Engineering the soil bacterium Pseudomonas putida for arsenic methylation.

چکیده
Accumulation of arsenic has potential health risks through consumption of food. Here, we inserted the arsenite [As(III)] S-adenosylmethionine methyltransferase (ArsM) gene into the chromosome of Pseudomonas putida KT2440. Recombinant bacteria methylate inorganic arsenic into less toxic organoarsenicals. This has the potential for bioremediation of environmental arsenic and reducing arsenic contamination in food.

Volatilization of Arsenic from Polluted Soil by Pseudomonas putida Engineered for Expression of the arsM Arsenic(III) S-Adenosine Methyltransferase Gene
Even though arsenic is one of the most widespread environmental carcinogens, methods of remediation are still limited. In this report we demonstrate that a strain of Pseudomonas putida KT2440 endowed with chromosomal expression of the arsM gene encoding the As(III) S-adenosylmethionine (SAM) methyltransfase from Rhodopseudomonas palustris to remove arsenic from contaminated soil. We genetically...
متن کاملComplete Genome Sequence of the p-Nitrophenol-Degrading Bacterium Pseudomonas putida DLL-E4
The first complete genome sequence of a p-nitrophenol (PNP)-degrading bacterium is reported here. Pseudomonas putida DLL-E4, a Gram-negative bacterium isolated from methyl-parathion-polluted soil, can utilize PNP as the sole carbon and nitrogen source. P. putida DLL-E4 has a 6,484,062 bp circular chromosome that contains 5,894 genes, with a G+C content of 62.46%.
متن کاملAntagonistic Potential of Mycorrhiza Associated Pseudomonas Putida against Soil Borne Fungal Pathogens
Mycorrhizal spores were found to be closely associated with bacteria on their spore wall surface known as mycorrhiza associated bacteria (MAB) and its play a major role in the plant growth promotion by production of many known and unknown metabolites, nutrient solubilization and suppression of many soil borne pathogens in rhizosphere of crop plants. The present study was carried out to understa...
متن کاملFrom dirt to industrial applications: Pseudomonas putida as a Synthetic Biology chassis for hosting harsh biochemical reactions.
The soil bacterium Pseudomonas putida is endowed with a central carbon metabolic network capable of fulfilling high demands of reducing power. This situation arises from a unique metabolic architecture that encompasses the partial recycling of triose phosphates to hexose phosphates-the so-called EDEMP cycle. In this article, the value of P. putida as a bacterial chassis of choice for contempora...

The purpose of this study was to isolate and characterize Proline Dehydrogenase (ProDH) enzyme frommicroorganisms isolated from soil in Iran. Isolation and screening of L-proline degradative enzymes from soilsamples was carried out. The isolate was characterized by biochemical markers and 16S rRNA geneanalysis. The target ProDH was purified and the effects of pH and temperatur...
