In this paper, the material from experimental provenance plot in Poland (Rogów) was presented. The tested trees were grown at the same time, in the same soil for the same period of time, but the parental stands of tested trees were from the different Polish regions. Based on the results it was concluded that origin of parental trees has an influence on the amount of juvenile wood expressed by the number of annual growth rings, as well as the volume occupied in the trunk of the trees. The wood formation, particularly the amount of juvenile wood, is influenced by the climatic conditions of parental trees’ habitat (epigenetic indicators). The amount of precipitation is predominantly important in this respect. The new mathematical model for estimating the number of annual increments corresponding to the juvenile wood zone was proposed.

This identification is crucial for regulatory purposes, certifying legal lumber, preventing environmental crimes, and protecting ecosystems and society. Current wood identification methods are primarily based on anatomical observation of wood tissues, chemical profiling using direct analysis in real-time time-of-flight mass spectrometry (DART-TOFMS), and DNA-based analyses. While these approaches have their advantages, they also present challenges, particularly when species-level identification is required for enforcement. As an alternative, metabolite profiling using separation techniques coupled with mass spectrometry shows potential as a robust species-level wood identification method. Here, we present a method for classifying wood at the species level through chemical profiling of the wood metabolome using comprehensive two-dimensional gas chromatography coupled to time-of-flight mass spectrometry (GC×GC-TOFMS) combined with chemometric analysis. In this study, different tissues, including sapwood, heartwood, and branches from seven wood species collected from genetically characterized trees representing three distinct genera (<i>Quercus</i>, <i>Acer</i>, <i>Picea</i>) were investigated. Principal component analysis (PCA) was used to visualize differences between species and tissue types, while partial least squares-discriminant analysis (PLS-DA) and feature selection were used to construct classification models for species-level wood identification.

Each classification model was tested with an external validation set, and the performance of the classification model was evaluated based on the prediction of the external validation data.

Length, width, and thickness of particles from the 2–4 mm and 4–10 mm fractions were then characterized, and the slenderness ratio and specific surface area calculated.

The results demonstrated there was little effect of size fractions on the slenderness ratio and specific surface area. However, the wood composite type did impact slenderness ratio and specific surface area, with OSB particles being characterized by the largest slenderness ratio and specific surface area. As expected from their slenderness ratio, but contradictory to their high specific surface area values, OSB particles were characterized by a high compatibility factor. But so were the PLY and ACQ PLY particles, which was unexpected based on their slenderness ratio. Of all hydration curves, only PB particles did not have a second temperature peak and preliminary cement-bonded boards made with PB particles were very brittle.

In this work, we consider a simplified bacterial decay model and develop a numerical framework to integrate the decay model into a standard DOL model. Two approaches are proposed and compared: one considering the homogenised effect of bacterial decay over the entire cross section, and the other taking into account the localised failure accelerated by bacterial decay and applying stiffness reduction to allow stress redistribution.

Among prokaryotes, the genus <i>Streptomyces</i> stands out, with laccases playing a key role in its lignocellulolytic enzyme system.

Prominent examples of intermediates are hydroxyl radicals. In <i>Basidiomycota</i> fungi, the production of these radicals occurs through quinone redox cycling, involving a Fenton reaction. This study demonstrates, for the first time, extracellular hydroxyl radical production via quinone redox cycling in the bacterium <i>Streptomyces cyaneus</i> CECT 3335, with laccase playing an essential role.
