Abstract

In order to increase the biogas yield of energy crops the degradation of fibrous constituents needs to be improved. In addition to mechanical and chemical procedures of treatment, more attention is given to research regarding enzymatic treatment. Therefore, efforts are concentrating on finding inexpensive sources for enzyme production. One source could be the digestive tract of herbivores which contains microorganisms and enzymes highly specialized in fibre degradation. The influence of such microorganisms and their enzymes on the degradation of maize silage has been demonstrated in anaerobic batch digestion tests using the example of rabbit faeces.
