Project description:M. oryzae 70-15 was treated with multiple bacteria which inhibit 70-15's growth. The bacterial treatments were EA105, a pseudomonad naturally isolated from rice soil, as well as P. fluorescens biocontrol strain CHAO and the cyanide non-producing mutant of CHAO, CHA77.

Project description:Smoke inhalation from a structure fire is a common route of cyanide poisoning in the U.S. Cyanide inhibits cellular respiration, often leading to death. Its rapid distribution throughout the body can result in injuries to multiple organs, and cyanide victims were reported to experience myocardial infarction and other cardiac complications. We performed oligonucleotide microarrays to establish cardiac transcriptomes of an animal model of nose-only inhalation exposure to hydrogen cyanide (HCN), which is relevant to smoke inhalation. We also profiled cardiac transcriptomes after subcutaneous injection of potassium cyanide (KCN). Although the KCN injection model has been often used to evaluate medical countermeasures, this study demonstrated that cardiac transcriptomes are largely different from that of the HCN inhalation model at multiple time points within 24 hours after exposure.

Project description:M. oryzae 70-15 was treated with multiple bacteria which inhibit 70-15's growth. The bacterial treatments were EA105, a pseudomonad naturally isolated from rice soil, as well as P. fluorescens biocontrol strain CHAO and the cyanide non-producing mutant of CHAO, CHA77. On a standard petri dish with solid complete medium, a 5 mm plug of M. oryzae 70-15 was placed 4 cm from a 5 uL droplet of bacteria (1 X 10 ^ 6 cells per mL)

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.

Project description:Cyanide is stoichiometrically produced as a co-product of the ethylene biosynthesis pathway, and it is detoxified by the b-cyanoalanine synthase enzyme. The molecular and phenotypical analysis of T-DNA insertional mutants of the mitochondrial b-cyanoalanine synthase CYS-C1 suggests that discrete accumulation of cyanide is not toxic for the plant and does not alter mitochondrial respiration rates, but does act as a strong inhibitor of root hair development. The cys-c1 null allele is defective in root hair formation and accumulates cyanide in root tissues. The root hair defect is phenocopied in wild type plants by the exogenous addition of cyanide to the growth medium and is reversed by the addition of hydroxocobalamin. Hydroxocobalamin not only recovers the root phenotype of the mutant, but also the formation of ROS at the initial step of the root hair tip. Transcriptional profile analysis of the cys-c1 mutant reveals that cyanide accumulation acts as a repressor signal for several genes encoding enzymes involved in cell wall rebuilding and the formation of the root hair tip, as well as genes involved in ethylene signaling and metabolism. Our results demonstrate that mitochondrial b-cyanoalanine synthase activity is essential to maintain a low level of cyanide for proper root hair development.

Project description:Transcriptional analysis of the cyanotroph Pseudomonas pseudoalcaligenes CECT5344 in response to cyanide present in wastewaters from industrial activities, such as jewelry and electroplating activities Four-conditions experiment, including three different nitrogen sources (ammonium, sodium cyanide or a cyanide-containing wastewater). One experiment without nitrogen added to the media (nitrogen limited condition). Four biological replicates for each condition (added nitrogen source to the media) plus the experiment without nitrogen source added.

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.

Project description:Zebrafish embryos are significantly more resistant to cyanide exposure at 24 h post fertilization than at 7 days post fertilization. In this experiment we examined the transcriptional response to cyanide exposure at both ages.
