The outer membrane of microbial cells forms an effective barrier for hydrophobic compounds, potentially causing an uptake limitation for hydrophobic substrates. Low bioconversion activities (1.9 U g(cdw)(-1)) have been observed for the ω-oxyfunctionalization of dodecanoic acid methyl ester by recombinant Escherichia coli containing the alkane monooxygenase AlkBGT of Pseudomonas putida GPo1. Usi...

A novel ice-nucleating bacterium (INB) was isolated from Ross Island, Antarctica. INBs could be isolated more frequently than was generally thought. INB strain IN-74 was found in the white colony group. Strain IN-74 was identified from its taxonomic characteristics as a novel INB, Pseudomonas antarctica IN-74. When strain IN-74 was cultured aerobically in a medium consisting of the ice-nucleati...

Insertion of lux genes, encoding for bioluminescence in naturally bioluminescent marine bacteria, into the genome of Pseudomonas fluorescens resulted in a bioluminescent strain of this terrestrial bacterium. The lux-marked bacterium was used to toxicity test the chlorobenzene series. By correlating chlorobenzenes 50% effective concentration (EC50) values against physiochemical parameters, the p...

When competing for space and resources, bacteria produce toxins known as bacteriocins to gain an advantage over competitors. Recent studies in the laboratory have confirmed theoretical predictions that bacteriocin production can determine coexistence, by eradicating sensitive competitors or driving the emergence of resistant genotypes. However, there is currently limited evidence that bacterioc...

Coevolution with bacteriophages is a major selective force shaping bacterial populations and communities. A variety of both environmental and genetic factors has been shown to influence the mode and tempo of bacteria-phage coevolution. Here, we test the effects that carriage of a large conjugative plasmid, pQBR103, had on antagonistic coevolution between the bacterium Pseudomonas fluorescens an...

Loper, J. E., Kobayashi, D. Y., and Paulsen, I. T. 2007. The genomic sequence of Pseudomonas fluorescens Pf-5: Insights into biological control. Phytopathology 97:233-238. The complete sequence of the 7.07 Mb genome of the biological control agent Pseudomonas fluorescens Pf-5 is now available, providing a new opportunity to advance knowledge of biological control through genomics. P. fluorescen...

From a pyoverdin-negative mutant of Pseudomonas fluorescens AF76 a new lipopeptidic siderophore (ornicorrugatin) could be isolated. It is structurally related to the siderophore of Pseudomonas corrugata differing in the replacement of one Dab unit by Orn.

Escherichia coli argE and argH gene products were detected in Pseudomonas fluorescens argH122 carrying the E. coli F110 plasmid.

The present experiment was conducted in the Department of Fruit Science, College Horticulture and Forestry, Pasighat, Arunachal Pradesh, during year 2021-2022. trial laid out using two factorial RBD replicated thrice. Assam lemon trees were pruned at 25% (P1), 50% (P2) from top apex soil drenching with Pseudomonas fluorescens @ 90g/plant (B1), Trichoderma (B2), Azotobacter 15g/plant (B3) a comb...
