Recently, it was proposed that stimulation of DNA repair may be a physiological role for production of light by bacterial cells. On the other hand, it was also proposed that...
A new assay for detection of mutagenic pollution of marine environments, based on the use of a series of genetically modified Vibrio harveyi strains, was developed recently. Here, we compared this assay with a commonly used Ames test, employing mutants of Salmonella enterica serovar Typhimurium. We found that survival of S. enterica serovar Typhimurium in artificial marine water and in different samples...
