Microbial Analyses for Biogas Digesters

Microorganisms are essential for biogas production: Some digest the substrate ingredients, others generate Methane.

With our analyses of the microbiology of biogas digesters it is possible to optimize the microbial composition and thus enhance performance and robustness of biogas production. This allows to identify the present pathway of methanogenesis (acetoclastic/hydrogenotrophic) as well as bottlenecks. A monitoring can detect upcoming problems earlier than classical methods.

More information about microorganisms in biogas digesters, and how microbial analysis and the C4S rule help to control biogas digesters may be found here.

Elementary Molecular Characterisation of Biogas Digesters

This service offers a screening analysis of Methanogens including their Shannon index and DNA concentration.

Detailed Molecular Characterisation of Biogas Digesters

Comprehensive Molecular Characterisation of Biogas Digesters

This service extends the detailed molecular characterisation with the so-called “ASG-Syntrophics”. These special bacteria are key players for the hydrogenotrophic methanogenesis.

Selected Molecular Characterisation of Biogas Digesters

Absolute Quantification of Methanogenic Archaea and Bacteria

Measuring the DNA concentration for two groups of microorganisms: Methanogenic archaea and total bacteria.

Absolute Quantification of Methanogenic Archaea, Bacteria and ASG Syntrophics

Measuring the DNA concentration for three groups of microorganisms: methanogenic archaea, total bacteria and the group of so-called “ASG Syntrophics”.

Absolute Quantification of Methanoculleus sp.

Species of genus Methanoculleus are presumed to be highly efficient methane producers.

Absolute Quantification of Sulfate-reducing Bacteria

Sulfate-reducing Bacteria (SRB) compete with methanogenic archaea for the hydrogen.
