1. A method for disinfecting air, contact surfaces, or materials by inactivating bacteria from one or more pathogenic Gram-positive bacterial species in the air, on the contact surfaces, or on the materials, said method comprising exposing the one or more pathogenic Gram-positive bacterial species to white light containing blue light without using a photosensitizer,
wherein the one or more pathogenic Gram-positive bacterial species comprise Enterococcus species,
wherein at least a portion of the blue light that inactivates the one or more Gram-positive bacterial species consists of wavelengths in the range of 400-500 nm, and
wherein the method is performed outside the human body, and the contact surfaces or the materials are non-living.
