Comparison of Nitrate and Perchlorate in Controlling Sulfidogenesis in Heavy Oil-Containing Bioreactors

open access: yesFrontiers in Microbiology, 2018
Control of microbial reduction of sulfate to sulfide in oil reservoirs (a process referred to as souring) with nitrate has been researched extensively.

Spherulite in the modern aragonitic travertine stromatolite has a calcite core with exopolymers

open access: yesSedimentology, EarlyView.
ABSTRACT Spherulites are spherical to ellipsoidal particles formed by various crystalline substances and can be abiotically synthesised in the laboratory. Among various spherulite types, spherulites composed of calcium carbonate are also found in various natural environments, but their abiotic or biotic origins are still controversial.

Microbial aspects of anaerobic methane oxidation with sulfate as electron acceptor [PDF]

open access: yes, 2009
Anaerobic oxidation of methane (AOM) is an important methane sink in the ocean but the microbes responsible for AOM are as yet resilient to cultivation.

Effect of Surface Free Energy and Electrochemical Polarization on Attachment of Sulfate Reducing Bacteria [PDF]

open access: yes, 2011
Sulfate reducing bacteria (SRB) were most common bacteria involved in microbiologically influenced corrosion (MIC). In this paper, the influences of surface free energy and electrochemical polarization on sulfate reducing bacteria (SRB) attachment were ...

Effects of Sulfate Reducing Bacteria on Corrosion of Carbon Steel Q235 in Soil-Extract Solution

open access: yesInternational Journal of Electrochemical Science, 2012
Effects of sulfate reducing bacteria on corrosion of the carbon steel Q235 have been investigated in soil-extract solutions (SES). The results show that SRB dramatically decreases the corrosion rate of the carbon steel due to the reason that SRB ...

Corrosion and Degradation of Materials in Marine Environments: Implications for Coastal and Offshore Infrastructure

open access: yesEngineering Reports, Volume 8, Issue 7, July 2026.
This study presents a failure‐oriented analysis of corrosion in marine infrastructure, linking degradation mechanisms to crack initiation, fatigue propagation, and structural failure. A unified framework is proposed to connect environmental exposure, material degradation, and reliability, supporting failure prediction, inspection planning, and life ...

An update on the landscape of collagen bioactive fragments

open access: yesThe FEBS Journal, Volume 293, Issue 13, Page 4064-4084, July 2026.
The remodeling of the extracellular matrix releases collagen bioactive fragments, which exert molecular functions and regulate numerous biological processes via several signaling pathways. Here, we summarize the latest findings describing the roles of major bioactive fragments from collagens I, IV, VI, and XVIII in various physiological and ...

Update of the list of qualified presumption of safety (QPS) recommended microbiological agents intentionally added to food or feed as notified to EFSA 24: Suitability of taxonomic units notified to EFSA until March 2026

open access: yesEFSA Journal, Volume 24, Issue 7, July 2026.
Abstract The Qualified Presumption of Safety (QPS) process was developed to provide a harmonised safety assessment approach to support EFSA Scientific Panels and Units. The QPS approach assesses the taxonomic identity, body of knowledge and safety of microorganisms intentionally added to the food and feed chain.

Bioelectrical corrosion of iron by lithotrophic sulfate-reducing bacteria [PDF]

open access: yes, 2012
Iron, a technological material of prime importance, deteriorates by interaction with its abiotic and biotic environment. While the corrosion of iron in oxic environments is, to our present knowledge, a largely chemical (abiotic) process, corrosion in ...

Use of sulfate-reducing bacteria and different organic fertilizer for bioremediation of ex-nickel mining soils

open access: yesPrzegląd Naukowy Inżynieria i Kształtowanie Środowiska, 2022
The microbiological activity associated with exmining soil remediation can be considered useful to accelerate the contaminant degradation. The use of sulfate-reducing bacteria (SRB) and organic matter exhibits potential in improving ex-nickel mining soil
