Iron-reducing bacteria assay

Iron-reducing bacteria (IRB) are microorganisms capable of transforming ferric iron (Fe³⁺) into ferrous iron (Fe²⁺). This reduction process plays a key role in metal bioavailability, material corrosion, and biogeochemical cycles in soils and aquatic environments. These bacteria belong to genera such as Geobacter and Shewanella , and their presence strongly influences the microbiological and chemical balances of natural and industrial environments. Measuring IRB levels is essential for assessing the risks of infrastructure degradation, optimizing environmental management, and understanding microbial interactions in different ecosystems.

Analytical methods for the determination of iron-reducing bacteria

The analysis of wood chips can be carried out using several complementary approaches:

• Enumeration on specific culture medium : classic method for isolating and counting viable colonies of iron-reducing bacteria.
• PCR (Polymerase Chain Reaction) : a molecular biology technique targeting BRF-specific genetic sequences, offering rapid and sensitive detection even at low concentrations.
• DNA sequencing (NGS – Next Generation Sequencing) : a cutting-edge method for characterizing microbial diversity and identifying bacterial communities involved in iron reduction processes.

These methods, also used in other microbiological analyses, complement the classical PCR and NGS sequencing approaches used for the study of complex contaminants and microbiomes.

Industrial and environmental applications

The measurement of iron-reducing bacteria has numerous applications in various sectors:

• Materials and packaging industry : assessment of microbial corrosion in metal structures, tanks and distribution networks.
• Environment : monitoring of iron bioavailability in soils, water and sludge, as well as microbial interactions with other metals.
• Energy and geosciences : study of microbial processes in bioenergy and bioremediation.
• Scientific research : understanding the mechanisms of iron reduction and their implications in biogeochemical cycles.

This service complements other microbiological analyses such as general bacterial enumeration or detection of specific microorganisms by PCR.

Matrices analyzed for iron-reducing bacteria

YesWeLab's partner laboratories perform these analyses on various matrices: agricultural or industrial soils, groundwater, process water, sewage sludge, microbial extracts, or biofilms formed on metallic surfaces. Each type of sample requires specific preparation and an appropriate analytical method to guarantee the reliability and representativeness of the results.

Challenges of traceability and microbiological control

The presence of iron-reducing bacteria can have significant consequences: accelerated corrosion of industrial facilities, deterioration of polymer and metallic materials, changes in soil and water quality, and risks to environmental and health safety. Measuring these bacteria allows us to: anticipate biodeterioration phenomena, implement appropriate control strategies, secure infrastructure, and ensure compliance with environmental regulations. These objectives are similar to those encountered in other analyses of microbiological contamination and biocorrosion in materials and packaging.
