Summary: The effects of Desulfovibrio desulfurican (D. desulfurican) and Pseudomonas stutzeri (P. stutzeri) on the biocorrosion of X80 pipeline steel were investigated for different concentrations of nitrate and nitrite. The results indicated that both nitrate and nitrite treatments significantly reduced the number of D. desulfurican cells, with nitrite exhibiting a stronger inhibition effect. Moreover, nitrite treatment formed gamma-Fe2O3 passivation films on the surface of the steel, inhibiting the formation of erosion pits. Additionally, nitrite also led to a significant decrease in FeS content, which helped to reduce corrosion.

Summary: In this study, the wall painting in the apse of the Sotterra church in Italy was analyzed using a diagnostic approach. The oldest painting, dating back to the 11th-12th centuries, was the focus of the study. Noninvasive analysis and laboratory-based methods were used to determine the composition of materials and the causes of alterations affecting the wall painting. Additionally, an environmental monitoring campaign was conducted to assess the indoor climate. The results revealed the use of natural mineral pigments and the presence of calcium sulfate, which contributed to the understanding of crystallization and condensation risks.

Summary: Microbiologically influenced corrosion (MIC) is common in various industries, and sulfate-reducing bacteria (SRB) often contribute to MIC. This study isolated a strain of Pseudomonas stutzeri (P. stutzeri) from soil, which has the ability to inhibit SRB corrosion. P. stutzeri can coexist with SRB in the same growth environment, and it effectively inhibits the corrosion of X70 steel caused by SRB under specific conditions.

Summary: This study investigated the responses of electrotrophic communities in paddy soil to different long-term fertilization practices, revealing significant changes in the community structure. The dominant electrotrophs were identified as Streptomyces genus in the CK, M, and MNPK soils, while Proteobacteria and Firmicutes were major electrotrophs in the NPK soil. Furthermore, it was found that electrotrophs enhanced dissimilatory nitrate reduction to ammonium (DNRA) for all soils.

Summary: Quorum sensing is a cell communication mechanism that is essential for infection development by pathogenic microorganisms. It controls various virulence factors and disrupting this mechanism can help combat multi-drug resistance. Marine epibiotic bacteria have been used to obtain novel bacterial strains that produce quorum sensing inhibitory compounds.

Summary: The organisms inhabiting built cultural heritage can passively or actively participate in conservation processes. Active participants are focused on for their positive roles in various processes, as well as providing ecosystem services. These organisms can also evolve or mutate in response to changes and acquire new capacities. Recent studies have opened up new avenues of research involving a wide variety of organisms and viruses, which are expected to gain more attention in the future.

Summary: The innovative methodology proposes the use of dry biocleaning with dehydrated microbial cells for the recovery of altered stonework, showing better removal of salts and pollutants compared to traditional cleaning techniques. The on-site tests demonstrated the effectiveness of the spontaneous re-hydration process and metabolic fermentative activity of yeast cells in the recovery process. Adopting viable yeast cells in the dry biocleaning technique presents a promising method for further investigation and optimization in recovering specific altered Cultural Heritage stoneworks.

Summary: Bacteria generate and release extracellular reactive oxygen species (eROS), which significantly contribute to the natural ROS pool and play a crucial role in metabolic interactions of bacteria with their environment. Understanding the behavior of eROS-generating bacteria and its environmental implications is of great importance in the cycling of biogeochemical elements, transformation of organic matter, and regulation of antibiotic resistance genes.

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: The incomplete recycle of residual mulch film (RMF) in recent years has led to an increase in plastic fragments in soil, posing a serious threat to the soil ecological environment. In this study, seven potential plastic-degrading microorganisms were screened and identified from film-mulched vegetable fields. The degradation ability experiments showed that both single strains and mixed strains demonstrated varying levels of degradation of RMF.

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.

Summary: This study investigated the phenomenon of Centimetric circular areas Uncolonized by Microbial Biofilms (CUMBs) on natural and heritage stone surfaces. The analysis revealed a compatibility in distribution and size between CUMBs and lichen thalli, suggesting a lichen origin for some CUMBs. Microscopic analysis also showed similar modifications in marble layers beneath CUMBs and lichens, indicating a possible alteration of stone properties by lichens.
