How to get 500 million years of experience in anaerobic digestion: animal mimicking

Résumé

We present an original approach which consists to analyse natural innovation in animal digestive tracts in order to improve anaerobic digestion processes. The first step of this approach consists in a large descriptive inventory of animal digestive tracts. Each digestive system can be divided in elementary steps which could be translated in terms of process engineering: cutting and grinding compartments; Continuous Stirred Tank Reactor (CSTR) or Plug Flow Reactor (PFR); chemical, enzymatic or biological reactors;and filtration press. This paper presents only few examples of animal digestive systems among the huge, mainly unknown, diversity of animal digestive systems. Two types of systems are highlighted. Firstly, we discuss on the evolution of the structures in relation to the feeding habit (carnivorous, omnivorous, granivorous, herbivorous) and secondly, the different features selected by animals in order to face the digestion of ligno-cellulosic compounds. Finally, the different elementary units of the studied digestive systems was compared and their role on the process analysed.
