Plant growth promoting rhizobacteria can affect plant growth by different direct and indirect mechanisms [1]. PGPR influence direct growth promotion of plants by fixing atmospheric nitrogen, solubilizing insoluble phosphates, secreting hormones such as IAA, GAs, and Kinetics besides ACC deaminase production, which helps in regulation of ethylene. Induced systemic resistance (ISR), antibiosis, c...

in this study, the growth of two strains pseudomonas fluorescens vupf5 and p. fluorescens vupf5-1 (mutant bacterium similar to mutants of regulatory gacs/gaca system) were evaluated in the organic media. this spontaneous mutation blocked biosynthesis of the antimicrobial compounds hydrogen cyanide, phenazine and exoprotease by biocontrol strain pseudomonas fluorescens vupf5. by using organic me...

Historically, antidotal potencies of cyanide antagonists were measured as increases in the experimental LD(50) for cyanide elicited by the antidotes. This required the use of high doses of cyanide following pre-treatment with the putative antidote. Since IACUC guidelines at our institutions strongly discourage LD(50) determinations: we developed a new test paradigm that allowed for maximal surv...

cyanide is one of the major environmental pollutants in industrial wastewater. entrance of it to existence environmental contains very health hazardous. the cyanide can be removed from aqueous solutions in many ways, but most of these methods are expensive. in the present study, novel magnetic nanoparticle modified with a polydentate ligand is used to remove cyanide. the procedure is efficient ...

addition of potassium cyanide to a mixture of schiff base and lithium perchlorate afforded a-aminonitriles in high yields. addition of potassium cyanide to a methanolic solution of schiff base and phosphoric acid afforded a-aminonitriles. when the reaction mixture was refluxed it gave a-amino acids in high yields.

Ten bacterial strains that utilize cyanide (CN) as a nitrogen source were isolated from cassava factory wastewater after enrichment in a liquid media containing sodium cyanide (1 mM) and glucose (0.2% w/v). The strains could tolerate and grow in cyanide concentrations of up to 5 mM. Increased cyanide levels in the media caused an extension of lag phase in the bacterial growth indicating that th...

Background: Cyanide poisoning is frequently lethal, Because of the early onset of severe symptoms and difficulty in the diagnosis. Case: The case was a 29-year-old boy who collapsed suddenly after taking a bottle of beer in a bar. Samples, such as peripheral blood, stomach contents, bile fluid, urine and mouth swabs, were prepared using standard autopsy procedure and were subjected to analysis...
