Use of Detergents in the Analysis of Fibrous Feeds. II. A Rapid Method for the Determination of Fiber and Lignin
TLDR
The acid-detergent fiber method (ADF) as mentioned in this paper is a fiber method based on cetyl trimethylammonium bromide to dissolve proteins in acid solution.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-read more

Significance of organic nitrogen uptake from plant residues by soil microorganisms as affected by carbon and nitrogen availability
TL;DR: In this article, a microcosm experiment was carried out to determine the importance of the direct route, and the results indicated that in contrast to what is proposed by many models of soil N cycling, both the direct and MIT routes were operative, with the direct pathway being the preferred route of residue N uptake.

Decomposition of dominant plant species litter in a semi-arid grassland
TL;DR: Investigation of dominant plant species in a natural semi-arid grassland to nutrient cycling through their litter decomposition found Chrysopogon and Festuca by being the most dominant species in the grassland and having low decomposition rates contribute more organic matter to the soil.

Effect of biological pretreatment with Trametes hirsuta yj9 on enzymatic hydrolysis of corn stover
TL;DR: In this paper, Trametes hirsuta yj9 was used to pretreat corn stover in order to enhance enzymatic digestibility, and the results showed that sugar yields were inversely proportional to the lignin contents.

High-performance liquid chromatography of water-soluble phenolics in leaf litter of three Eucalyptus hybrids (Congo)
TL;DR: Leaf litter from beneath three Eucalyptus hybrids of economic importance for Congo were examined for water-soluble phenolics and E. urograndis had lower concentrations of gallic acid, but higher hydroxycinnamic acids (p-coumaric, caffeic, and ferulic acids) than the E. PF1 hybrid.

Fungal solid state culture of palm kernel cake.
TL;DR: Fungal culturing of PKC brought about an increase in the level of unsaturated- and a decrease in thelevel of the saturated-fatty acids, which affected amino acid, fatty acid, cellulose and hemicellulose fractions.
