UV Light vs. Fungi: Can Ultraviolet Disinfection Stop Mold Growth?
writer: Released:2026-01-22 12:41:09 Click:

 During humid rainy seasons, in enclosed gyms, and in the corners of hospital wards… fungi are everywhere. Mold, athlete’s foot, and skin infections trouble countless people. Traditional disinfection methods such as chemical sprays and high-temperature sterilization either leave harmful residues or are unable to completely kill stubborn fungal spores. Ultraviolet light, this scientifically proven “invisible killer,” is becoming a revolutionary force in the field of fungal control with its characteristics of high efficiency, safety, and environmental friendliness.

The Scientific Basis for Ultraviolet Light Inactivating Fungi

 

As eukaryotes, fungal cell structures include cell walls, cell membranes, nuclei, and DNA/RNA. UV light (particularly the UVC band, wavelength 200–280 nm) can penetrate the cell wall and directly act on the DNA double-strand structure, forming pyrimidine dimers that lead to errors in genetic information replication, ultimately rendering fungi incapable of reproduction. Studies show that continuous UVC irradiation can inactivate 99.9% of common fungi, including drug-resistant species such as Candida albicans and Aspergillus, within seconds to minutes.

 

However, there are significant differences in fungal resistance:

Yeast: Thin cell walls, sensitive to ultraviolet light, can be inactivated by short exposure;

Filamentous fungi (e.g., molds): Complex structure requires higher intensity or longer exposure time;

Spores: Extremely high stress resistance requires professional equipment to ensure ultraviolet penetration.

 

Key conclusion: Ultraviolet light can inactivate fungi, but the effectiveness depends on wavelength, intensity, exposure time, and equipment design.

 

Lightbest The "Hidden Champion" in UV Disinfection Field

On the track of ultraviolet technology, Lightbest UV, with 13 years of technical expertise and as a national standard setter, has become an industry benchmark. Its products cover medical, industrial, and civilian applications, with "efficiency, safety, and intelligence" at their core, providing a one-stop solution for fungal prevention and control.

 

1. Medical-Grade Germicidal Defense: The Lifeline Blocking Cross-Contamination

Hospital wards, operating rooms, ICUs, and other areas are high-risk zones for fungal transmission. Lightbest's mobile UV sterilizing trolleys utilize UVC lamps with wavelengths of 253.7nm or 185nm to achieve highly efficient disinfection and germicidal action in application scenarios. Actual test data indicates that their products can eliminate 99.9% of airborne Candida albicans within 30 minutes, while avoiding direct human exposure to ultraviolet light, ensuring the safety of medical staff and patients.
