[Photoquenching of the bioluminescence of the genetically engineered Escherichia coli TG1 (pXen7) strain in the presence of photodithazine]. / Fotoindutsirovannoe podavlenie bioliuminestsentsii genno-inzhenernogo shtamma bakterii Escherichia coli TG1 (pXen7) v prisutstvii fotoditazina.

The photoquenching of the bioluminescence of the genetically engineered Escherichia coli TG1 (pXen7) strain was studied in the presence of the photosensitizer photodithazine, a glucosamine salt of chlorin e6. The photosensitized quenching of the bioluminescence was found to correlate with the colony-forming ability of the strain. The data obtained are discussed from the standpoint of using biosensor luminescent bacterial systems for the assessment of the efficiency of photosensitizers in antimicrobial photochemotherapy.
