This paper presents the results of fractionation of particulate and soluble organic matter in a mixture of maize silage and cattle manure (49:51% volatile solids) that was used as a feedstock for anaerobic digestion. The extended Weender's analysis was adapted to measure raw protein, raw lipids, fraction of carbohydrates (including starch, cellulose, hemicelluloses) and lignin. The content of individual fractions in composite, X-c (as kg COD kg(-1) COD) was: 0.111 proteins, 0.048 lipids, 0.500 carbohydrates and 0.341 inerts. The biodegradability of X-c was 68%. Based on material balance, the carbon concentration in X-c was 0.0326 kmol C kg(-1) COD, whereas nitrogen concentration 0.0018 kmol N kg(-1) COD. The estimated pH of the feedstock based on acid-base equilibrium corresponded to the actual value (pH 7.14).
