Purified catabolic ornithine carbamoyltransferase of Pseudomonas putida and anabolic ornithine carbamoyltransferase (argF product) of Escherichia coli K-12 were used to prepare antisera. The two specific antisera gave heterologous cross-reactions of various intensities with bacterial catabolic ornithine carbamoyltransferases formed by Pseudomonas and representative organisms of other bacterial ...

to evaluate the effects of phosphate solubilizing bacteria and chemical phosphorous fertilizer on turnip (brassica rapa) forage yield under limited irrigation regimes, a field experiment was conducted in research farm of college of agriculture and natural resources, university of tehran, in karaj/iran during 2009 growing season. the experimental treatments were arranged as split plots. five lev...

Abstract Nutmeg is important for national and community revenue mainly in Maluku Province where nutmeg seedlings are grown low-fertility soil without fertilizer. A greenhouse experiment was performed to evaluate the response of following application two different biofertilizer concortia. The experimental design completely randomized block design, which tested combination treatments rates method...

Contaminated phosphorus in aquatic environments is a critical problem. This research studied on removal of phosphorus from domestic wastewater by using Echinodorus cordifolius augmented with Pseudomonas putida and Flavobacterium oryzihabitans. Plants treated phosphorus from domestic wastewater for 20 test runs continuously, the effect of phosphorus treatment by microorganisms in domestic wastew...

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 cont...

A technique is described for detecting and characterizing bacteria on a single-particle basis by mass spectrometry. The method involves generation of a particle beam of single whole cells which are rapidly volatilized and ionized in vacuum in the ion source of a quadrupole mass spectrometer. The particle beam can be generated, with minimal sample handling, from a naturally occurring aerosol or ...

Aloe vera variety barbadensis is a potential alternative antimicrobial plant extract that has been widely used in humans. The objective of this study was to investigate the susceptibility selected bacterial isolates from cultured freshwater fish different concentrations crude extract. Using Minimum inhibitory concentration method by Broth dilution technique, diluted distilled water 250 mg/ml, 1...

The purpose of this study was to isolate and select indigenous soil Pseudomonas and Bacillus bacteria capable of developing multiple mechanisms of action related to the biocontrol of phytopathogenic fungi affecting soybean crops. The screening procedure consisted of antagonism tests against a panel of phytopathogenic fungi, taxonomic identification, detection by PCR of several genes related to ...
