“…Recent comparisons of basidiomycete genomes show that the borderline between white-rot and brown-rot fungi is not as strict as previously thought and many brown-rotters such as F. pinicola, P. placenta and G. trabeum do have laccase genes in their genomes (Riley et al, 2014). Laccase is produced by D. squalensis (Susla et al, 2007), P. rivulosus (Hakala et al, 2005), T. pubescens (Palmieri et al, 2000), F. pinicola (Gramss et al, 1999), P. placenta (Wei et al, 2010), P. pulmonarius (De Souza et al, 2004), P. radiata (Arora and Gill, 2001), P. abieticola (Koutrotsios and Zervakis, 2014), P. velutina (Boddy, 2000), A. praecox and P. ostreatus . Although the studied basidiomycetes P. pulmonarius, P. radiata, D. squalens, P. rivulosus, C. unicolor, P. abieticola, P. velutina, A. praecox, T. pubescens, P. ostreatus, F. pinicola and P. placenta produced laccase, they did not decolorize all studied dyes indicating that other enzymes than laccases were involved in decolorization of the tested dyes.…”

“…Studies have shown that L. edodes obtained higher mycelial growth at low pH (Furlan et al, 1997). Possibly the pH reduction contributed to the formation of aliphatic acids produced by white rot fungi in the fermentation (Hakala et al, 2005).…”

Lignocellulose is the most abundant environmental component and a renewable organic resource in soil. There are some filamentous fungi which developed the ability to break down and use cellulose, hemicellulose and lignin as an energy source. The objective of this research was to analyze the effect of three nitrogen resources (ammonium sulfate, saltpetre, soybean) in the holocellulolitic activity of Lentinula edodes EF 50 using as substrate sawdust E. benthamii. An experimental design mixture was applied with repetition in the central point consisting of seven treatments (T) of equal concentrations of nitrogen in ammonium sulfate, potassium nitrate and soybean. The enzymatic activity of avicelase, carboxymetilcellulase, β-glucosidase, xylanases and manganese peroxidase was determined. The humidity, pH, water activity (a w ) and qualitative analysis of mycelial growth in 8 times of cultivation were evaluated. The results showed negative effect on enzyme production in treatments with maximum concentration of ammonium sulfate and potassium nitrate. The treatments with cooked soybean flour expressed higher enzymatic activities in times of 3, 6 and 9 days of culture, except in the activity of manganese peroxidase. The highest production was observed in the treatment with ammonium sulfate, and soybean (83.86 UI.L -1 ) at 20 days of cultivation.

Effect of Physisporinus vitreus on wood properties of Norway spruce. Part 1: Aspects of delignification and surface hardness

et al. 2011

The white rot fungus Physisporinus vitreus is currently tested for several biotechnological applications such as permeability improvement of refractory wood species or the optimization of the acoustic properties of wood for violins. The enzymatic activity of P. vitreus results in the degradation of pit membranes and simultaneous alterations of the tracheid cell wall structure in wood of Norway spruce wPicea abies (L.) Karstx. By this means, selective delignification and simultaneous degradation occur in the latewood tracheids at short incubation times. To study the delignification of individual cell wall layers in latewood tracheids, cellular UVmicrospectrophotometry was applied to wood of Norway spruce that had been incubated for between 3 and 9 weeks. By means of this technique, the progressing delignification was demonstrated in the latewood tracheid secondary walls. Moreover, local delignification in close proximity to hyphal tunneling, cavities, and notches was evident. Additionally, the mechanical changes were measured (a) at the macroscopic level by Brinell hardness test and (b) at the cellular level by nanoindentation. Brinell hardness was significantly reduced with increasing incubation time which was attributed to the partial delignification. Unlike Brinell tests, results from nanoindentation tests did not show a clear effect of fungal activity because of the material heterogeneity and the high spatial resolution of this technique. The present study provides methodological approaches for the investigation of wood-fungus interactions and contributes to a better understanding of the characteristics of wood decay at the subcellular level caused by the white rot fungus P. vitreus. Moreover, it establishes the basis for a subsequent chemical analysis, for which the results will be the topic of a second paper in this series.
