Consequences of redox-active phenazines on the physiology of the opportunistic pathogen Pseudomonas aeruginosa
Phenazines are redox-active small molecules produced by bacteria. Although phenazines have been studied extensively for their roles as toxins, how phenazines benefit producing organisms is still being uncovered. Pseudomonas aeruginosa is a phenazine-producing Gram-negative bacterium that inhabits …

The Evolutionary Diversity and Biological Function of Phenazine Metabolite Biosynthesis in Burkholderia SPP
… redox-active secondary metabolites called phenazines (Phz). In the model opportunistic pathogen <em>Pseudomonas aeruginosa</em>, phenazines strongly contribute to the competitiveness, formation of biofilms, and virulence in multiple models of infection. Similar depth of knowledge on the …

The Roles and Regulation of the Redundant Phenazine Biosynthetic Operons in Pseudomonas aeruginosa PA14
… to produce colorful, small molecules called phenazines. These redox-active compounds were originally thought of as mere secondary metabolites or virulence factors that allow P. aeruginosa to infect plant and animal hosts. However, recently we have gained an appreciation for their diverse …

NATURAL OR BIO-INSPIRED POLYPHENOLS IN THE SYNTHESIS OF POTENTIAL CHEMOTHERAPEUTIC AGENTS
… namely benzoxanthene lignans, their related phenazines and bisphenol neolignans; furthermore during the synthesis of magnolol-inspired neolignans, an unexpected dihydrobenzofuran neolignan was also obtained and characterized. The products have been studied in collaboration with others …

Aqueous reactions of ozone with primary aromatic amines
… benzidines, aminodiphenylamines, and phenazines. The N-substituted polyaromatic compounds (NPACs), azobenzenes, azoxybenzenes, and benzidines, were the products of interest because of their potential toxicity. When the reactions were conducted under experimental conditions …

Rhizosphere competence, antibiotic and siderophore biosynthesis in Pseudomonas chlororaphis: implications for the biological control of cotton seedling disease pathogens
… antifungal antibiotics, including one or more phenazines. A Tiff Image Analyzer (TIA) software program was developed that allowed assessment of wild-type (wt) L-850, and (ant) and (sid) mutant populations as a function of cotton root surface area (cm²) in the absence of soil irrigation. …

Anticancer and antibiotic leads from marine organis
… afforded 15 known antibiotics including two phenazines, six 2-alkyl-4-quinolones, and seven rhamnolipids. 2-Nonyl-4(1H)-quinolone and 2-(1-nonenyl)-4(1H)-quinolone displayed potent antimalarial activity, which was first reported here. Based on the metabolic profile of antibiotics from P. …

Towards a Fundamental Understanding of Aqueous Organic Redox Flow Batteries – A Study of Degradation, Aggregation, and Reactivity
… molecules, including quinones, viologens, phenazines, and alloxazines, have been investigated as potentially cheaper RFB active molecules. While a few molecules have shown good performance, most organic molecules considered for RFBs have lower energy density and generally experience …

Secondary ion mass spectrometry imaging of surface-bound microbial communities
As we move into the heart of the 21st century we are finally beginning to understand the extent of microbial influence over everyday life. Truth be told, we humans are but guests on a planet ruled by a largely unseen, and often undiscovered, microbial population. In order to understand how the …
