Co-cultured methanogen improved the metabolism in the hydrogenosome of anaerobic fungus as revealed by gas chromatography-mass spectrometry analysis.

The co-culture of the anaerobic fungus and the methanogen is a good model for studying the microbial interaction between H2-producing and H2-utilizing microorganisms. However, metabolism in hydrogenosome needs to be further studied to gain better insight in the hydrogen transfer among microorganisms.
