Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes

FEBS Letters, Volume 599, Issue 23, Page 3417-3443, December 2025.
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

Enzyme catalysis in psychrophiles

, 2017
Cold-active enzymes are produced by organisms, known as psychrophiles, adapted to permanently cold habitats. Low temperatures have an exponential deleterious effct on reaction rates, and thus psychrophilic enzymes have to be adapted to secure appropriate

Microbial communities of the Lemon Creek Glacier show subtle structural variation yet stable phylogenetic composition over space and time

Frontiers in Microbiology, 2015
Glaciers are geologically important yet transient ecosystems that support diverse, biogeochemically significant microbial communities. During the melt season glaciers undergo dramatic physical, geochemical and biological changes that exert great ...

PSOSP uncovers pervasive SOS‐independent prophages with distinct genomic and host traits in bacterial genomes

iMeta, Volume 4, Issue 5, October 2025.
Prophages are ubiquitously present in bacterial genomes, significantly influencing host physiological and ecological functions. We present Prophage SOS‐dependency Predictor (PSOSP), a novel bioinformatics tool that predicts prophages induction modes by analyzing the Heterology Index (HI) of LexA protein binding to target DNA, classifying prophages into

Metagenomic Analysis of Low-Temperature Environments

, 2017
The Earth’s permanently cold biosphere is known to harbour abundant microbial biomass and represents a rich resource for the discovery of novel cold-adapted microorganisms, many of which form part of the ‘microbial dark matter’ which cannot be analysed ...

Identification and Global Distribution of a Core Microbiome From High‐Arctic Lakes

Environmental Microbiology, Volume 27, Issue 10, October 2025.
Identification of the core microbiome from clear water lakes in the Arctic reveals non‐unique members when compared with a conceptually similar lake from a more temperate region. Biogeographic assignments revealed that the genera from this core were widespread globally within four general habitat categories.

Discovery, Molecular Mechanisms and Industrial Applications of Cold-Active Enzymes

Frontiers in Microbiology, 2016
Cold-active enzymes constitute an attractive resource for biotechnological applications. Their high catalytic activity at temperatures below 25 ºC makes them excellent biocatalysts that eliminate the need of heating processes hampering the quality ...

An Unexpected Facet of Extremophiles: Their Aesthetic Potential in Artistic Expression

Microbial Biotechnology, Volume 18, Issue 10, October 2025.
In an era marked by environmental challenges and the proliferation of misinformation, the fusion of art and science is a strategy to promote public understanding and appreciation of complex scientific phenomena. We illustrate how the use of extremophiles offers novel avenues for artistic exploration and emphasise the benefits of such interdisciplinary ...

Influence of Plant Species and De‐Icing Salt on Microbial Communities in Bioretention

Environmental Microbiology Reports, Volume 17, Issue 5, October 2025.
Plant species shape bioretention bacterial and fungal communities and their associated functions, which drive system efficiency. These results underscore the importance of plant selection when designing bioretention systems. Moreover, the communities were preserved or recovered within 5 months after the exposure to NaCl levels typical of spring runoff.
