Pseudomonas fluorescens Complex and Its Intrinsic, Adaptive, and Acquired Antimicrobial Resistance Mechanisms in Pristine and Human-Impacted Sites

Antibiotics, 2022
Pseudomonas spp. are ubiquitous microorganisms that exhibit intrinsic and acquired resistance to many antimicrobial agents. Pseudomonas aeruginosa is the most studied species of this genus due to its clinical importance.

A Cytochrome Peroxidase from Pseudomonas fluorescens

Nature, 1953
A CRUDE extract of Pseudomonas fluorescens was found to oxidize a reduced dye, 2,6-dichlorobenz-enoneindo-3′-chlorophenol. The activity in the crude extracts seemed similar to the ‘dye oxidase’ activity described by Smith and Stotz in plant tissues1. On partial purification, the ‘dye oxidase’ activity was always associated with a pigmented component ...

Pyrimidine biosynthetic pathway of Pseudomonas fluorescens [PDF]

Journal of General Microbiology, 1990
Pyrimidine biosynthesis in Pseudomonas fluorescens strain A126 was investigated. In this study, de novo pyrimidine biosynthetic pathway mutant strains were isolated using both conventional mutagenesis and transposon mutagenesis. The resulting mutant strains were deficient for either aspartate transcarbamoylase, dihydroorotase or orotate ...

A novel pathway producing dimethylsulphide in bacteria is widespread in soil environments [PDF]

, 2015
The volatile compound dimethylsulphide (DMS) is important in climate regulation, the sulphur cycle and signalling to higher organisms. Microbial catabolism of the marine osmolyte dimethylsulphoniopropionate (DMSP) is thought to be the major biological ...

Gut Bacteria Improve Depressive Symptoms by Degrading Cortisol into Androgen

Advanced Science, EarlyView.
Chronic stress is an important risk factor for stress‐related disorders such as depression. Stress hormone cortisol is essential for the pathogenesis of stress‐related disorders such as depression. Some gut microbiota degraded cortisol, and improve depressive symptoms.

Antibacterial Mechanism of Dellaglioa algida against Pseudomonas fluorescens and Pseudomonas fragi

Fermentation, 2022
Pseudomonas fluorescens (P. fluorescens) and Pseudomonas fragi (P. fragi), two kinds of psychrotrophic Pseudomonas species with pathogenicity, are likely to contaminate foods and cause diseases even in fairly cold environments, an outcome which should be

Massetolide A Biosynthesis inPseudomonas fluorescens [PDF]

Journal of Bacteriology, 2008
ABSTRACTMassetolide A is a cyclic lipopeptide (CLP) antibiotic produced by variousPseudomonasstrains from diverse environments. Cloning, sequencing, site-directed mutagenesis, and complementation showed that massetolide A biosynthesis inP. fluorescensSS101 is governed by three nonribosomal peptide synthetase (NRPS) genes, designatedmassA,massB ...

Nonribosomal peptides, key biocontrol components for Pseudomonas fluorescens In5, isolated from a Greenlandic suppressive soil. [PDF]

, 2015
UnlabelledPotatoes are cultivated in southwest Greenland without the use of pesticides and with limited crop rotation. Despite the fact that plant-pathogenic fungi are present, no severe-disease outbreaks have yet been observed.

A Natural Plasmid Uniquely Encodes Two Biosynthetic Pathways Creating a Potent Anti-MRSA Antibiotic [PDF]

, 2011
Background Understanding how complex antibiotics are synthesised by their producer bacteria is essential for creation of new families of bioactive compounds. Thiomarinols, produced by marine bacteria belonging to the genus Pseudoalteromonas, are hybrids
