To determine the most useful diagnostic characters for the differentiation of pseudomonads pathogenic for man, including Pseudomonas maltophilia (Alcaligenes bookeri), P. stutzeri (Bacillus denitrificans), P. pseudomallei (Malleomyces pseudomallei), and apyocyanogenic strains of P. aeruginosa, a comparative examination was made of 58 strains of these bacilli for their morphological and biochemi...

Soil salinization is increasing steadily in many parts of the world and causes major problems for plant productivity. Under these stress conditions, root-associated beneficial bacteria can help improve plant growth and nutrition. In this study, salt-tolerant bacteria from the rhizosphere of Uzbek wheat with potentially beneficial traits were isolated and characterized. Eight strains which initi...

The amino acid sequence of the cytochrome c' from Alcaligenes sp. N.C.I.B. 11015 (Iwasaki's ;Pseudomonas denitrificans') has been determined. This organism is the only non-photosynthetic bacterium in which the protein has been found. The protein consists of a single polypeptide chain of 127 residues, with a single haem covalently attached to two cysteines. Unlike normal cytochromes c, the haem ...

Nowadays, large areas of agricultural land are contaminated with chemical plant-protection products. Agricultural soils also susceptible to oil pollution as a result accidents on pipelines. Bioremediation such from the help hydrocarbon-oxidizing bacteria is hindered by presence additional pollutants herbicides. In this work, seven strains Pseudomonas were isolated and identified, which showed d...

The extraction of the exopolymeric matrix is a prerequisite to properly assessing the composition of the biofilm. Several extraction methods have already been developed, however, no universal method has yet been adopted because the compromise between high yields of extraction and minimum cell lysis is difficult to establish. In fact, most of the extraction methods promote leakage of intracellul...

The acetoacetyl-CoA reductase and the polyhydroxyalkanoate (PHA) synthase from Ralstonia eutropha (formerly Alcaligenes eutrophus) were expressed in Escherichia coli, Klebsiella aerogenes, and PHA-negative mutants of R. eutropha and Pseudomonas putida. While expression in E. coli strains resulted in the accumulation of poly(3-hydroxybutyrate) [PHB], strains of R. eutropha, P. putida and K. aero...

The host range of coliphage Mu was greatly expanded to various genera of gram-negative bacteria by using the hybrid plasmic RP4::Mu cts, which is temperature sensitive and which confers resistance to ampicillin, kanamycin, and tetracycline. These drug resistance genes were transferred from Escherichia coli to members of the general Klebsiella, Enterobacter, Citrobacter, Salmonella, Proteus, Erw...

Background: Bacterial endophytes lives in internal tissues of root, stem and leaves grain amaranth plants. Isolation screening efficient bacterial for plant growth promotion, biocontrol activities drought tolerance can develop as suitable bioinoculants alleviate stress promotion. Methods: were isolated from (Amaranthus spp) all isolates screened nitrogen fixation, phosphorous solubilisation, ho...
