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 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 کاملRole of Fur on cyanide tolerance of Pseudomonas pseudoalcaligenes CECT5344.
Pseudomonas pseudoalcaligenes CECT5344 can be used in cyanide bioremediation processes because it grows at pH 9.5 using 2.0 mM cyanide at the sole nitrogen source. Cyanide strongly binds to metals creating iron-deprivation conditions. The bacterium responds to the presence of cyanide by inducing several processes such as siderophore synthesis for iron capture, cyanide-insensitive respiration sy...
متن کاملCyanide metabolism of Pseudomonas pseudoalcaligenes CECT5344: role of siderophores.
Cyanide is one of the most potent and toxic chemicals produced by industry. The jewelry industry of Córdoba (Spain) generates a wastewater (residue) that contains free cyanide, as well as large amounts of cyano-metal complexes. Cyanide is highly toxic to living systems because it forms very stable complexes with transition metals that are essential for protein function. In spite of its extreme ...
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...
