Structure of the O-specific polysaccharides of Pseudomonas chlororaphis subsp. chlororaphis UCM B-106

Carbohydrate Research, 2016
O-specific polysaccharide was obtained from the lipopolysaccharide of Pseudomonas chlororaphis subsp. chlororaphis UCM B-106 and studied by composition analysis along with 1D and 2D (1)H and (13)C NMR spectroscopy. The polysaccharide was found to contain a derivative of pseudaminic acid (Pse) and the following structure of the trisaccharide repeating ...

Characterization of a Homogentisate Dioxygenase Mutant in Pseudomonas chlororaphis O6

Current Microbiology, 2007
Transposon mutagenesis of Pseudomonas chlororaphis O6 was performed with the transposon Tn5 to investigate genes involved in production of secondary metabolites. A mutant, termed Org, produced intense dark-brown pigmentation on rich medium. The Tn5-flanking sequence of the Org mutant showed high homology with the hmgA gene encoding the enzyme ...

Structure and expression of gene vfr in Pseudomonas chlororaphis 449

Russian Journal of Genetics, 2009
Gene vfr previously described only in Pseudomonas aeruginosa was cloned, identified, and sequenced in cells of Pseudomonas chlororaphis 449; its localization in the chromosome was determined. Amino acid sequence of the protein encoded by gene vfr in P. chlororaphis 449 was shown to have a 83% identity with the Vfr protein of P. aeruginosa PAO1 and a 63%

Enhanced production of 2-hydroxyphenazine in Pseudomonas chlororaphis GP72

Applied Microbiology and Biotechnology, 2010
Pseudomonas chlororaphis GP72 is a root-colonizing biocontrol strain isolated from the green pepper rhizosphere that synthesizes two phenazine derivatives: phenazine-1-carboxylic acid (PCA) and 2-hydroxyphenazine (2-OH-PHZ). The 2-OH-PHZ derivative shows somewhat stronger broad-spectrum antifungal activity than PCA, but its conversion mechanism has not

Dirhamnose-lipid production by recombinant nonpathogenic bacterium Pseudomonas chlororaphis

Applied Microbiology and Biotechnology, 2015
We previously discovered that Pseudomonas chlororaphis NRRL B-30761 produces monorhamnolipids (R1Ls) with predominantly 3-hydroxydodecenoyl-3-hydroxydecanoate (C12:1-C10) or 3-hydroxydodecanoyl-3-hydroxydecanoate (C12-C10) as the lipid moiety under static growth conditions only.

Regulation of biofilm formation by Pseudomonas chlororaphis in an in vitro system

Microbiology, 2015
The mutants of Pseudomonas chlororaphis 449 with completely or partially suppressed accumulation of N-acyl homoserine lactones exhibited the absence or a pronounced decrease of their capacity for stimulation of biofilm growth in the presence of azithromycin.

Rhizosphere bacteria Pseudomonas aureofaciens and Pseudomonas chlororaphis oxidizing naphthalene in the presence of arsenic

Applied Biochemistry and Microbiology, 2010
Rhizosphere strains of P. aureofaciens BS1393(pBS216, pKS1) and P. chlororaphis PCL1391(pBS216, pKS1), exhibiting the ability to stimulate the growth of plants and protect them from phytopathogens, have been obtained. In these strains, plasmid pBS216 ensures naphthalene degradation and plasmid pKS1 confers resistance to arsenic.

Nematicidal Activity of a Nonpathogenic Biocontrol Bacterium, Pseudomonas chlororaphis O6

Current Microbiology, 2010
Bacterial culture filtrates of an aggressive rhizobacterium, Pseudomonas chlororaphis O6, displayed strong nematicidal activity. The nematicidal activity of P. chlororaphis O6 was markedly reduced in the gacS mutant of P. chlororaphis O6 grown in the presence of glycine, but no reduction of nematicidal activity in the gacS mutant was noted in the ...

5-Cyanovaleramide production using immobilized pseudomonas chlororaphis B23

Bioorganic & Medicinal Chemistry, 1999
A biocatalytic process for the hydration of adiponitrile to 5-cyanovaleramide has been developed which can be run to higher conversion, produces more product per weight of catalyst, and generates significantly less waste products than alternate chemical processes.

Interaction of silver nanoparticles with an environmentally beneficial bacterium, Pseudomonas chlororaphis

Journal of Hazardous Materials, 2011
This study explores the potential antimicrobial mechanisms of commercial silver nanoparticles (Ag NPs) in the environmental bacterium, Pseudomonas chlororaphis O6. The 10nm size NPs aggregated in water, as demonstrated by atomic force microscopy. Solubility of the NPs at 10mg/L was 0.28 mg/L (pH 6) and 2.3mg/L (pH 7); release from 10mg/L bulk Ag was ...
