Pseudomonas pseudoalcaligenes CECT5344, a cyanide-degrading bacterium with by-product (polyhydroxyalkanoates) formation capacity
BACKGROUND Cyanide is one of the most toxic chemicals produced by anthropogenic activities like mining and jewelry industries, which generate wastewater residues with high concentrations of this compound. Pseudomonas pseudoalcaligenes CECT5344 is a model microorganism to be used in detoxification of industrial wastewaters containing not only free cyanide (CN(-)) but also cyano-derivatives, such...
متن کاملDegradation of soil cyanide by single and mixed cultures of Pseudomonas stutzeri and Bacillus subtilis.
The aim of this investigation was to study whether certain bacteria could be used for cyanide degradation in soil. The bacteria Pseudomonas stutzeri and Bacillus subtilis were selected based on their good growth in a minimal medium containing 0.8 mg mL-1 potassium cyanide (KCN). In this study we tested their ability to reduce cyanide levels in a medium containing 1.5 mg mL-1 of KCN. Although bo...
متن کاملAlkaline cyanide biodegradation by Pseudomonas pseudoalcaligenes CECT5344.
Pseudomonas pseudoalcaligenes CECT5344 uses cyanide, cyanate, beta-cyanoalanine, and other cyanoderivatives as nitrogen sources under alkaline conditions, which prevents volatile HCN (pK(a) 9.2) formation. The cyanide consumed by this strain is stoichiometrically converted into ammonium. In addition, this bacterium grows with the heavy metal, cyanide-containing waste water generated by the jewe...

متن کاملPseudomonas aeruginosa and cyanide production.
I nfection and subsequent chronic infection of the cystic fibrosis (CF) lung with organisms such as Pseudomonas aeruginosa probably occurs at an early stage in the life of a child suffering from CF. Clinicians worldwide are eager to isolate the organism as early as possible in an attempt to treat the patient before any permanent damage occurs and hopefully to eliminate the organism completely f...
