Cyanide-bridged polynuclear complexes
The three mixed valent dinuclear cyanide-bridged complexes LMCNFeCl3, (LM = Cp(dppe)Fe, Cp(dppe)Ru and Cp(PPh3)2Ru) were synthesized and characterized by X-ray single crystal determination, IR, UV-Vis and cyclic voltammograms, respectively. The three mixed valent dinuclear complexes display metal- …

Engineering cyanide-tolerant Arabidopsis thaliana
Cyanide is highly toxic as it inhibits respiration in aerobic organisms by binding to cytochrome c oxidase in the mitochondrial electron transport chain. Plants naturally produce cyanide from the hydrolysis of cyanogenic glycosides and as a by-product of ethylene biosynthesis. β-Cyanoalanine …

Potassium cyanide inhibition of mixed bacterial populations
… the cell. However, the mechanism of action of cyanide is specific; cyanide irreversibly binds the iron group of cytochrome oxidase preventing transfer of electrons to oxygen. Hence, microbial sewage treatment processes may be severely disrupted by influx of cyanide bearing wastes. Cyanide …

Electrochemiluminescence of a Ruthenium Polypyridyl Cyanide Complex
… Polypyridyl ruthenium complexes containing cyanide have also been shown to have strong visible absorptions and ground and excited state properties that make them potentially useful in practical application. However, their ECL has never been reported. The electrochemiluminescence of …

Palladium-catalyzed reactions of ammonia, carbon monoxide, and cyanide
… isolation and characterization of arylpalladium cyanide complexes that undergo reductive elimination to form arylnitriles have been demonstrated. The rates of reductive elimination from a series of arylpalladium cyanide complexes reveal that the electronic effects on the reductive elimination …

EVLA imaging of methanimine and hydrogen cyanide in Arp 220
… excited($\nu_2=1$) state of hydrogen cyanide(HCN) toward the nearest Ultraluminous Infrared Galaxy, Arp 220, taken with the Expanded Very Large Array (EVLA) in A configuration. The 5289.8 MHz \meth\ line was detected in emission toward the western nucleus, but not toward the eastern …

Phytochemical Investigations of Fungi: Hydrogen-Cyanide, Indole Alkaloids and Carbohydrates
… fungal secondary metabolites including hydrogen cyanide, indole alkaloids and reserve carbohydrates were investigated. The major emphasis of this study concerned the taxonomic significance and the mechanism of HCN production by microorganisms, especially fungi.

Cyanide degradation by Bacillus pumilus C1 : cellular and molecular characterization
A cyanide-degrading, Gram-positive, aerobic, endospore-forming bacterium was isolated from a cyanide wastewater dam by an enrichment technique and was identified as a strain of Bacillus pumilus. The bacterium was routinely cultured in Oxoid nutrient broth and rapidly degraded 100 mg/1 of free …

The effect of carbonate concentration in cyanide metal plating solutions
… in copper, cadmium, silver, and gold cyanide plating solutions on the properties of the deposits and the plating range. A 267 milliliter Hull cell was used to investigate this problem. By using this apparatus the concentration of carbonate could be readily changed, and the effect which …

The Toxicokinetic Behavior of Cyanide, Thiocyanate and 2-Amino-2-Thiazoline-4-Carboxylic Acid Following Cyanide Exposure in Multiple Animal Models Utilizing Novel Methods of Detection
<p>Humans may be exposed to cyanide (CN-), a highly toxic chemical, by a number of means, such as consumption of cyanogenic plants (e.g., cassava, sorghum, lima beans, etc.), vehicle exhaust, cigarette smoke, or accidental exposure during industrial operations, such as plastic and paint processing, …

Requirements for Cell-Free Cyanide Oxidation by Pseudomonas Fluorescens NCIMB 11764
The involvement of cyanide oxygenase in the metabolism of pyruvate and a-ketoglutarate-cyanohydrin was investigated and shown to occur indirectly by the consumption of free cyanide arising from the cyanohydrins via chemical dissociation. Thus, free cyanide remains the substrate, for which the …
