Summary: This study investigated the biodegradation mechanism of chloroxylenol by fungal strains and analyzed the ecotoxicity of emerging by-products. The results showed a high elimination rate of PCMX by the tested microorganisms, and the identification of new fungal by-products. Furthermore, the study revealed a detoxifying nature of the biodegradation process of PCMX.

Summary: Melanin is a heteropolymer formed by the polymerization of phenolic and indolic compounds, with various protective advantages such as against ultraviolet radiation, traumatic damage, oxidative stress, extreme temperatures, and pressure. In many fungi, melanin plays a direct role in pathogenicity, with the ability to synthesize it in different ways, either endogenously with 1,8-dihydroxynaphthalene (DHN) or exogenously with L-3, 4-dihydroxyphenylalanine (L-DOPA). The complex and amorphous nature of melanin makes it challenging to study with conventional biochemical techniques, especially in nematophagous fungi which are still poorly understood.

Summary: This study developed a laccase-mediator system using natural mediators for melanin decolorization, effectively overcoming issues such as the low redox potential of laccase and limited access of melanin to the active site. Natural mediators with methoxy and ketone groups played a crucial role in melanin decolorization, and using acetosyringone as a mediator significantly enhanced the specificity constants of laccases. The laccase-mediator system could decolorize synthetic eumelanin analogs and natural melanin produced by melanoma cells, showing promising potential for skin whitening applications.

Summary: Humans are frequently exposed to filamentous fungi, which are widespread in the environment. Under certain risk factors, these non-dermatophyte fungi can become opportunistic pathogens and cause various types of infections. The use of molecular tools and taxonomic revisions has led to the identification of an increasing number of fungi in humans. This review aims to inventory these filamentous fungi and provide details on their anatomical locations and the symptoms of infections.

Summary: This study analyzed all FK cases diagnosed in a tertiary care hospital in northern Thailand between August 2012 and December 2020, finding a higher incidence of FK during the rainy season, with males and middle-aged adults being at highest risk. Fusarium spp. and dematiaceous fungi were the main pathogens causing FK, with the hyphal morphogenesis and melanization of molds playing important roles in the disease.

Summary: The pentose phosphate pathway (PPP) is a key pathway in metabolic engineering, providing NADPH and playing a role in the production of various compounds in fungi. Understanding the regulatory mechanisms of PPP can lead to targeted engineering and improved performance in industrial fungal strains.

Summary: Melanized fungi isolated from harsh radioactive environments show an adapted strain response to ionizing radiation, with transcriptomic changes and unique gene expression patterns. Exposure to radiation primes the fungus for subsequent exposures in a distinct way, broadening our understanding of how melanized fungi interact with ionizing radiation in their environment.

Summary: Fungal spore killers are genetic elements that promote their own inheritance by killing non-inheriting gametes. However, little is known about how they kill other spores within the fungal ascus. In this study, we investigate the spore killer protein SPOK1 in Podospora anserina and demonstrate that it kills by targeting DNA. This finding provides insights into the mechanisms of spore killers and their potential applications.

Summary: The occurrence of mycotoxins in forage, particularly in grass silages, can heavily impact the amount of toxins consumed by cattle. A study conducted in Finland found mycotoxins in 92% of the grass silage and whole-crop cereal silage samples, with beauvericin and roquefortine C being the most common mycotoxins. The survey results suggest that silage-fed ruminants can be exposed to a wide range of mycotoxins, and the presence of visible molds does not guarantee mycotoxin-free feed.

Summary: This study investigated the fermentation conditions for Trametes versicolor to degrade aflatoxin B1 (AFB1) in corn and its effect on the nutritional composition of corn. The optimal conditions for AFB1 degradation were determined, and the fermentation of AFB1-contaminated corn by T. versicolor was found to not only efficiently degrade AFB1 but also improve the nutritional value of corn. These findings suggest that the fermentation of corn by T. versicolor is a promising, environmentally friendly, and efficient approach to degrade AFB1 and improve the nutritional value of corn.

Summary: The ABC transporter superfamily plays a crucial role in transporting various molecules across biological membranes, including antifungal compounds in filamentous fungi. Understanding the physiological substrates and roles of individual subfamilies of ABC transporters in fungi is important for clarifying their significance in clinical and agricultural settings.

Summary: Hydrophobins are small-secreted proteins with hydrophobic and hydrophilic parts that can form amphiphilic films at the air-liquid interface. In the white-rot fungus Pleurotus ostreatus, more than 20 hydrophobin genes have been identified. Previous studies have shown that three hydrophobin genes are mainly expressed under ligninolytic conditions, and the vmh3 gene is downregulated in delignification-deficient mutant strains. This study focuses on the function of hydrophobin Vmh3 and demonstrates its role in lignin degradation.

Summary: This study investigates the functional MSUD system in Bipolaris maydis and suggests that ascus dominance in this fungus is caused by RNA silencing triggered by unpaired DNA, similar to Neurospora crassa. The study also shows the conservation of posttranscriptional regulation in filamentous ascomycetes.

Summary: The study found that the HPt protein in the histidine-to-aspartate phosphorelay system plays a crucial role in responding to environmental stresses in the filamentous fungus Aspergillus nidulans. Activation of HPt is associated with cellular responses such as enhanced septation, nuclear fragmentation, and vacuole hypertrophy.
