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

A new biological method for determining amino acid digestibility in poultry feedstuffs using a simple cannula, and the influence of dietary fibre on endogenous amino acid output
Y. Raharjo,D.J. Farrell +1 more
TL;DR: It was concluded that the appropriate site for measuring the disappearance of amino acids in feeds is the terminal ileum, and a simple glass cannula is a suitable way of collecting digesta for chemical analysis.

Solid state bioconversion of lignocellulosic residues by Inonotus obliquus for production of cellulolytic enzymes and saccharification.
TL;DR: The enzyme cocktail exhibited promising properties in terms of high catalytic activity at 40-60°C and at pH 3.0-4.5, indicating that the cellulolytic enzymes represent thermophilic and acidophilic characteristics.

Co-combustion of low rank coal/waste biomass blends using dry air or oxygen
TL;DR: In this article, the effects of the oxidizer type and the blending ratio of biomass were evaluated considering some thermal reactivity indicators such as the maximum burning rate and its temperature, the maximum heat flow temperature, and the burnout levels.

Decomposition and nitrogen release from leaves of three hardwood species grown under elevated O3 and/or CO2
TL;DR: In this paper, the effects of elevated O3 and/or CO2 on the subsequent decomposition and nutrient release from the leaves grown in such altered atmospheres, were determined by growing seedlings of three widespread North American forest trees, black cherry (Prunus serotina) (BC), sugar maple (Acer saccharum) (SM), and yellow-poplar (Liriodendron tulipifera) (YP) for two growing seasons in charcoal-filtered air (CF-air), ambient O3 (1X) or twice-amb

Changes in iron, zinc and chelating agents during traditional African processing of maize : effect of iron contamination on bioaccessibility
Valérie Greffeuille,A. P. Polycarpe Kayodé,Christèle Icard-Vernière,Muriel Gnimadi,Isabelle Rochette,Claire Mouquet-Rivier +5 more
TL;DR: Evaluation of iron bioaccessibility by in vitro enzymatic digestion followed by dialysis revealed that the iron contamination, followed by lactic acid fermentation, led to a considerable increase in bioaccessible iron content.
