Summary: The study found that marine foams have a high abundance of phototrophic and prokaryotic cells, as well as a high concentration of surface-active substances. The bacterial communities in foams differ significantly from the sea-surface microlayer and underlying water, characterized by a high abundance of Gammaproteobacteria. Despite differences in overall bacterial composition, the presence of SML bacteria in foams suggests that foams are strongly influenced by the SML.

Summary: The sea surface microlayer (SML) is a thin film at the interface between oceans and the atmosphere. Three different SML samplers were used to collect microbiological DNA samples, showing that during low wind conditions there were biological matter and distinct bacterial communities in the SML. High wind speed conditions led to depletion of biological matter and increased similarity in biological communities between the SML and underlying water, with certain bacterial taxa consistently enriched or depleted in the SML regardless of sampling method.

Summary: In this study, the effects of different plant species on microbes, EPS production, and soil aggregation were investigated in two sites in southern Spain. It was found that plant species and site influenced the microbial communities in the rhizoplane, with site being the most important factor. Higher carbonate content in soil reduced the plant-specific effects on microbial communities and subsequent soil aggregation. This study highlights the importance of plant-microbe interactions in soil ecosystem dynamics and the role of soil properties in moderating these interactions.

Summary: The worldwide growth in plastic production and insufficient waste management have resulted in significant environmental pollution. This study proposes a workflow utilizing advanced data analysis and processing tools to characterize the degradation of polymers in water, as well as the composition of microbial communities involved in their degradation. The results show that hydrolysis of ester groups and formation of cyclic polycaprolactone oligomers are the dominant degradation processes, and the composition of microbial communities varies among different wastewater treatment plants and stages. The microbial communities attached to the polymer may serve as potential consumers.

Summary: Up to 400 million tons of carbon from airborne semivolatile aromatic hydrocarbons are deposited into the oceans annually, making it the largest known source of anthropogenic organic carbon in the ocean. Microbial degradation is an important process for removing these pollutants in surface waters, but has not been extensively studied in polar environments. This research investigates the response of Antarctic microbial communities to polycyclic aromatic hydrocarbons (PAHs) in the sea-surface microlayer (SML) and the subsurface layer (SSL). The study finds that microbial degradation rates are higher in the SML, especially for hydrophobic and particle-bound PAHs. The composition of particle-associated bacteria in the SML also significantly changes after 24 hours of PAHs exposure. This study highlights the crucial role of bacterial populations in the SML, particularly those associated with particles, in removing aromatic hydrocarbons in the oceans.

Summary: This study conducted concurrent measurements of PAHs and environmental data during three austral summers in Antarctica. It found that the temporal trend of PAHs in coastal waters is closely related to the composition of the bacterial community and snow melting input. The biodegradation of PAHs was found to be higher in the Livingston 2015 campaign compared to the Deception 2017 and Livingston 2018 campaigns.

Summary: Coastal ecosystems are deteriorating due to human-induced stress factors, and bacteria play a critical role in these ecosystems. However, methodological limitations have hindered the understanding of bacterial functions and their role in ecosystem health. Advances in molecular biology and bioinformatics methods offer opportunities to overcome these limitations. It is important to categorize the responses of key marine bacterial populations to environmental changes and conduct systematic field studies and experimental analyses to establish the field of genetic counseling for coastal waters.

Summary: Background and chronic pollution by organic pollutants (OPs) is a widespread threat in the oceans, and the effects of anthropogenic dissolved organic carbon (ADOC) on marine ecosystems and major biogeochemical cycles are still not well understood. This study analyzed the metabolic capacity of oceanic communities challenged with environmentally relevant levels of ADOC and found that ADOC-exposed genomes from the Atlantic showed a stronger transcriptional response compared to the Pacific, indicating the higher relevance of ADOC compounds in oligotrophic environments. The study also observed the consumption of anthropogenic hydrocarbons and synthetic chemicals at low concentrations in the ocean and the modulation of microbiomes by ADOC.

Summary: Wastewater Treatment Plant (WWTP) effluents are significant sources of antibiotics, antibiotic resistance genes (ARGs), and resistant bacteria, posing threats to aquatic biota and human health. This study explores the impact of the antibiotic doxycycline on the microbiome of Daphnia magna in lab water and treated wastewater media. The results indicate that doxycycline and the media significantly influence the composition of the Daphnia-associated microbiome, with notable changes in Enterococcus spp. Furthermore, doxycycline reduces the presence of Limnohabitans sp. and impairs Daphnia reproduction in lab water, while treated wastewater increases microbiome diversity, richness, and promotes fecundity. The study also detects various ARG genes, including qnrS1, sul1, and blaTEM, with a higher abundance in treated wastewater compared to lab water.

Summary: This study compared the differences in PAH degradation between coastal Mediterranean and Antarctic waters and found that microbial degradation of PAHs is much more efficient in the Mediterranean than in the Antarctic. Metatranscriptomic analysis showed significant enrichment of PAH degradation genes in the Mediterranean microbiome, while minimal responses were observed in the Antarctic. These findings suggest that factors such as geographic region, microbial community composition, and pre-exposure history play important roles in predicting PAH biodegradation in seawater.
