Summary: The study demonstrates that copper in micronized copper-treated wood dissolves and migrates into adjacent soil and water primarily in ionic form, not as nano-sized copper particles. A reduced form of copper (Cu2S) is identified in deep soil near treated wood, reducing movement of dissolved copper to water and diminishing exposure risk.

Summary: This study aimed to degrade high molecular weight PLA films during traditional composting by adding a PLA-degrading bacterial consortium (EAc). With EAc bioaugmentation, PLA films had complete disintegration in 35 days, 77-82% molecular weight reduction in 16 days, and higher CO2 liberation and mineralization compared to non-bioaugmented composting. The bacterial community analysis showed that EAc bioaugmentation increased the relative abundance of the polymer degrader Schlegelella and interacted positively with beneficial indigenous microbes. The bioaugmentation also decreased compost phytotoxicity.

Summary: The study aims to develop a bacterial consortium that can biodegrade high molecular weight semi-crystalline polylactic acid (PLA) films at ambient temperature. PLA-degrading bacteria were enriched from polymeric wastes, and four isolated bacteria were mixed as a consortium. The results showed that the consortium successfully degraded PLA films, and the degradation performance was significantly better than that of individual strains.

Summary: Thermo-mechanical densification modifies wood to produce a more dense and resistant material and may degrade extractives that contribute to increased susceptibility to attacks. This study evaluated the efficiency of tannin extracts of Acacia mearnsii in the treatment of thermo-mechanical densified pine wood, showing improved physical, mechanical, and biological resistance properties. The modified wood treated with tannin extracts exhibited significantly higher density, increased mechanical strength, reduced termite damage, and improved resistance. This highlights the potential of thermally modified wood preserved with tannin as a high-performance material.

Summary: Delignified porous wood samples were used as carriers for biofilm formation of a bacterial consortium with the ability to degrade 1,4-dioxane (DX). The treated wood exhibited higher porosity, surface roughness and hydrophilicity, resulting in increased growth of biofilm compared to untreated wood. The study also showed that the treated wood effectively degraded DX, while the untreated wood had lower removal efficiency.

Summary: This study addresses the issue of overestimation of the actual elastic response of structural timber connections by finite element models, proposing a control parameter called stiffness contact. The method for determining stiffness contact based on the geometry of a rectangular contact area is demonstrated through experimental campaigns on dowel embedment and moment resistant wood joint tests, showing good agreement with the experimental results.

Summary: Petroleum hydrocarbon contamination is a major concern for the environment and public health. In this study, a microbial consortium capable of degrading petroleum hydrocarbons was enriched using crude oil. 16S rRNA gene analysis revealed the structural characteristics of this community, while metagenomic analysis identified the specific microbial organisms and metabolic pathways involved in the degradation of cyclohexane and BTEX components. The results demonstrated the synergistic interactions between different bacterial genera during the hydrocarbon degradation process.

Summary: The study found that natural diversity of wood decaying communities were more effective at decomposing wood compared to reduced species richness, but the latter increased wood pH. In environments with reduced species richness, there were more mutual exclusions in microbial co-occurrence networks, but microbial communities can recover previous ecosystem functions through reassembly.

Summary: The relationship between active microbes and soil ecosystem functions in a grassland ecosystem is significant, with active microbes playing a crucial role in defining soil functions. The study reveals that total and active microbiomes respond differently to variations in soil physicochemical factors, with nitrogen fixing bacteria being highly active in this system. The findings suggest a stronger link between biodiversity and ecosystem functioning in soil than previously believed.

Summary: Deadwood is a crucial part of the global carbon cycle and its decomposition releases CO2 and CH4 into the atmosphere. However, the main factors driving these greenhouse gas emissions from deadwood are not well understood. In this study, we investigated the drivers of CO2 and CH4 emission rates from deadwood specimens of different tree species exposed in forest and grassland habitats. We found that tree species identity, habitat type, management intensity, wood traits, and climate variables all play a role in determining emission rates.

Summary: In this study, the PHB formation, biomass, and elemental composition of Leptolyngbya sp. NIVA-CYA 255 were investigated. The highest PHB yields were detected in NP- and N-deficiency conditions. The glycogen pool was reduced during mixotrophy, while lipid composition was not affected. This suggests that Leptolyngbya sp. NIVA-CYA 255 is a promising candidate for PHB production.

Summary: This study investigated biological nitrogen fixation (BNF) rates and nifH gene abundances in deadwood of different tree species, and found that diffuse-porous angiosperms had higher BNF rates and nifH gene abundances. Relationships with nutrient concentrations and non-structural carbohydrates indicated that BNF in deadwood was co-limited by multiple nutrients, while high carbon availability was beneficial for diazotrophs. Water content was also found to be important for BNF and nifH gene abundance. The study suggests that BNF is a common microbial process in deadwood of native European tree species, and high nitrogen deposition does not down-regulate BNF in Central Europe.

Summary: The fungal human pathogens, Candida auris and Candida albicans, have various virulence mechanisms, including the formation of biofilms and the development of (pseudo)hyphae to protect against harsh conditions and facilitate invasion of host tissues. Increasing rates of antifungal resistance in these pathogens pose a challenge for effective treatment. This study found that rubiginosin C, derived from the ascomycete Hypoxylon rubiginosum, effectively inhibited biofilm formation and hyphal development in both C. auris and C. albicans without harming host cells. Rubiginosin C is a promising candidate for therapeutic intervention in the future.

Summary: This study found that the cuticular microbiomes of solitary bees are more complex than those of social honeybees. The microbiome composition is similar among different honeybee subspecies, but subspecies adapted to warmer climates have different numbers of fungi and higher diversity. These results suggest that the cuticular microbiome of bees is influenced by visited plants, lifestyle, and climate, which is important for maintaining bee health under global change conditions.
