Nitrogen and sulphur management: challenges for organic sources in temperate agricultural systems [PDF]
, 2005 A current global trend towards intensification or specialization of agricultural enterprises has been accompanied by increasing public awareness of associated environmental consequences. Air and water pollution from losses of nutrients, such as nitrogen (

Anaerobic Decomposition of Glutathione in Aqueous Solution
Journal of the agricultural chemical society of Japan, 1973 還元型グルタチオン水溶液の嫌気的分解について検討した. 水溶液はpH5.5～7.5の間で最も安定であり,加水分解反応にみられるごときpH-profileを示す.ヨウ素法による定量とo-フタルアルデヒド螢光法による定量結果から,還元力を失わずに分解が進行することがわかった.分解物中のH2Sの生成は, pH7.5以下においては全分解量に対して2%以下である.分解速度は初濃度に影響され,初濃度が増大するにしたがって速くなり,分子間相互作用のあることを示した. ペーパークロマトグラフィー,ガスクロマトグラフィー等によって,分解物としてピログルタミン酸とシステイニルーグリシンが検出され,グルタチオンの各構成アミノ酸であるグルタミン酸,グリシン,システインおよびシスチンは検出されなかった.また ...

Biochemistry Changes That Occur after Death: Potential Markers for Determining Post-Mortem Interval [PDF]
, 2013 Death is likely to result in very extensive biochemical changes in all body tissues due to lack of circulating oxygen, altered enzymatic reactions, cellular degradation, and cessation of anabolic production of metabolites.

Boosting landfill gas production from lignin-containing wastes via termite hindgut microorganism. [PDF]
, 2020 Lignocellulose comprises a significant portion of municipal solid waste (MSW) - 40-70% in developed countries, including paper, wood, and yard waste. Cellulose and hemicellulose are often shielded by lignin, posing a barrier to waste decomposition and ...

Anaerobic microsites have an unaccounted role in soil carbon stabilization
Nature Communications, 2017 Mechanisms controlling soil carbon storage and feedbacks to the climate system remain poorly constrained. Here, the authors show that anaerobic microsites stabilize soil carbon by shifting microbial metabolism to less efficient anaerobic respiration and ...

Kinetic studies on decomposition of glutathione. II. Anaerobic decomposition in aqueous solution.
Chemical and Pharmaceutical Bulletin, 1980 Kinetics studies were performed on the non-enzymatic decomposition of glutathione (GSH) in anaerobic aqueous solution. The apparent first-order rate constants of decomposition were determined in the pH range of 1-12, ionic strength 0.5, at 60° and the pH profile was constructed from the buffer-free rate constants and pH values. The decomposition of GSH
