Summary: This study investigated the effects of growth time and silver nitrate concentration on the synthesis of AgNPs, highlighting the role of capping proteins in determining the size of nanoparticles. The best synthetic properties were found at 1 mM of AgNO3 concentration, 8 days of growth time, and 144 hours of reaction time. Obtaining nanometals from microorganisms could be a new method of synthesis with low-cost and reduced toxic waste generation.

Summary: Heavy metal contamination is a major environmental and societal challenge. This study evaluates the use of the white rot fungus Phlebia floridensis for the removal of mercury from wastewater. The fungus is capable of tolerating high concentrations of mercury and can remove 70% to 84% of the mercury in the treated water. The study demonstrates the potential application of this fungus for metal containing wastewater treatment.

Summary: This study investigated the degradation of graphene oxide (GO) by the white-rot fungus Phanerochaete chrysosporium and found that lower concentrations of GO stimulated the growth and enzyme production of the fungus more effectively than higher concentrations. The presence of GO altered the structure of the fungus and affected the activity of lignin peroxidase (LiP) but not laccase (Lac). Lac caused modifications in the GO lattice. These findings highlight the importance of Lac in the biodegradation of graphene materials in terrestrial ecosystems.

Summary: The red emissive carbon quantum dots showed low toxicity and even slightly stimulated the growth of white rot fungus, with no significant impact on its decomposition activity. The fluorescence quenching of carbon quantum dots in the fungus implied biotransformation during incubation.

Summary: The wastewater containing antibiotics from hospitals, pharmaceutical industries, and human and animal excretion poses a significant threat to the environment. This study investigated the ability of three fungal strains to degrade the fluoroquinolone antibiotic levofloxacin. The results showed that Coriolopsis gallica strain CLBE55 exhibited the highest removal efficiency, with a 15% decrease in antibiogram zone of inhibition for Escherichia coli in solid medium and a 25% degradation of the antibiotic in liquid medium. Proteomic analysis suggested the involvement of laccases and dye-decolorizing peroxidases in the degradation process, with laccases playing a major role. Mass spectrometry analysis confirmed the formation of an N-oxidized derivative as the main product of levofloxacin biotransformation by Coriolopsis gallica.

Summary: In order to improve the treatability of refractory wood and heartwood, the effects of bioincising treatment with white-rot fungus Trametes versicolor on radiata pine heartwood were studied. The results showed that the optimal inoculation time of T. versicolor was 4 to 8 weeks, during which the retention of injected preservatives increased, the penetration depth of preservatives increased significantly, and the corresponding mass loss was observed. The microstructure and pore structure analysis revealed that T. versicolor degraded pit membranes and ray parenchyma cells early in the inoculation, increasing the porosity and range of pore size distribution, thus improving the treatability of radiata pine heartwood.

Summary: This research demonstrates for the first time that the white-rot fungus Trametes versicolor can secrete extracellular droplets containing high concentrations of fatty acids and sugars. The composition and concentration of the droplets varied according to the droplet's age and the feedstock used for fungal growth. These findings suggest a new approach for microbial oil generation from waste.

Summary: Dichomitus squalens is an emerging reference species for investigating plant biomass degradation. Recent genomic studies have provided detailed knowledge of the genes and enzymes involved in lignocellulose breakdown in this fungus. Developing efficient genetic manipulation tools is crucial for utilizing this data, as precise genome alterations are often challenging in wild-type basidiomycetes.

Summary: This study demonstrates that carbonization treatment can reduce the toxicity of metal-organic framework materials to white-rot fungi and protect their decomposition ability. Compared to untreated MOF materials, carbonized materials are more conducive to fungal enzyme activity and decomposition capability, while reducing environmental hazards.

Summary: Plastic waste has been accumulating in the environment since the 1980s, but little is known about fungi biodegradation in dry environments. This study showed that Phanerochaete chrysosporium (P. chrysposporium), a white rot fungi, could efficiently degrade polylactic acid (PLA) and polystyrene (PS). The visualization of the degradation process and its negative effects on cell development were presented, and potential genes and pathways involved in plastic degradation were identified.

Summary: The study found that P. ostreatus has the potential to degrade DBDPE and effectively remove harmful substances from the environment, although coexisting substances like lead may inhibit its degradation efficiency. Enzymatic activity, particularly Lac, played a key role in the biodegradation process, while toxic responses included enhanced SOD and CAT activities.

Summary: This study reveals the efficient transformation of imidacloprid (IMI), a widely used neonicotinoid insecticide, by white-rot fungus Phanerochaete chrysosporium, resulting in the production of a less neurologically toxic metabolite. The study elucidates the metabolic mechanism of IMI by the production of extracellular manganese peroxidase and lignin peroxidase by the fungus. This research highlights the potential of fungi for IMI transformation and provides insights into the fate of IMI in the environment.
