Dynamic of sulphate-reducing microorganisms in petroleum-contaminated marine sediments inhabited by the polychaete Hediste diversicolor

, 2015
cited By 1International audienceThe behaviour of sulphate-reducing microbial community was investigated at the oxic–anoxic interface (0–2 cm) of marine sediments when submitted to oil and enhanced bioturbation activities by the addition of Hediste ...

Microbiologically influenced corrosion in aluminium alloys and premier techniques for comprehensive identification and characterization across diverse metal types

Journal of Chemical Technology &Biotechnology, Volume 100, Issue 6, Page 1143-1158, June 2025.
Abstract Microbiologically influenced corrosion (MIC) is acknowledged as a significant type of corrosion due to its extensive impact on metal/alloy surfaces. As MIC accounts for 20% of all corrosion instances, it is a critical factor causing service failure of engineering materials such as steel and aluminium alloy.

Novel taxa of Acidobacteriota implicated in seafloor sulfur cycling [PDF]

, 2021
Acidobacteriota are widespread and often abundant in marine sediments, yet their metabolic and ecological properties are poorly understood. Here, we examined metabolisms and distributions of Acidobacteriota in marine sediments of Svalbard by functional ...

New Dimensions in Microbial Ecology—Functional Genes in Studies to Unravel the Biodiversity and Role of Functional Microbial Groups in the Environment

Microorganisms, 2016
During the past decades, tremendous advances have been made in the possibilities to study the diversity of microbial communities in the environment. The development of methods to study these communities on the basis of 16S rRNA gene sequences analysis ...

Large Filamentous Bacteria Isolated From Sulphidic Sediments Reveal Novel Species and Distinct Energy and Defence Mechanisms for Survival

Environmental Microbiology, Volume 27, Issue 3, March 2025.
In this study, we used micromanipulation and omics to analyse 15 large filamentous bacteria collected from sulphidic sediments off Chile. We discovered novel species from various phyla, and diverse metabolic pathways and defence mechanisms were identified, highlighting their adaptability to the sediment–water interface and resilience against phage ...

Evidence for corrin biosynthesis in the last universal common ancestor

The FEBS Journal, Volume 292, Issue 4, Page 827-850, February 2025.
Cobalamin biosynthesis can be traced back to the last universal common ancestor. After a stage of chemical evolution of the acetyl‐CoA pathway, the enzymatic synthesis of cobalamin evolved, allowing life to be independent of the insoluble solid‐state catalysts that tethered primordial CO2 assimilation to the Earth's crust, suggesting a role for corrin ...

Deciphering microbial communities involved in marine steel corrosion using high‐throughput amplicon sequencing

Environmental Microbiology Reports, Volume 16, Issue 4, August 2024.
Aggressive forms of intertidal steel corrosion are shown to involve complex microbial consortia including sulfate‐reducing, sulfide‐oxidizing and iron‐oxidizing bacteria along with others including electroactive microbes. Statistical analysis shows the populations are derived from local bed sediment, indicating sediment anoxia as a risk factor for ...

Influence of minor hydrocarbon seepage on sulfur cycling in marine subsurface sediments [PDF]

Biogeosciences
All hydrocarbon (HC) reservoirs leak to some extent. When small quantities of HCs escape offshore reservoirs and migrate through overlying organic-poor marine sediments towards the surface, these HCs are often completely metabolized by microorganisms ...
