TL;DR: Results showed that feedstocks that contained high energy density and easily degradable substrates exhibited high methane production potential and biodegradability, and a negative linear correlation between lignin content and experimental methane yield was found for lignocellulosic and manure wastes.

TL;DR: A deeper understanding of the mechanism in the bioconversion of lignocellulosic biomass during anaerobic digestion is provided and it is shown that hemicellulose was hydrolysed more quickly than cellulose, while lignin was very difficult to be digested.

Abstract: The capacity of cetyl trimethylammonium bromide to dissolve proteins in acid solution has been utilized in development of a method, called acid-detergent fiber method (ADF), which is not only a fiber determination in itself bnt also the major preparatory step in the determination of lignin. The entire procedure for determining fiber and lignin is considerably more rapid than presently published methods. Compositional studies show ADF to consist chiefly of lignin and polysaccharides. Correlations with the new fiber method and digestibility of 18 forages (r = —0.79) showed it to be somewhat superior to crude fiber (r = —0.73) in estimating nutritive valué. The correla-
