Cyanide is a toxic compound widely used in mining and jewelry industries, as well as in the synthesis of many different chemicals. Cyanide toxicity derives from its high affinity for metals, which causes inhibition of relevant metalloenzymes. However, some cyanide-degrading microorganisms like the alkaliphilic bacterium <i>Pseudomonas pseudoalcaligenes</i> CECT5344 may detoxify hazardous industrial wastewaters that contain elevated cyanide and metal concentrations. Considering that iron availabi ...[more]

Regulatory non-coding sRNA in response to cyanide in Pseudomonas pseudoalcaligenes CECT5344

Project description:Biological treatments to degrade cyanide are a powerful technology for cyanide removal from industrial wastewaters. It has been previously demonstrated that the alkaliphilic bacterium Pseudomonas pseudoalcaligenes CECT5344 is able to use free cyanide and several metal-cyanide complexes as the sole nitrogen source. In this work, the strain CECT5344 has been used for detoxification of the different chemical forms of cyanide that are present in alkaline wastewaters from the jewelry industry. This liquid residue also contains large concentrations of metals like iron, copper and zinc, making this wastewater even more toxic. To elucidate the molecular mechanisms involved in the bioremediation process, a quantitative sRNA sequencing analysis has been carried out in P. pseudoalcaligenes CECT5344 cells grown with the jewelry residue, free cyanide and ammonium as sole nitrogen sources.

Quantitative proteomic analysis (LC-MS/MS) of Pseudomonas pseudoalcaligenes CECT5344 in response to industrial cyanide-containing wastewaters

Project description:Biological treatments to degrade cyanide have shown to be a powerful technology for cyanide removal from industrial wastewaters. It has been previously demonstrated that the alkaliphilic bacterium Pseudomonas pseudoalcaligenes CECT5344 is able to use free cyanide and several metal−cyanide complexes as the sole nitrogen source. The strain CECT5344 has been used for detoxification of the different chemical forms of cyanide that are present in alkaline wastewaters from the electroplating process of the jewelry industry. This liquid residue also contains large concentrations of metals like iron, copper and zinc, making this wastewater even more toxic. A proteomic analysis by LC-MS/MS has been applied to elucidate the molecular mechanisms involved in this bioremediation process in P. pseudoalcaligenes CECT5344. Among others, different proteins related to cyanide and cyanate assimilation, as well as other proteins involved in transport and resistance to metals were induced by the cyanide-containing jewelry residue have been identified.

Global Transcriptional Response of Nitrosomonas europaea to Cyanide

Project description:Pure cultures of ammonia oxidizing bacterium, Nitrosomonas europaea, are exposed to cyanide in pseudo-steady state batch reactor in presence of ammonia. Nitrosomonas europaea are generally regarded as the most sensitive organism to various inhibitors commonly encountered in the wastewater treatment plants (WWTP). To find stress genes of Nitrosomonas europaea to cyanide known as inhibitor of respiratory process, whole-genome transcript response to cyanide was determined in this research using microarray and qRT-PCR. When 1 uM NaCN inhibits nitrification about 50 %, transcript levels of 35 genes were increased while transcript levels of 29 genes were decreased, showing more than 2-fold in total 2460 genes. moeZ (NE2353), homologue with rhodanases related to detoxification of CN-, showed 7-fold up regulation and gene cluster including moeZ also showed significant up regulation. Keywords: cyanide, stress response, moeZ
