Alcaligenes aquatilis QD168 is a marine, aromatic hydrocarbon-degrading bacterium, isolated from an oil-polluted sediment of Quintero Bay, industrial-coastal zone that has been chronically impacted by diverse pollutants. The aims this study were to characterize the phylogenomic positions spp. and genetic determinants physiological response A. model environmental stressors (benzene, oxidizing agents, salt). Phylogenomic analyses, using 35 housekeeping genes, clustered with four other strains...
Aerobic metabolism generates reactive oxygen species that may cause critical harm to the cell. The aim of this study is characterization stress responses in model aromatic-degrading bacterium Paraburkholderia xenovorans LB400 oxidizing agents paraquat and H2O2.Antioxidant genes were identified by bioinformatic methods genome P. LB400, phylogeny its OxyR SoxR transcriptional regulators studied. Functionality from strain was assessed complementation with null mutant aeruginosa ΔsoxR,...
Abstract Background Bacterial aromatic degradation may cause oxidative stress. The long-chain flavodoxin FldX1 of Paraburkholderia xenovorans LB400 counteracts reactive oxygen species (ROS). aim this study was to evaluate the protective role in P. during 4-hydroxyphenylacetate (4-HPA) and 3-hydroxyphenylacetate (3-HPA). Methods functionality evaluated p2- fldX1 that overexpresses FldX1. effects on were studied measuring growth hydroxyphenylacetates, 4-HPA 3-HPA, ROS formation....
Flavodoxins are small electron transfer proteins containing flavin mononucleotide (FMN) as a prosthetic group, which play an important role during oxidative stress or iron limitation. The aims of this study were the identification and characterization flavodoxins in model aromatic-degrader Paraburkholderia xenovorans LB400 analyses their protective effects induced by paraquat H2O2. Two genes (BxeA0278 BxeB0391) encoding (hereafter referred to fldX for flavodoxin from P. xenovorans),...
