A dibenzothiophene (DBT)-degrading bacterial strain able to utilize carbazole as the only source of nitrogen was identified as Gordonia sp.5.25.8 due to its 16S rRNA gene sequence and phenotypic characteristics and revealed that this strain is highly tolerant to DNA damage and also refractory to induced mutagenesis.
Genotoxic and mutagenic effects of guarana (Paullinia cupana) in prokaryotic organisms.
Several pathways of hydrogen peroxide action that damage the E. coli genome
The phenomena of lethal synergism between UV irradiation (254 nm) and H2O2, the cross-adaptive response between different classes of genotoxic agents and hydrogen peroxide, and the role of copper ions in the lethal response to H 2O2 under low-iron conditions are summarized.
Role of OGG1 and NTG2 in the repair of oxidative DNA damage and mutagenesis induced by hydrogen peroxide in Saccharomyces cerevisiae: relationships with transition metals iron and copper
The use of metal ion chelators dipyridyl and neocuproine allowed us to evaluate the participation of iron and copper ions in the production of lethal and mutagenic lesions during H2O2 treatment in different DNA repair‐deficient S. cerevisiae strains.
