Specific Methanogenic Activity (SMA)

The Specific Methanogenic Activity (SMA) can be defined as the maximum production capacity of methane by an anaerobic microbial consortium.

Anaerobic systems can demonstrate variability in their efficiency. The Specific Methanogenic Activity (SMA) test aims to evaluate the capacity of anaerobic bacteria to convert organic substrates into methane (CH4) and carbon dioxide (CO2), under previously determined and stable conditions.

Genetica Bioscience performs Specific Methanogenic Activity (SMA) analysis using state-of-the-art equipment. We are one of the few companies in the world that qualifies the biogas generated in the laboratory test for specific methanogenic activity.

To better understand the operating parameters of the reactors, sludge granulometry, acidity and alkalinity and physical-chemical analyses of the output effluent are also carried out when requested.


The results are presented in complete and easy-to-understand reports, where all parameters are presented with the ideal reference value, in addition to the weighted technical conclusion.

Below is the generation curve model and other chemical parameters of biogas:
