How UV-C disinfection works

Micro-organisms are microscopically small. They are everywhere and have an extremely high metabolism. For example, in hot and humid weather the number of moulds and bacteria increases exponentially.

Furthermore, micro-organisms produce mucus substances that are deposited on surfaces and can contaminate food and cause microbial decay of the products.

The cell nucleus of micro-organisms contains thymine, a chemical element of the DNA / RNA. This element absorbs UV-C light at a specific wavelength of 253.7 nm and changes to such an extent (formation of thymine dimers) that the cell is no longer capable of multiplying and surviving.
