Effect of temperature on Pseudomonas fluorescens chemotaxis [PDF]

Journal of Bacteriology, 1980
The effects of temperature and attractants on chemotaxis in psychrotrophic Pseudomonas fluorescens were examined using the Adler capillary assay technique. Several organic acids, amino acids, and uronic acids were shown to be attractants, whereas glucose and its oxidation products, gluconate and 2-ketogluconate, elicited no detectable response ...

Diversity of the Microbiomes in the Larval and Adult Stages of the European Cherry Fruit Fly (Rhagoletis cerasi) and Identification of Potential Biocontrol Candidate Taxa

Entomologia Experimentalis et Applicata, EarlyView.
First comprehensive characterization of the R. cerasi microbiome is reported. Stage‐specific variations in microbial composition are documented. Multiple bacterial entomopathogen taxa are identified as potential biocontrol candidates for R. cerasi.

Secondary metabolites from Pseudomonas fluorescens and Microcystis aerugionosa : isolation, structure elucidation, and quantification [PDF]

, 2009
This study focused on two separate topics. First, potentially beneficial products from the bacterium Pseudomonas fluorescens were investigated and in the second, methods were developed for the detection of toxins produced by the blue-green alga ...

Polyesterase activity and thermostability of carboxylesterases from Thermoleophilum album YS‐3

The FEBS Journal, EarlyView.
Three novel α/β‐hydrolases from thermophilic bacterium Thermoleophilum album display carboxylesterase and polyesterase activity. These enzymes hydrolyse PET, PLA and PCL both at high and moderate temperatures. TA21 shows superior activity, efficiently converting MHET to terephthalic acid. Structural features underlying substrate binding highlight their

Pfm-like enzymes are a novel family of subclass b2 metallo-β-lactamases from Pseudomonas synxantha belonging to the Pseudomonas fluorescens complex

, 2020
A carbapenem-resistant Pseudomonas synxantha isolate recovered from chicken meat produced the novel carbapenemase PFM-1. That subclass B2 metallo-β- lactamase shared 71% amino acid identity with β-lactamase Sfh-1 from Serratia fonticola.

Ocular Infection by a Psychrophile: Pseudomonas fluorescens

Indian Journal of Medical Microbiology, 2019
Accurate identification of infectious pathogens is essential for appropriate management of ocular infections. Routine laboratory protocols typically support bacterial growth at 37°C. We report a case, wherein we serendipitously isolated Pseudomonas fluorescens - an organism that prefers lower temperatures for optimal growth (psychrophilic) in the ...

Gallium toxicity and adaptation in Pseudomonas fluorescens [PDF]

FEMS Microbiology Letters, 1992
When cultured in a defined citrate medium supplemented with 1 mM gallium (III) Pseudomonas fluorescens ATCC 13525 experienced a lag phase of 40 h with no apparent diminution in cellular yield. Following initial uptake of the metal-ligand complex, gallium was secreted in the spent fluid. This lag phase was abolished either by inoculating the medium with

Sea Lice (Lepeophtheirus salmonis) Harbour Putative Fish Pathogens: Insights From Illumina and Nanopore Sequencing

Journal of Fish Diseases, EarlyView.
ABSTRACT Ectoparasites that penetrate host skin can act as biological or mechanical vectors for pathogens and, in some cases, serve as reservoirs. Crustacean ectoparasites of fish are potential vectors of pathogens, which is especially relevant for obligate pathogens (e.g., Aeromonas salmonicida) with limited seawater survival. Sea lice (Lepeophtheirus

Prevalence and characterization of Pseudomonas fluorescens and Pseudomonas aeruginosa isolates from breast chicken meat

Open Veterinary Journal
Background: Although chicken meat is a major source of dietary protein globally, it is highly prone to microbial spoilage, especially under refrigeration, posing economic and public health risks. Psychrotrophic Pseudomonas spp., particularly Pseudomonas

Effect of Microbial Inoculants on Uptake of Nutrient Elements in Two Cultivars of Sunflower (Helianthus annuus L.) in Saline Soils

Notulae Scientia Biologicae, 2010
A greenhouse experiment was conducted in order to evaluate the interactive effects of microbial inoculants on uptake of nutrient elements (N, P, K, Ca, Mg, Na, Cl, Fe, Zn, Cu, Mn) in two cultivars of sunflower. The trials were carried out on saline (EC =
