Bacterial degradation of cyanide and its metal complexes under alkaline conditions.
A bacterial strain able to use cyanide as the sole nitrogen source under alkaline conditions has been isolated. The bacterium was classified as Pseudomonas pseudoalcaligenes by comparison of its 16S RNA gene sequence to those of existing strains and deposited in the Coleccion Espanola de Cultivos Tipo (Spanish Type Culture Collection) as strain CECT5344. Cyanide consumption is an assimilative p...
متن کاملCo-metabolism of thiocyanate and free cyanide by Exiguobacterium acetylicum and Bacillus marisflavi under alkaline conditions
The continuous discharge of cyanide-containing effluents to the environment has necessitated for the development of environmentally benign treatment processes that would result in complete detoxification of the cyanide-containing wastewaters, without producing additional environmental toxicants. Since biological detoxification of hazardous chemical compounds has been renowned for its robustness...
متن کاملDegradation of the metal-cyano complex tetracyanonickelate(II) by cyanide-utilizing bacterial isolates.
Ten bacterial isolates capable of growth on tetracyanonickelate(II) [K2[Ni(CN)4]] (TCN) as the sole nitrogen source were isolated from soil, freshwater, and sewage sludge enrichments. Seven of the 10 were identified as pseudomonads, while the remaining 3 were classified as Klebsiella species. A detailed investigation of one isolate, Pseudomonas putida BCN3, revealed a rapid growth rate on TCN (...
متن کاملBacterial cyanide degradation is under review: Pseudomonas pseudoalcaligenes CECT5344, a case of an alkaliphilic cyanotroph.
There are thousands of areas in the U.S.A. and Europe contaminated with cyanide-containing wastes as a consequence of a large number of industrial activities such as gold mining, steel and aluminium manufacturing, electroplating and nitrile pesticides used in agriculture. Chemical treatments to remove cyanide are expensive and generate other toxic products. By contrast, cyanide biodegradation c...
متن کاملEFFECTS OF SOME NOVEL ASCORBIC ACID-METAL COMPLEXES ON SELECTED BACTERIAL AND FUNGAL SPECIES
The antimicrobial activity of some novel ascorbic acid-metal complexes [bisascorbate complexes of copper (II), zinc(II), manganese (11), iron (111), cobalt(II), lead(II) and cadmium(II)] was investigated. Four standard strains of bacterial species - Staphylococcus aureus, Escherichia coli, Bacillus subtilis and Klebsiella pneumonia and four fungal species - Trichophyton sp. Penicillium sp....
