Uv light kills bacteria.

Does uv light kill beneficial bacteria in a pond. Uv radiation disrupts the chemical bonds that hold the atoms of dna together in the microorganism. While they are similar each type of ray has a different wavelength and can penetrate surfaces to a certain extent. Uv light is a particularly good option for sanitation because it kills bacteria regardless of drug resistance and without toxic chemicals.

The benefits and risks. This reaction safely kills bacteria or viruses by a lighting strike and leaving a safe fresh and odor free environment without any residue or chemical smell.

Ultraviolet germicidal irradiation uvgi is a disinfection method that uses short wavelength ultraviolet ultraviolet c or uv c light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their dna leaving them unable to perform vital cellular functions. Uv a has the longest wavelength of 320 400 nm and is responsible for 95 of the uv radiation that reaches. Prolonged exposure to uv light helps ensure complete kill off of all microorganisms.
