Ultraviolet light inactivation and photoreactivation in the mycobacteria.
The kinetics of inactivation of mycobacteria by ultraviolet light were investigated. Mycobacterium tuberculosis and M. marinum were shown to be capable of photo-reactivation.
متن کاملDisinfection of swine wastewater using chlorine, ultraviolet light and ozone.
Veterinary antibiotics are widely used at concentrated animal feeding operations (CAFOs) to prevent disease and promote growth of livestock. However, the majority of antibiotics are excreted from animals in urine, feces, and manure. Consequently, the lagoons used to store these wastes can act as reservoirs of antibiotics and antibiotic-resistant bacteria. There is currently no regulation or con...
متن کاملUltraviolet light inactivation and photoreactivation of AS-1 cyanophage in Anacystis nidulans.
Black light effected photorecovery of AS-1 cyanophage and wild-type cells. However, only partial photoreactivation of AS-1 was observed in a partially photoreactivable mutant of Anacystis nidulans.
متن کاملPhotoreactivation in Vitro of Ultraviolet Inactivated Hemophilus Influenzae Transforming Factor
Hemophilus influenzae-transforming DNA, which has been inactivated by ultra-violet radiation, is reactivated by visible light in the presence of a cell-free extract of Escherichia coli B. The time rate of reactivation is increased by increasing the E. coli extract concentration, the temperature, and the intensity of illumination. Only DNA containing an ultraviolet-damaged genetic marker exhibit...
متن کاملExperiments on photoreactivation of bacteriophages inactivated with ultraviolet radiation.
Kelner (1949), working with conidia of Streptomyces griseus, discovered that light belonging to the visible range is capable of reactivating biological material that has been rendered inactive by ultraviolet radiation (WJY). Shortly after Kelner's discovery was known, a similar phenomenon in bacteriophages (bacterial viruses) was observed by accident. Plates of nutrient agar containing UV-inact...
