence that these anthraquinones are biosynthetic precursors of sterigmatocystin, a xanthone.

Effects of nano-clay on weight loss of wood-plastic composites (WPC) by five fungi were studied. Nanoclay particles of 20 to 50 nm size were applied at 2, 4, and 6% WPC of 0,90 g/cm3 density. The white-rot fungi Physisporinus vitreus, Pleurotus ostreatus and Trametes versicolor as well as the brown-rot species Antrodia vaillantii and Coniophora puteana were used. Mass loss tests were conducted ...

The observation of two distinct, well-defined oviposition areas in nests of the primitively eusocial wasp Polistes versicolor suggests the presence of multiple egg-layers and territorial behaviors. Electrophoretic analysis of enzyme loci in pupae from 35 colonies revealed an average observed heterozygosity of 0.10 and the existence of private polymorphisms, thereby indicating a low dispersion i...

Phrynocephalus przewalskii is one kind of lizards inhabiting inclusively in the desert that has controversial viewpoints on its phylogeny. Based on mitochondrial ND2 gene of 119 samples from 12 geographic populations, we analyzed the effects of environmental factors on the variation of genetic diversity, as well as its relationship to P. versicolor. The results showed that these populations clu...

There is a possibility for a role of biofilms in the pathogenesis and chronicity of atopic dermatitis, plaque psoriasis, Lyme disease and tinea versicolor. In atopic dermatitis, plaque psoriasis and Lyme disease, there is evidence to suggest that biofilm-mediated Toll-like-receptor 2 recruitment and activation of the MyD88 pathway is essential. There is also evidence to suggest involvement of t...
