Utilization of cyanide as a nitrogen source by Pseudomonas fluorescens NCIMB 11764 occurs via oxidative conversion to carbon dioxide and ammonia, with the latter compound satisfying the nitrogen requirement. Substrate attack is initiated by cyanide oxygenase (CNO), which has been shown previously to have properties of a pterin-dependent hydroxylase. CNO was purified 71-fold and catalyzed the qu...

The toxicity of cyanide in water, air and soil is an excepted fact. However to find serious exposure limits is a difficult task. Data for the evaluation is often old and difficult to use in contemporary requirements, on the other hand, studies about the toxicity of cyanide are getting more complicated due to the growing knowledge of its hazardousness. One of the basic arguments for the definiti...

Illegal cyanide fishing is practiced by some fishers to capture agile and otherwise inaccessible reef fishes easily. Economic incentives had prevented discontinuation of the practice despite regulations present. Aside from well-known toxicity cyanide, it a concern whether fish for ornamental purposes or human consumption that being used because environmental damage can cause killing off non-tar...

The oxidative metabolic potential of Setaria digitata, a filarial parasite found in the intraperitoneal cavity of cattle, was investigated. These worms showed active wriggling movements which were not affected by respiratory poisons such as cyanide, rotenone and malonate. They also possessed cyanide-insensitive and glucose-independent oxygen consumption pathways. By differential centrifugation ...

water resource scarcity, population growth, pollution of surface and groundwater by discharging toxic wastewater and subsequent diseases may raise the necessity of reusing and treatment of wastewater. cyanide is one of the toxic materials which can be found in some industrial wastewaters. strict laws set by international bodies have forced industries to work on developing efficient cyanide remo...
