Summary: In this study, the impact of different pipe materials on water quality and microbial communities was investigated using static and dynamic devices. The results showed that steel plastic composite pipe, ductile iron pipe, and cast iron pipe had better water quality, while ductile iron pipe had the highest microbial diversity. Furthermore, various nitrate-reducing bacteria were identified, with nitrate-reducing bacteria being the most dominant in all pipe materials.

Summary: Thermal desorption technology is commonly used to remediate PAH-contaminated soil, but it requires high temperatures. This study found that low temperatures (20-28°C) were optimal for PAH mineralization, which is important for the growth of microorganisms. However, higher temperatures (50°C) inhibited PAH mineralization, but had the greatest detoxification effect. Bacterial communities were found to play a direct role in PAH mineralization and reflected changes in toxicity, highlighting the importance of microbial treatments in soil remediation.

Summary: Bioaugmentation is an effective method for treating oil-polluted seawater with different deep-sea microorganisms, showing a higher oil degradation efficiency compared to natural restoration. The increase in relative abundance of indigenous bacterial genera, such as Cycloclasticus, Alcanivorax, Ulvibacter, and Erythrobacter, played a crucial role in crude oil degradation.

Summary: This study aims to develop a numerical model with high spatial and process resolution to accurately reproduce the transport of heat and salt across the ice-ocean interface. Analytical solutions for the vertical structure of subglacial non-rotational plumes are derived, and numerical formulations for the momentum and tracer fluxes are developed and tested. The model is used to simulate different scenarios and evaluate the performance of existing parameterizations.

Summary: The quality of drinking water deteriorates in the plumbing system, and this study provides evidence of the differences in water quality between the water main and customer taps. Biofilm contributes significantly to the total biomass in distribution pipes, while loose deposits have little contribution. The plumbing system has a significant impact on the active biomass and bacterial community, leading to differences in the relative abundance of certain bacterial species between tap water and the water main.

Summary: Chlorinated aliphatic hydrocarbons (CAHs) are potentially toxic substances that have been commonly found in contaminated environments. This study investigates the composition, function, and assembly of soil bacteria in an aged CAH-contaminated site using high-throughput sequencing analysis. The presence of organohalide-respiring bacteria (OHRB) is crucial in reducing the environmental stress of CAHs and improving the diversity and stability of the bacterial community. The findings suggest that the metabolic community in deep soil can potentially contribute to the monitored natural attenuation technology for CAH-contaminated sites.

Summary: The study characterized the gut and faeces bacterial communities of Porcellionides pruinosus using high-throughput sequencing, revealing higher diversity and richness values in the faecal bacterial community due to low-abundance phylotypes. Common bacterial groups were found across taxa, suggesting potential applications in ecotoxicological assays and biomonitoring processes.

Summary: This study examined the influences of OTUs and ASVs on the patterns of marine microbial diversity and community composition. OTU richness was higher than ASV richness in both water column and sediment samples. However, both methods yielded similar vertical patterns of relative diversity and community composition. The two methods also produced similar community compositions at the taxonomic levels of phyla to families.

Summary: The study found that the oxidation process promoted the formation of non-extractable residues of PAHs and had different effects on mineralization among the three PAHs. Oxidation enhanced the mineralization of high-molecular-weight PAHs but inhibited the mineralization of low-molecular-weight PAH. The inhibition of anthracene after oxidation suggests increased toxicity of soil, which coincided with a decrease in soil nitrification activity, bacterial diversity, and PAH-ring hydroxylating dioxygenase gene copies.

Summary: This study used comparative proteomics to investigate the impact of Corexit dispersant on the metabolism, chemotaxis, biofilm formation, and solvent tolerance mechanisms of the marine hydrocarbon-degrading bacterium strain TT1. The results revealed that exposure to Corexit affects various physiological aspects of strain TT1, providing new insights into the impact of dispersants on microbial hydrocarbon degraders for future oil spill response actions.

Summary: SAAs are synthetic chemicals produced from non-renewable sources, with potential toxic impacts on humans and the environment, while natural derived SAAs from the marine environment are seen as promising due to their low toxicity, environmental compatibility, and biodegradability. The Horizon 2020 EU-funded project, MARISURF, aims to identify and characterize SAAs derived from marine bacteria for commercial use, with recent assessments showing lack of cytotoxicity, mutagenicity, and antioxidant capacity, supporting their potential as environmentally friendly biosurfactants.

Summary: Assembly processes in marine microbial communities amended with crude oil, chemical dispersant, and rhamnolipid are controlled by a combination of deterministic and stochastic factors. Determinism dominates in the early phase, while stochasticity is prevalent in the middle and late stages. Communities amended with dispersant recruit phylogenetically distant species faster compared to oil-only or rhamnolipid-amended communities.

Summary: The study revealed that the natural marine microbial community in the northeast Atlantic responded differently to crude oil dispersed with either synthetic or biogenic surfactants over time. The synthetic dispersant Finasol had a significant negative impact on community diversity and taxa-functional robustness, while the biogenic surfactant rhamnolipid showed higher performance in aromatic hydrocarbon biodegradation.

Summary: Synthetic chemical surfactants (SCSs) are widely used in various industrial applications, but their release into the environment has caused significant damage and potential toxic effects. As a result, there is a growing demand for sustainable alternatives, such as biosurfactants, which are biodegradable and non-toxic. However, the low yields and high production costs of microbial biosurfactants pose challenges for their commercialization. This review focuses on discussing the release of SCSs, their impact on marine organisms and humans, and the potential of microbial biosurfactants as replacements.

Summary: This study used DNA-SIP and metagenomics to investigate the native alkane-degrading bacteria in the Faroe-Shetland Channel. Two previously overlooked hydrocarbon-degrading bacteria, Lentibacter and Dokdonia, were discovered, with Lentibacter being the dominant genus. Additionally, new metabolic pathways and mechanisms for alkane degradation were identified, enhancing the understanding of the diversity and physiologies of alkane degradation in the North Atlantic.

Summary: Time series data from a moored array of sensors are used to describe the long-term mean circulation and seasonal variations on the West Florida Continental Shelf. The observations reveal a coherent shelf-wide circulation pattern with alongshore and down-coast flow, and a coastal jet separating an upwelling region from a downwelling region influenced by the deeper ocean.
