Hydrocarbon influence on denitrification in bioturbated Mediterranean coastal sediments [PDF]

, 1997
An in situ experiment has been carried out inbioturbated Mediterranean coastal marine sediments (Gulfof Fos) in order to study the influence of hydrocarbons ondenitrification after 1, 4 and 6 months. In theabsence of hydrocarbons in the control sediments,

Metagenomic Insights into the Abundance of Iron-Reducing Microorganisms in a Petroleum-Contaminated Iron-Rich Aquifer

Microorganisms
In petroleum-contaminated aquifers, iron (III) serves as an electron acceptor, enabling microbial degradation of organic matter. While previous studies have focused on iron reduction and organic matter degradation under laboratory conditions, research on

Agricultural By‐Products as Secondary Risk Matrices: Hazard Occurrence, Contaminant Fate, Mitigation Strategies, and Regulatory Considerations in Food Systems

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 5, September 2026.
ABSTRACT Agricultural by‐products are increasingly valorized as food ingredients within circular food systems. However, their safety cannot be directly inferred from their corresponding primary commodities. Moreover, agricultural by‐products serve as secondary risk matrices by acting as reservoirs or accumulation points for microbiological hazards ...

Red to Green: A Lipid Biomarker Record of Tonian‐Ediacaran Algae in Siberia

Geobiology, Volume 24, Issue 5, September/October 2026.
ABSTRACT Multiple lines of evidence point to a major diversification of Eukarya in the late Tonian period, ca. 800–720 Ma ago. Regular steranes, lipid biomarkers primarily sourced from eukaryotes, are first unambiguously reported from multiple sites. Here, we present lipid biomarker stratigraphic records from two drill‐cores from the Lena‐Anabar Basin ...
