2. It induces photoionization, damaging essential biomolecules.
3. Cell walls and membranes absorb UV-C, compromising structural integrity.
4. Broad-spectrum pathogen inactivation results from combined genetic and cellular damage.
5. The effectiveness of UV-C disinfection is enhanced when combined with other hygienic practices, ensuring comprehensive microbial control.
6. Proper surface preparation can also improve UV-C disinfection efficacy by reducing shadowing and surface contaminants.

Because of these mechanisms, UV-C can quickly neutralize bacteria, viruses, fungi, and protozoa. The process’s efficacy depends on factors like exposure time, distance, and surface characteristics. This multi-pronged attack explains UV-C’s powerful disinfectant capabilities.

Microbial DNA Disruption

When UV-C light interacts with microbial cells, it causes specific damage to their DNA that leads to inactivation. It primarily forms pyrimidine dimers, such as cyclobutane pyrimidine dimers (CPDs) and 6-4 photoproducts (6-4 PPs), which block DNA replication and transcription. This damage prevents microbes from reproducing, effectively killing or inactivating them. UV-C can also generate oxidative DNA damage indirectly through reactive oxygen species. The extent of damage depends on wavelength, with far-UVC (200–235 nm) being both effective and less harmful to humans. Some microbes have repair mechanisms, like photoreactivation and nucleotide excision repair, which can reverse up to 60% of damage, impacting disinfection efficacy. The severity of DNA disruption ultimately determines microbial viability after UV-C exposure. Additionally, understanding the juice cleansing process highlights how nutrient-rich ingredients can support overall health during detoxification.
