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

Effect of freeze-drying and heating during analysis on dietary fiber in cooked and raw carrots
TL;DR: In this article, the effects of cooking, freeze-drying, and the starch gelatinization procedure on the amount of soluble and insoluble fiber in carrots were investigated, and information was also obtained on the chemical composition of the soluble fiber from samples subjected to these treatments.

TL;DR: In this paper, the preparation and characterization of biomass-derived renewable microporous carbon nanoparticles obtained by microwave-assisted hydrothermal carbonization (MAHC), following by physical activation, of assai stone waste was also investigated.

Nitrogen release from differently aged Raphanus sativus L. nitrate catch crops during mineralization at autumn temperatures
TL;DR: The N mineralization and nitrification potential at these low soil temperatures suggest that a considerable fraction of the N captured by nitrate catch crops may be remineralized, nitrified and thus available for plant uptake but also for loss by leaching and denitrification.

Effects of high-temperature isochoric pre-treatment on the methane yields of cattle, pig and chicken manure
TL;DR: Cattle manure, dewatered pig manure and chicken manure were pre-treated in a high-temperature reactor under isochoric conditions for 15 min at temperatures between 100 and 225°C with 25% intervals to study the effect on their methane yield.

Non-symbiotic nitrogen fixation during leaf litter decomposition in an old-growth temperate rain forest of Chiloé Island, southern Chile: Effects of single versus mixed species litter
TL;DR: A strong coupling between in situ acetylene reduction and net N mineralization in surface soils is found, suggesting that as soon N is fixed by diazotroph bacteria it may be immediately incorporated into mineral soil by N mineralizers, thus reducing N immobilization.
