Stable isotope phenotyping via cluster analysis of NanoSIMS data as a method for characterizing distinct microbial ecophysiologies and sulfur-cycling in the environment

Frontiers in Microbiology, 2016
Stable isotope probing (SIP) is a valuable tool for gaining insights into ecophysiology and biogeochemical cycling of environmental microbial communities by tracking isotopically labeled compounds into cellular macromolecules as well as into byproducts ...

Paving the Way to Elucidate Hg's Role in Tumorigenesis

Advanced Science, Volume 13, Issue 30, 28 May 2026.
Tumorigenesis can result from diverse environmental carcinogens. Among them, mercury—a lifelong bioaccumulative Group 2B carcinogen—has tumorigenic potential that remains poorly understood due to confounding co‐exposures and limited organ‐specific data.

Membrane Vesicle Formation Removes Iron Sulfide Mineral Crusts From the Cell Surface of Growing Sulfate‐Reducing Bacteria

Geobiology, Volume 24, Issue 3, May/June 2026.
ABSTRACT Sulfate‐reducing bacteria (SRB) drive the process of sulfate reduction in low‐temperature sedimentary environments. Through the production of sulfide, they promote the formation of iron‐sulfide (Fe‐S) minerals when Fe(II) is available. The negative charge of the cell surface of bacteria can promote the binding of Fe(II), leading to the ...

Aqueous alteration in C2‐ung Bells through the analysis of carbonates – Does a CR origin ring true?

Meteoritics &Planetary Science, Volume 61, Issue 5, Page 927-941, May 2026.
Abstract Bells is an ungrouped carbonaceous chondrite that has in recent years been proposed as a CR‐an. This link to CR chondrites has previously been identified through the analysis of anhydrous silicates, for example, oxygen isotopic compositions of olivine (Marrocchi et al., 2023).

Quantitation and Comparison of Phenotypic Heterogeneity Among Single Cells of Monoclonal Microbial Populations

Frontiers in Microbiology, 2019
Phenotypic heterogeneity within microbial populations arises even when the cells are exposed to putatively constant and homogeneous conditions. The outcome of this phenomenon can affect the whole function of the population, resulting in, for example, new

Gut Microbiomes of Marine Zooplankton: Consequences for Host Performance, the Biological Carbon Pump, and Prokaryote Biogeography

Environmental Microbiology, Volume 28, Issue 4, April 2026.
Expected effects of zooplankton microbiota on the host and on the ecosystem. Stylized mesozooplankton holobiont (center) with arrows indicating respiration within the gut and export of faecal pellets and associated microbes. Orange bubbles summarise microbiome‐mediated consequences for host performance (digestive help, detoxification, vitamin ...
