“…During the three-year storage period, the total content of phenolic acids in the residues decreased by 76%. This effect can also be attributed to the significant activity of fungi commonly found in the forest environments such as white-rot fungi, brown-rot fungi, ectomycorrhizal fungi and ericoid mycorrhizal fungi, which show the ability to degrade the phenolic compounds [75][76][77].…”

A significant amount of logging residue is produced during roundwood harvesting. Logs are often left in forest sites due to, for example, ecological or logistical aspects. Taking into account the fact that the number of studies focused on changes in the properties of the residue is very low, it was decided to conduct research on the effect of a three-year storage period in forest stands on the chemical properties and energy potential of the wood. The research design allowed for the determination of changes during up to three years of storage. The performed analysis showed a highly negative impact on the characteristics of the material. These adverse effects were probably caused by the activity of microorganisms such as fungi and bacteria, as evidenced by the increased concentrations of ergosterol and low-molecular-weight organic acids. Moreover, it was found that wood stored for three years was characterized by a lower cellulose content; an increased percentage of lignin; a reduced content of sterols (desmosterol, stigmasterol, lanosterol and β-sitosterol) and phenolic acids; and reduced antioxidant activity, as determined with the ABTS+ method. Storing logs also led to a reduction in the energy potential of the residues, as shown by a reduction in net and gross calorific value and an increased ash content.

“…A genus of wood rotters known as "white rot fungus" emits extracellular enzymes, primarily lignin peroxidase, manganese peroxidase, and laccase, which breaks down lignin and due to this potential it can be utilised as an excellent resource that can be used in the bioremediation of pollutants (6) .…”

Objectives: To investigate the antibacterial activity and photo-catalytic efficacy of CuNPs synthesized from Lentinus squarrosulus used for the degradation of commercial textile dyes. Methods: The Copper nanoparticles (CuNPs) were biosynthesized using L. squarrosulus, a new fungal isolate from the dead trunk of N. odorum. The production of copper nanoparticles using mycoextract was simple and environmentally friendly, yielding stable copper nanoparticles in a variety of shapes. Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), and EDAX analysis have all been used to establish that CuNPs were successfully formed. Findings: The research findings of the present study show that absorption spectra around 300 to 350 nm in UV-vis spectra followed by the presence of FT-IR peaks at 3680cm −1 and 3856.7cm −1 of proteins, carbohydrates, flavonoids, and tannins confirmed the myco-synthesis of copper nanoparticles using L. squarrosulus. Additionally, scanning electron microscopy examination of their external morphology reveals the existence of CuNPs with an average particle size of about 200 nm each, which are the primary spherical nanoparticles. Energy-dispersive x-ray (EDX) analysis was performed to further investigate the configuration of copper nanoparticles and it was found that, pure copper (03.51 percent) was present in CuNPs. The produced CuNPs were assessed for their antimicrobial activity and the results show that they were highly effective against Enterobacter aerogenes MTCC 2823 and Streptococcus mutans MTCC 497, while Escherichia coli MTCC 739 and Enterococcus faecalis MTCC 439 showed moderate antibacterial activity. Further, the photocatalytic dye degradation potentials of myco-synthesized CuNPs showed higher degradation efficiency in fast green dye, moderate degradation rate in Congo red dye and a very low degradation rate in the brilliant blue dye.

Introduction: Silver fir (Abies alba Mill.) is one of the most valuable conifer wood species in Europe. Among the main opportunistic pathogens that cause root and butt rot on silver fir are Armillaria ostoyae and Heterobasidion abietinum. Due to the different enzymatic pools of these wood-decay fungi, different strategies in metabolizing the phenols were available.Objective: This work explores the changes in phenolic compounds during silver fir wood degradation.Methodology: Phenols were analyzed before and after fungus inoculation in silver fir macerated wood after 2, 4 and 6 months. All samples were analyzed using high-performance liquid chromatography coupled to a hybrid quadrupole-orbitrap mass spectrometer.Results: Thirteen compounds, including simple phenols, alkylphenyl alcohols, hydroxybenzoketones, hydroxycinnamaldehydes, hydroxybenzaldehydes, hydroxyphenylacetic acids, hydroxycinnamic acids, hydroxybenzoic acids and hydroxycoumarins, were detected. Pyrocatechol, coniferyl alcohol, acetovanillone, vanillin, benzoic acid, 4-hydroxybenzoic acid and vanillic acid contents decreased during the degradation process. Methyl vanillate, ferulic acid and p-coumaric were initially produced and then degraded. Scopoletin was accumulated. Pyrocatechol, acetovanillone and methyl vanillate were found for the first time in both degrading and non-degrading wood of silver fir.Conclusions: Despite differences in the enzymatic pool, both fungi caused a significant decrease in the amounts of phenolic compounds with the accumulation of the only scopoletin. Principal component analysis revealed an initial differentiation between the degradation activity of the two fungal species during degradation, but similar phenolic contents at the end of wood degradation.
