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-

An Analysis of the Energy Potential of Anaerobic Digestion of Agricultural By-Products and Organic Waste

TL;DR: B batch trials under mesophilic conditions were conducted to evaluate the potential biogas yield of many agricultural by-products, including maize stalks, rice chaff, wheat straw, kiwi fruit, onions, and two expired organic waste products from the retail mass-market.

Digestibility of waste aerobic granular sludge from a full-scale municipal wastewater treatment system

TL;DR: Comparisons with the anaerobic conversion of waste activated sludge as well as primary sludge from full-scale municipal wastewater treatment plants indicated that compared to WAS, the proteins and carbohydrates in AGS-RTC were both more resistant to an aerobic bio-degradation, which might be related to the presence of refractory microbial metabolic products in AGs-R TC.

Carbon mineralization of leaves from four Ethiopian agroforestry species under laboratory and field conditions

TL;DR: Investigation of differences in C mineralization parameters related to differences in the leaf qualities of the respective species and effects of amending soil with leaves plus N, P, or N + P on decomposition and microbial activity found the quality of the leaves was more influential than the nutrient additions.

Improvement of methane production from greenhouse residues: Optimization of thermal and H2SO4 pretreatment process by experimental design

TL;DR: In this article, the Plackett-Burman design (PBD) combined with central composite design (CCD) was employed for the optimization of thermal-H2SO4 pretreatment of greenhouse residues to obtain maximum biochemical methane potential (BMP).

Nitrogen cycling associated with the decomposition of sunflower stalks and wheat straw in a Vertisol.

TL;DR: In this paper, C mineralization and N transformations during the decomposition of sunflower stalks (Helianthus annuus L) and wheat straw (Triticum aestivum L) with and without addition of (NH4)2SO4 (2753 atom% 15N) were studied in a Vertisol Soil sample for 224 days at 22 °C.
