Biocontrol by Phenazine-1-carboxamide-Producing Pseudomonas chlororaphis PCL1391 of Tomato Root Rot Caused by Fusarium oxysporum f. sp. radicis-lycopersici [PDF]

Molecular Plant-Microbe Interactions, 1998
Seventy bacterial isolates from the rhizosphere of tomato were screened for antagonistic activity against the tomato foot and root rot-causing fungal pathogen Fusarium oxysporum f. sp. radicis-lycopersici.

Enzymatic Degradation of Phenazines Can Generate Energy and Protect Sensitive Organisms from Toxicity [PDF]

mBio, 2015
Diverse bacteria, including several Pseudomonas species, produce a class of redox-active metabolites called phenazines that impact different cell types in nature and disease. Phenazines can affect microbial communities in both positive and negative ways,

Refinement of metabolite detection in cystic fibrosis sputum reveals heme correlates with lung function decline. [PDF]

PLoS ONE, 2019
The bacterial growth environment within cystic fibrosis (CF) sputum is complex, dynamic, and shaped by both host and microbial processes. Characterization of the chemical parameters within sputum that stimulate the in vivo growth of airway pathogens (e.g.

Heterologous production of rhamnolipids in Pseudomonas chlororaphis subsp chlororaphis ATCC 9446 based on the endogenous production of N‐acyl‐homoserine lactones

Microbial Biotechnology
Rhamnolipids (RL) are biosurfactants naturally produced by the opportunistic pathogen Pseudomonas aeruginosa. Currently, RL are commercialized for various applications and produced by Pseudomonas putida due to the health risks associated with their large‐

Unraveling the molecular mechanism of FgGcn5 inhibition by phenazine-1-carboxamide: combined in silico and in vitro studies.

Pest Management Science
BACKGROUND Fusarium head blight (FHB), mainly caused by Fusarium graminearum (F. graminearum), remains a devastating disease worldwide. The histone acetyltransferase Gcn5 plays a crucial role in epigenetic regulation.

Investigation of the mechanisms involved in the biocontrol activities of natural products from a marine soil bacterium against rice blast. [PDF]

Pest Manag Sci
This study identified a Pseudomonas aeruginosa strain R64 from mangrove soil with broad‐spectrum antimicrobial activity and demonstrated the biocontrol effects of primary bioactive compounds from R64 in rice blast suppression. Abstract BACKGROUND Rice blast, caused by Pyricularia oryzae, is a devastating fungal disease threatening global rice ...

<i>Pseudomonas aeruginosa</i> Biofilms in Cystic Fibrosis: Interactions, Methods, and Therapeutic Strategies. [PDF]

Biomed Res Int
This review explores the role of Pseudomonas aeruginosa biofilms in cystic fibrosis (CF) pathogenesis. Biofilms, the main bacterial lifestyle in CF lungs, are key in therapy failure, immune evasion, and chronic infection persistence. This review examines biofilm structure, emphasizing extracellular polymeric substances (Psl, Pel, alginate, eDNA) and ...

Investigations of the Flavin-Dependent Monooxygenase PhzO Involved in Phenazine Biosynthesis. [PDF]

Microb Biotechnol
In this work, we aimed to enhance the hydroxylase activity of PhzO by heterologous expression of the flavin reductase Fre in Pseudomonas chlororaphis. This strategy not only improved PhzO's catalytic efficiency but also unexpectedly led to the discovery of a novel dihydroxylated derivative, 3,4‐dihydroxy‐phenazine‐1‐carboxylic acid.
