Unveiling Ecological and Genetic Novelty within Lytic and Lysogenic Viral Communities of Hot Spring Phototrophic Microbial Mats

Viruses exert diverse ecosystem impacts by controlling their host community through lytic predator-prey dynamics. However, the mechanisms by which ly-sogenic viruses influence their host-microbial community are less clear. In hot springs, lysogeny is …

Antarctic polyester hydrolases degrade aliphatic and aromatic polyesters at moderate temperatures

Polyethylene terephthalate (PET) is one of the most widely used synthetic plastics in the packaging industry, and consequently has become one of the main components of plastic waste found in the environment. However, several microorganisms have been …

Ecogenomics and Adaptation Strategies of Southern Ocean Viral Communities

Viruses are the most abundant biologic entities in marine systems and strongly influence the microbial community composition and diversity. However, little is known about viral communities’ adaptation and diversification in the ocean.The Southern …

Proteorhodopsin Phototrophy in Antarctic Coastal Waters

Proteorhodopsin-bearing microorganisms in the Southern Ocean have been overlooked since their discovery in 2000. The present study identify taxonomy and quantify the relative abundance of proteorhodopsin-bearing bacteria and proteorhodopsin gene …

Influence of Estuarine Water on the Microbial Community Structure of Patagonian Fjords

Fjords are sensitive areas affected by climate change and can act as a natural laboratory to study microbial ecological processes. The Chilean Patagonian fjords (41–56°S), belonging to the Subantarctic ecosystem (46–60°S), make up one of the world's …

Microaerobic conditions in anaerobic sludge promote changes in bacterial composition favouring biodegradation of polymeric siloxanes

Microaeration changes the native anaerobic microbial community composition allowing the degradation of polydimethylsiloxanes and releasing volatile siloxanes into biogas.

Coastal bacterial community response to glacier melting in the western antarctic peninsula

Current warming in the Western Antarctic Peninsula (WAP) has multiple effects on the marine ecosystem, modifying the trophic web and the nutrient regime. In this study, the effect of decreased surface salinity on the marine microbial community as a …

Taxonomic Novelty and Distinctive Genomic Features of Hot Spring Cyanobacteria

Several cyanobacterial species are dominant primary producers in hot spring microbial mats. To date, hot spring cyanobacterial taxonomy, as well as the evolution of their genomic adaptations to high temperatures, are poorly understood, with genomic …

Metagenomic Insights into the Sewage RNA Virosphere of a Large City

Sewage-associated viruses can cause several human and animal diseases, such as gastroenteritis, hepatitis, and respiratory infections. Therefore, their detection in wastewater can reflect current infections within the source population. To date, no …

SARS-CoV-2 Detection in Sewage in Santiago, Chile - Preliminary results

Abstract The detection of viruses in sewage is a method of environmental surveillance, which allows evaluating the circulation of different viruses in a community. This study presents the first results of sewage surveillance to detect the circulation …
