Unlocking the Hidden World of Microbes: key players in Anaerobic Digestion

New core microbiome discovered

One of the most exciting findings was the discovery of a core group of microbes that we found in each of the 80 digesters, playing an essential role in the production of green gas. This core microbiome consists of MBA03, Proteiniphilum, a non-cultured organism from the Dethiobacteraceae family and a member of the Caldicoprobacter family.

In particular, we have uncovered the important contribution of MBA03, an order of bacteria that has been largely unknown until now. It is key to improving the robustness of digestion processes by providing an alternative pathway for the conversion of acetate to methane. It may even play an important role in the hydrolysis of solid substrates. We have named this group ‘Darwinibacteriales’ after Charles Darwin, the founding father of the theory of evolution

Practical relevance

But why is this relevant? Well, these findings have huge implications for improving anaerobic digestion, which is used to break down waste and produce green energy. By understanding which microbes are crucial and how they are affected by factors such as temperature, the type of digester and the material being processed, we can make anaerobic digestion more robust, efficient and environmentally friendly.

In other words, our research is helping us to better understand how nature's smallest helpers can further improve our waste management and energy production. Follow us as we continue to unlock the hidden world of microbes and their role in shaping our world!
