The simple answer is yes, even more organisms. The research shows that 254nm ultraviolet light is effective for all food borne pathogens, natural microbiota, mold and yeast. Because the size and shape of microorganisms will affect their absorption of ultraviolet light, the time required to kill each species is also different. How does UV sterilize? Microwave ultraviolet water treatment equipment Also known as ultraviolet disinfection or ultraviolet germicidal radiation (UVGI), the working principle is to destroy some chemical bonds, disrupt the structure of DNA, RNA and protein, resulting in the inability of microorganisms to reproduce. When a microorganism cannot reproduce, it is considered dead because it cannot reproduce in the host body and is no longer infectious.

How long will it take for these disgusting things to reach the "death" state? Let's talk about the details of destruction. Since UV sterilization uses the energy of UV to destroy biological molecules, its effectiveness depends on the total energy applied, which is affected by the length of exposure time and the distance from the light source. For example, if you use an ultraviolet lamp and place it 1 inch above the E. coli culture dish, it only takes 1-2 minutes to sterilize. It may take 5-10 minutes to sterilize surgical instruments in a medium UV box. 30 minutes is generally recommended for disinfection of 8-foot high biosafety cabinets in the laboratory.
