The reductive dissolution of poorly crystalline ferric oxides in the presence of cysteine was investigated to evaluate the potential of cysteine as a possible electron carrier to stimulate the reduction of iron(III) oxides by Geobacter sulfurreducens. The extent and rate of biotic and abiotic reduction of iron(III) oxides in the presence of cysteine at various concentrations were compared. Iron(III) oxides were reduced abiotically by cysteine. The initial rate and extent of iron(III) oxide…

Smectite Reduction by Shewanella Species as Facilitated by Cystine and Cysteine

It is concluded that, in the experiments, cystine and cysteine functioned as electron carrier in the smectite reduction systems, and were favorable factors influencingsmectite illitization.

Reductive dissolution of goethite and the subsequent transformation of 4-cyanonitrobenzene: Role of ascorbic acid and pH

There is a widespread interest in understanding the reactivity of organic pollutants in reducing systems. The reductive transformation of 4-cyanonitrobenzene (4-CNB) was examined in batch suspensions

Reductive Dissolution of Fe(III) (Hydr)oxides by Cysteine: Kinetics and Mechanism

Experimental data and modeling results indicated that the reductive dissolution of hydrous ferric oxide (HFO) takes place via surface complex formation of cysteine and corresponds to the rate law d[Fe(II))]/dt = k20[ identical withFecys-] + k21[ identical as well as Fecys0, respectively, where k20 and k21 are the corresponding rate constants for the cysteined surface species.

NIST Critically Selected Stability Constants of Metal Complexes Database

The Version 8.0 of the database is now a Windows application, and an effort was made to maintain the efficient "look and feel" and color schemes of the original Versions 1.0 5.0, so the previous users would not be distracted by having to learn a new interface.
