    Abstract

    In the dense microbial aggregates usually found in methanogenic waste water treatment systems, hydrogen has to diffuse from producers to consumers at considerable rates. The ensuing hydrogen gradients dissipate part of the potential energy that would otherwise be available to the hydrogen-consuming organisms. The present paper evaluates the energetic consequences of this phenomenon.
