Summary: The composition of the passive film on alloys affects the selection of microbial biofilms, but the mechanism is not fully understood or incorporated into the analysis of corrosive biofilms. The degradation of stainless steel exposed to natural seawater was studied to investigate how the oxide layer composition influences the bacterial community. Austenitic and superferritic stainless steel grades were exposed to natural seawater, and the corrosion and biofilm formation were monitored. Bacterial communities were analyzed through massive sequencing, and the results showed that the similarity of bacterial community correlated with the variability of corrosion rate, with higher representation of certain bacterial families in stainless steels with an increased Fe/Cr ratio. Iron content in the oxide layer is found to be a key feature in selecting bacterial assemblages in marine environments.

Summary: This study used 16S rRNA high-throughput sequencing to analyze the bacterial community composition and function in traditional fermented yak milk. The results showed that there were 13 different phyla and 82 different genera present in the yak milk, with the phylum Firmicutes being the dominant phylum (98.94%) and Lactobacillus (64.73%) and Streptococcus (28.48%) as the dominant genera. The bacterial community richness and diversity were highest in Manang Village, followed by Bola Village, while Huage Village had relatively low richness and diversity. Furthermore, the analysis of Kyoto Encyclopedia of Genes and Genomes (KEGG) functional classification revealed that the microorganisms in traditional fermented yak milk have rich metabolic functions (77.60%). These findings provide a theoretical foundation for further exploration of the microbial flora in traditional fermented yak milk in Gannan.

Summary: Biofilms are the predominant living presence of microorganisms on surfaces of cementitious materials, and their formation can lead to biodeterioration. Extensive research studies have been conducted to understand the basic mechanisms of biofilm formation and material deterioration, resulting in the development of analytical techniques to describe the chemical compositions, structural characteristics, and microbial diversity of these biofilms. This review article presents the latest technical developments and critically analyzes the use and limitations of these techniques, providing valuable insights for the scientific community. Additionally, new methods from other fields of microbial biofilm investigation are discussed, emphasizing the importance of physico-chemical characterization in understanding the interactions between biofilms and cementitious materials.

Summary: The study in a natural fir-beech forest in the Czech Republic found high spatial variability and beta diversity in fungal communities across deadwood of Fagus sylvatica and Abies alba over a succession series of more than 40 years. As deadwood aged, fungal abundance, diversity, and activity increased. pH and the carbon to nitrogen ratio (C/N) were key predictors of fungal community composition, influencing the abundance of dominant fungal taxa.

Summary: All types of building materials are susceptible to microbial colonization, leading to biodeterioration. While current cleaning techniques offer good cost-benefit ratios, they have limitations and face challenges in terms of microbial resistance and ecotoxicity. There is an urgent need for innovative and eco-friendly solutions to combat biodeterioration effectively.

The s/s PCMs have a significant impact on consistency and yield strength values. By modifying existing viscosity models, the consistency value of suspensions can be predicted, providing a new approach for the use of s/s PCMs in construction materials.

Summary: Research has shown that pioneer moss biocrusts have significant effects on the recovery and resilience of soils in early post-fire stages in semi-arid areas. These biocrusts can soften the impact of wildfires on soil, alter the diversity and composition of microbial communities, and affect the physicochemical and biochemical properties of soil. The presence of moss biocrusts promotes rapid successional transition of soil microbial communities and plays a crucial role in improving their resilience.

Summary: Soil fungi play essential roles in ecosystems, including organic matter recycling and interactions with plants. Global change factors, such as increased CO2 concentration, temperature, precipitation changes, and nitrogen deposition, have been shown to affect fungal species and communities in soils. Nitrogen deposition appears to have the most significant impact on fungal communities. Plant mutualistic fungal guilds, such as ectomycorrhizal fungi and arbuscular mycorrhizal fungi, are particularly responsive to global change factors, with nitrogen deposition and warming having the strongest adverse effects. Although global change has limited effects on fungal biodiversity, studies demonstrate an increase in abundance and dispersal of plant pathogenic fungi. Ecosystems weakened by global change-induced phenomena, like drought, are more susceptible to pathogen outbreaks. The shift from mutualistic fungi to plant pathogens poses the most significant potential threat to the functioning of natural and managed ecosystems in the future. However, our ability to predict global change effects on fungi is still insufficient and requires further experimental work and long-term observations.

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.
