Summary: Excessive sulfate levels are harmful to the environment and human health. This study aimed to find readily available organics for sulfate-reducing bacteria (SRB) in order to tackle sulfate pollution and develop sulfate removal and sulfur recovery methods. The research explored the utilization of different carbon sources by SRB, including alcohols, small organic acids, and sugars, and their impact on microbial sulfate reduction. The results showed that the conversion pathways of carbon sources and the presence of incomplete oxidizers significantly influenced the sulfate reduction process, as well as shaping the microbial community.

Summary: Inhibiting sulfate-reducing bacteria (SRB) has shown various effects on microbial community properties and coexistence patterns, indicating the importance of SRB in organic matter (OM) degradation. Suppression of SRB resulted in decreased relative abundances of several bacterial families and altered network and community assembly processes. These findings highlight the essential role of SRB in OM degradation.

Summary: Phosphogypsum (PG) generated during phosphoric acid production contains a significant amount of sulfate, which can be biologically converted into sulfide. This study focuses on selecting and evaluating microbial consortia from sulfate-rich environments for the initial step of sulfur recovery. The MYC-consortium isolated from a hydrothermal niche showed the highest reduction capacity and performance under various conditions. This research provides insights into the potential of the MYC-consortium in converting sulfate from PG into sulfide, which is a critical step in sulfur biorecovery.

Summary: In this study, biochar was used as a carrier to immobilize the heavy metal tolerant sulfate-reducing bacteria SRB14-2-3 for the passivation of Zn-contaminated soil. The results showed that the immobilized bacteria exhibited effective passivation performance, reducing the bioavailable Zn fractions in the soil by up to 34.2%, 30.0% and 22.2% compared to the control group. The introduction of SRB14-2-3 into biochar alleviated adverse effects on the soil and significantly improved the reproduction of SRB14-2-3.

Summary: This study investigated the response and adaptation mechanisms of granular and flocculent sulfate-reducing bacteria (SRB) sludge to acidic metal-laden wastewater (AMW). The results showed that the flocculent SRB lost more than 50% of their treatment capacity, while the granular SRB maintained a high metal removal rate throughout the trial. The stability of the granular structure and microbial activity was found to be influenced by the extracellular glycosyl compositions.

Summary: This study used iron-reducing bacteria and sulfate-reducing bacteria for microbiologically-assisted reduction experiments to assess their effectiveness in alleviating arsenic pollution in soil. The results showed that different bacterial sequences and flow methods had an impact on the release and species of arsenic. Furthermore, chemical treatment only removed a portion of the arsenic, indicating that reductive dissolution and the formation of FeS were the main driving factors for arsenic release.

Summary: This study investigates the mode of action of Zosteric acid (ZA), a secondary metabolite of seagrass with antibiofilm activity against fungi. The researchers analyzed the metabolic status and protein expression profile of Candida albicans biofilm upon ZA treatment. They found that ZA modified the metabolomic response of treated cells, mainly affecting the protein compartment. Additionally, ZA affected the expression of proteins involved in cell wall structure, adhesion, and stress response. The study also demonstrated the involvement of ZA in non-DNA-based epigenetic regulation triggered by reactive oxygen species.

Summary: Bacterial biofilm is a major cause of persistent infection and antibiotic resistance. This study investigates the antibiofilm properties and mode of action of ellagic acid (EA), a natural polyphenol. The researchers propose that EA disrupts the bacterial redox homeostasis mediated by the NADH:quinone oxidoreductase enzyme WrbA, leading to its antibiofilm activity. These findings provide new insights into the potential use of EA for treating biofilm-related infections.

Summary: Neurodevelopmental disorders (NDDs) encompass a range of congenital pathological conditions that affect cognitive, social behavior, and sensory/motor functioning. Recent research has linked genetic disorders involving purine metabolism to autism-like behaviors in humans. Dysregulated purine and pyrimidine levels have also been found in biofluids of individuals with other NDDs. Blocking specific purinergic pathways has been shown to reverse cognitive and behavioral defects in rodent models of NDDs. These findings suggest that targeting P2 receptor signaling could lead to the development of more specific treatments and early detection markers for NDDs.

Summary: The lack of information regarding the degradation mechanisms of Australian outdoor stone heritage currently restricts its protection. This study analyzed the bacterial community colonizing the stone surface of an outdoor sculpture in Melbourne, providing an overview of the microbial composition patterns associated with stone in a human-made environment. The findings revealed a diverse community consisting of phototrophic and chemotrophic microorganisms, characterized by arid, salty, and urban environments. Factors such as cardinal exposure, position, and surface geometry influenced the microbial community structure. This pioneering research contributes to the identification of deterioration-associated microorganisms and beneficial bacteria for stone preservation.

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.

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.
