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

Sewage sludge composting: influence of initial mixtures on organic matter evolution and N availability in the final composts.
TL;DR: The influence of bulking agents on organic matter (OM) stability and nitrogen (N) availability in sewage sludge composts was investigated and they were removed by the screening; this induced the homogenisation of compost characteristics and led to the production of sludging composts with similar organic matter characteristics, C degradability and N availability.

TL;DR: The research provided some information regarding the effect of crop residues with N fertilizer on N2O emissions and denitrifier abundances in two soils and implies the property of crop residue and rate of N fertilizer are important influencing factors of N1O emission when crop residues combined with N fertilization are applied to different agricultural soils.

Decomposition of Phragmites australis rhizome in a shallow lake.
TL;DR: Bacteria were found to be the primary colonizers of plant detritus, which was followed by fungal growth, and an antagonistic relationship was observed between bacteria and fungi.

Fine litter chemistry, early-stage decay, and nitrogen dynamics under plantations and primary forest in Lowland Amazonia
TL;DR: One year field exposures of leaf litter from replicated plots of Pinus caribaea var. hondurensis Barrett and Golfari, Carapa guianensis Aubl., Euxylophora paraensis Hub., a Leguminosae combination (Dalbergia nigra Fr. All., Dinizia excelsa Ducke, Parkia multijuga Benth.), and adjacent upland (terra firme) forest at the Curua-Una Forest Reserve, Para, Brazil were used to examine the factors controlling leaf litter decay and N dynamics in
