Genome diversity of Pseudomonas aeruginosa PAO1 laboratory strains.
Pseudomonas aeruginosa PAO1 is the most commonly used strain for research on this ubiquitous and metabolically versatile opportunistic pathogen. Strain PAO1, a derivative of the original Australian PAO isolate, has been distributed worldwide to laboratories and strain collections. Over decades discordant phenotypes of PAO1 sublines have emerged. Taking the existing PAO1-UW genome sequence (name...
متن کاملPseudomonas aeruginosa PAO1
Growth and conversion to the mucoid phenotype by nonmucoid Pseudomonas aeruginosa PAO1 was studied in a chemostat system under conditions designed to reflect those likely to be present during chronic infection in the lung in cystic fibrosis patients. Mucoid variants were consistently isolated during continuous culture in the presence of 0.3 M NaCl or 5 or 10% glycerol. Mucoid subpopulations wer...
متن کاملDraft Genome Sequences of Two Alginate-Overproducing Variants of Pseudomonas aeruginosa, PAO1-VE2 and PAO1-VE13
The small envelope protein MucE and the sensor kinase KinB are a positive and negative alginate regulator, respectively. Here, we announce the draft genome sequences of the alginate-overproducing variants Pseudomonas aeruginosa PAO1-VE2 (PAO1 with constitutive expression of mucE) and PAO1-VE13 (PAO1 with kinB inactivated). Both mutants were generated from a transposon mutagenesis screen.
متن کاملDetection of Neuraminidase Activity in Pseudomonas aeruginosa PAO1
Objective(s) Some properties of neuraminidase produced by Pseudomonas aeruginosa PAO1 growth in a defined medium (BHI) were examined and evaluated for its features. Materials and Methods The obtained supernatant enzyme of P. aeruginosa PAO1 cultures was used in a sensitive fluorometric assay by using 2'-(4-methylumbelliferyl) a-D-N acetylneuraminic acid as substrate. As hydrolyzing MUN with ...
