Summary: In this study, it was found that the brown-rot fungus can cause decay in Japanese cedar under both bright and dark conditions. The presence of mycelia inside the wood was observed even after 1 week of fungal exposure. Additionally, holes were seen in the torus after fungal exposure. It was also discovered that pectin decomposition occurs before holocellulose decomposition.

Summary: This study investigated the degradation of heat-treated wood by brown rot fungi and found that the decay increased the hygroscopicity of wood in the decaying state. Furthermore, it was observed that heat-treated samples were more susceptible to fungal decay compared to untreated samples, which may be related to the increase in moisture content.

Summary: This study investigated the bacterial decay process in compression wood (CW) tracheids of waterlogged archaeological wood (WAW) using various microscopy techniques. Erosion bacteria were identified as the primary degraders, and the extent of cell wall degradation varied depending on the severity of CW tracheids. Mild CW tracheids showed preferential decay in the inner S-2 layer, while severe CW tracheids exhibited gradual degradation of the cell wall from the exposed faces. The degradation was more extensive in mild CW tracheids, and the highly lignified outer S-2 layer was only degraded in mild CW tracheids.

Summary: Carbohydrate-based fatty acid esters (CFA esters) are non-toxic and environmentally friendly compounds that are used as antimicrobials and synthetic intermediates. They have applications in various industries, including food, surfactant, and pharmaceutical. In this study, different CFA esters were synthesized from methyl alpha-D-glucopyranoside and tested for their decay resistance properties against white-rot and brown-rot fungi. The results showed that most of these CFA esters protected the wood from fungal attack and reduced deterioration.

Summary: This study investigated the biodegradation abilities of different fungi on Dendrocalamus sinicus and studied the changes in chemical characteristics of the bamboo. The results showed that white-rot fungi T. versicolor selectively degraded the bamboo, while brown-rot fungi G. trabeum and R. placenta mainly attacked it during the middle stage. These findings have important implications for the bioconversion of Dendrocalamus sinicus.

Summary: This study investigates the relationship between extractive degradation and heartwood decay in Scots pine. The results show that the heartwood has substantial decay resistance against one type of brown rot fungi but little resistance against another. Extracts from decayed heartwood samples reveal extensive degradation of stilbenes by one type of fungi and a noticeable but insignificant loss of resin acids. The study highlights the importance of extractive degradation in heartwood decay and the complexity of fungal degradative systems.

Summary: This study investigates the changes in cellulose crystalline structure and chemical composition of Masson pine during brown-rot decay caused by Gloeophyllum trabeum. The results show that the cellulose crystallinity initially increases and then decreases, accompanied by non-enzymatic depolymerization of amorphous cellulose and hemicellulose. These findings provide insights into the degradation and utilization of lignocellulose.

Summary: Photodegradation and decay can occur simultaneously on wood. This study found that photodegradation affects the initial stage of brown-rot decay by changing the wood microstructure and creating new voids for fungal colonization. The photodegradation products promote the non-enzymatic degradation process of brown-rot, but lignin derived compounds inhibit the further activity of decay fungi.

Summary: This study used hyperspectral near infrared imaging to analyze Scots pine sapwood samples exposed to brown rot fungi, finding that the fungi primarily initiated degradation in earlywood and earlywood remained more extensively degraded than latewood even in advanced decay stages. Both fungi produced similar spectral changes in a similar spatial pattern.

Summary: This study analyzed the degradation process of wood by brown rot fungi in two stages and investigated the impact of wood acetylation on their behavior. Clear differences were found in decay strategies among different fungi, with acetylation delaying and attenuating decay. Identifying key genes in these processes can aid in decay detection and biomarker selection for fungi.

Summary: Although plant microtubules are nucleated in a gamma-tubulin-dependent but gamma-TuRC-independent manner, gamma-tubulin is still considered a microtubule nucleator. Plant cells serve as an excellent model for studying the role of gamma-tubulin in nucleation due to their acentrosomal nature and high conservation of gamma-tubulin.

Summary: An improved understanding of the events involved in cell wall polymers deposition during xylem development could provide new scientific ways for molecular regulation and biomass utilization. Axial and radial cells show spatial heterogeneity and highly cross-correlated developmental behavior during xylem differentiation. The deposition of corresponding cell wall polymers in these cell types was found to occur asynchronously, with different patterns and content of polymer accumulation.

Summary: Plastics and microplastics are widely present and accumulating in the environment, leading to increasing public attention. In addition to packaging plastics, materials from industries such as electronics, space and aviation are also accumulating, but receiving less attention. The production of degradable and biodegradable plastics is seen as a way to reduce environmental impacts, but enhancing the non-degradability of functional polymers is also a feasible option. Microbial colonization and deterioration pose significant challenges to these materials.

Summary: This study evaluated the keratinolytic activity of 37 strains of Trichophyton ajelloi and found that pigmented strains isolated from loamy soil were more efficient in degrading native feather keratin, while non-pigmented strains isolated from chernozem showed better abilities. The keratinolytic activity increased over time, as evidenced by the increase in extracellular keratinase activity and release of soluble proteins and peptides. Protease activity peaked in the first 7 days and again on day 28 of culture. The release of ammonium and sulfate ions, associated with an increase in pH, reached its maximum on day 21. Three pigment-producing strains were among the most active in releasing large amounts of ammonium and sulfate ions. The biodegradation of feather waste by Trichophyton ajelloi strains can be used to produce fertilizers suitable for plants with high sulfur requirements.
