ABSTRACT
Introduction:
To explore the feasibility of pulsed ultraviolet (UV) light technology for low-temperature disinfection, a series of experiments were conducted.Methods:
Pulsed UV technology's effectiveness in disinfecting Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli on different carriers were studied under varying temperatures.Results:
Under different temperatures and constant radiation illumination (i.e., distance), the disinfection effect was correlated with irradiation time; among the three carriers, the disinfection effect of cloth sheets was the best, followed by stainless steel sheets, and corrugated paper sheet. The disinfection effect on Gram-negative bacteria Escherichia coli was better than that on Gram-positive bacteria Staphylococcus aureus overall.Discussion:
Temperature has a limited effect on pulsed UV disinfection. Irradiation times and carrier types are influencing factors.
