In general, the biodegradation of a toxic compound by a micro-organism requires the concurrence of, at least, two features in the biological system: first, the capability of the micro-organism to metabolize the toxic compound, and secondly, the capacity to resist its toxic effect. Pseudomonas pseudoalcaligenes CECT5344 is a bacterium used in the biodegradation of cyanide because it is capable t...

Engineering of hybrid gene clusters between the toluene metabolic tod operon and the biphenyl metabolic bph operon greatly enhanced the rate of biodegradation of trichloroethylene. Escherichia coli cells carrying a hybrid gene cluster composed of todC1 (the gene encoding the large subunit of toluene terminal dioxygenase in Pseudomonas putida F1), bphA2 (the gene encoding the small subunit of bi...

Phenol- and naphthalene-degrading indigenous Pseudomonas pseudoalcaligenes strain C70 has great potential for the bioremediation of polluted areas. It harbours two chromosomally located catechol meta pathways, one of which is structurally and phylogenetically very similar to the Pseudomonas sp. CF600 dmp operon and the other to the P. stutzeri AN10 nah lower operon. The key enzymes of the catec...

The genus Pseudomonas has been reported to be a genetically and metabolically diverse bacterial group (Anzai et al., 2000; Kersters et al., 1996; Moore et al., 1996). Pseudomonas species of the rRNA-DNA similarity group I have been previously stated by Palleroni (1984) to form the genus Pseudomonas (sensu stricto) within the g subclass of the Proteobacteria. The formerly Pseudomonas species of ...

Interactions between biotype E greenbugs, Schizaphis graminum (Rodani), and two near isogenic lines of the greenbug resistance gene Gb3 of wheat, Triticum aestivum L., were examined for 62 d after infestation. By comparing aphid performance and host responses on control and greenbug-preconditioned plants, we demonstrated that systemic resistance to greenbug herbivory was inducible in the resist...

Plant-associated microbes have specific beneficial functions and are considered key drivers for plant health. The bacterial community structure of healthy Anthurium andraeanum L. plants was studied by 16S rRNA gene pyrosequencing associated with different plant parts and the rhizosphere. A limited number of bacterial taxa, i.e., Sinorhizobium, Fimbriimonadales, and Gammaproteobacteria HTCC2089 ...

An extracellular alkaline lipase of alkalophilic Pseudomonas pseudoalcaligenes F-111 was purified to homogeneity. The apparent molecular weight determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis was 32,000, and the isoelectric point was 7.3. With p-nitrophenyl esters as its substrates, the enzyme shows preference for C12 acyl and C14 acyl groups. It was stable in the pH ran...
