Abstract:

A genomic library of the Pseudomonas putida strain GR12-2 was screened to identify both genus-universal and strain-specific 8-kilobase inserts. The genus-universal clone (pAM141), in combination with the restriction enzymes EcoRI, PstI, and PvuII, was used to generate unique restriction fragment length polymorphisms for 20 related plant growth promoting rhizobacteria and seven reference strains. Strain restriction fragment length polymorphism profiles based on the genus-universal clone pAM141 allow positive identification of individual pseudomonad strains. The strain-specific clone (pAM227) cl

Abstract:

Thirty-one bacteria that belonged to the genus Pseudomonas were isolated from cyanobacterial mat samples that were collected from various water bodies in Antarctica. All 31 isolates were psychrophilic; they could be divided into three groups, based on their protein profiles. Representative strains of each of the three groups, namely CMS 35T, CMS 38T and CMS 64T, were studied in detail. Based on 16S rRNA gene sequence analysis, it was established that the strains were related closely to the Pseudomonas fluorescens group. Phenotypic and chemotaxonomic characteristics further confirmed their affi

Abstract:

Biofilms are complex structures that are crucial during host–bacteria interaction and colonization. Bacteria within biofilms are surrounded by an extracellular matrix (ECM) typically composed of proteins, polysaccharides, lipids, and DNA. Pseudomonads contain a variety of ECM components, some of which have been extensively characterized. However, neither the ECM composition of plant-associated pseudomonads nor their phylogenetic distribution within the genus has been so thoroughly studied. In this work, we use in silico methods to describe the ECM composition of Pseudomonas fluorescens F113, a

A nitrogen-fixing bacterium, designated strain 6H33bT, was isolated from a compost pile in Japan.

The species of the genus Pseudomonas are an important part of the microbiota associated with plants. These species can be beneficial to the host plant by promoting its growth, and by protecting it against diseases, but they can also have a phytopathogenic effect. The genus Pseudomonas and especially the species P. aeruginosa is classified among the pathogenic species, that are multi-resistant to antibiotics due to the possession of a large number of antibiotic resistance genes (ARGs). Therefore, the risk of contamination of crops by these genes is real and likely to present a danger in terms o

Abstract:

A Gram-stain-negative, rod-shaped, non-motile, non-spore-forming bacterium, designated strain BY-1T, was isolated from a soil sample from the city of Qiqihar in Heilongjiang Province, PR China. Strain BY-1T grew optimally at pH 7.0 and 30–35 °C in the presence of 0.5 % (w/v) NaCl. Analysis of 16S rRNA gene sequences revealed that strain BY-1T fell within the radiation of the genus Pseudomonas , and showed highest 16S rRNA gene sequence similarities to Pseudomonas luteola IAM 13000T (99.5 %) and Pseudomonas duriflava HR2T (97.3 %); the levels of sequence similarity with respect to other recogni

Abstract:

Two unusual, Gram-negative, catalase- and oxidase-positive rods, designated C2T and C5, were isolated from compost samples. Comparative 16S rRNA gene sequencing studies demonstrated that both isolates were members of the genus Pseudomonas and belonged to the Pseudomonas aeruginosa group. Strain C2T was most closely related to Pseudomonas cuatrocienegasensis 1NT and Pseudomonas borbori R-20821T (97.9 and 97.8 % 16S rRNA gene sequence similarity, respectively). However, phylogenetic analysis based on rpoD gene sequences revealed that both isolates could be discriminated from members of the P. ae

Abstract:

Bacteria of the genus Pseudomonas are pathogens in both humans and animals. The most prevalent nosocomial pathogen is P. aeruginosa, particularly strains with elevated antibiotic resistance. In this study, a total of eighteen previously identified Pseudomonas species strains, were isolated from chicken. These strains were screened for biofilm formation and antibiotic resistance. In addition, we evaluated clove oil’s effectiveness against Pseudomonas isolates as an antibiofilm agent. The results showed that Pseudomonas species isolates were resistant to most antibiotics tested, particularly tho

Abstract:

As the current episode of Acute Oak Decline (AOD) continues to affect native British oak in the United Kingdom, ongoing isolations from symptomatic and healthy oak have yielded a large Pseudomonas species population. These strains could be divided into taxa representing three potential novel species. Recently, two of these taxa were described as novel Pseudomonas species in the Pseudomonas fluorescens lineage. Here, we demonstrate using a polyphasic approach that the third taxon represents another novel Pseudomonas species. The 16S rRNA gene sequencing assigned the strains to the Pseudomonas a

Abstract:

Many species of the genus Pseudomonas are known to be highly tolerant to solvents and other environmental stressors. Based on phylogenomic and comparative genomic analyses, several Pseudomonas species were recently transferred to a new genus named Halopseudomonas. Because of their unique enzymatic machinery, these strains are being discussed as novel biocatalysts in biotechnology. In order to test their growth parameters and stress tolerance, five Halopseudomonas strains were assessed regarding their tolerance toward different n-alkanols (1-butanol, 1-hexanol, 1-octanol, 1-decanol), as well as

Pseudomonas is a large and diverse genus broadly distributed in nature. Its species play relevant roles in the biology of earth and living beings. Because of its ubiquity, the number of new species is continuously increasing although its taxonomic organization remains quite difficult to unravel. Nowadays the use of genomics is routinely employed for the analysis of bacterial systematics. In this work, we aimed to investigate the classification of species of the genus Pseudomonas on the basis of the analyses of the type strains whose genomes are currently available.

Bacteria of the Pseudomonas genus, including the Pseudomonas gessardii subgroup, play an important role in the environmental microbial communities. Psychrotolerant isolates of P. gessardii can produce thermostable proteases and lipases. When contaminating refrigerated raw milk, these bacteria spoil it by producing enzymes resistant to pasteurization. One possible way to prevent spoilage of raw milk is to use Pseudomonas lytic phages specific to undesirable P. gessardii isolates. The first phage, Pseudomonas vB_PseuGesM_254, was isolated and characterized, which is active against several proteo
