Abstract:
:Strains of the filamentous gliding bacterium Vitreoscilla, LB13 and C1, are shown to be highly sensitive to UV-A (320-400 nm), with an LD50 of less than 20 kJ m(-2). Vitreoscilla LB13 can be protected from UV-A by including superoxide dismutase and catalase, separately or in combination, during the exposure, indicating an involvement of reactive oxygen species. LB13A, a photo-insensitive strain derived from LB13, is described.
