تجزیه ی حشره کش دیمتوات توسط باکتری Pseudomonas Putida

  Received: 21 April, 2009 Accepted: 8 July, 2009   Abstract   Background & Aims: Dimethoate as an organophosphorus compound is commonly used for crop production which is neurotoxic in human. Pseudomonas family harbor organophosphate degrading plasmids have been known as tools for cleaning environmental pollutions.   Materials & Methods: Pseudomonas Putida was isolated from contaminated soil b...

Pathogenic significance of Pseudomonas fluorescens and Pseudomonas putida.

Among the members of the genus Pseudomonas, P. aeruginosa and P. pseudomallei were, until recently, considered the human pathogens. However, since the early 1960s, other Pseudomonas species have been found in clinical specimens, and their number and frequency of isolation seem to be growing.' The "simple fluorescent" species, P. fluorescens and P. putida, belong to those that were thought by ea...

Independent Formaldehyde Dehydrogenase Gene from Pseudomonas putida

A DNA fragment of 485 bp was specifically amplified by PCR with primers based on the N-terminal sequence of the purified formaldehyde dehydrogenase (EC 1.2.1.46) from Pseudomonas putida and on that of a cyanogen bromide-derived peptide. With this product as a probe, a gene coding for formaldehyde dehydrogenase (fdhA) in P. putida chromosomal DNA was cloned in Escherichia coli DH5ot. Sequencing ...

Aromatic acids are chemoattractants for Pseudomonas putida.

A quantitative capillary assay was used to show that aromatic acids, compounds that are chemorepellents for Escherichia coli and Salmonella sp., are chemoattractants for Pseudomonas putida PRS2000. The most effective attractants were benzoate; p-hydroxybenzoate; the methylbenzoates; m-, p-, and o-toluate; salicylate; DL-mandelate; beta-phenylpyruvate; and benzoylformate. The chemotactic respons...
