Abstract

The authors provide a research study examining the airborne microbial killing efficiency of a unique photocatalytic reactor (PCR) to eliminate fungal and bacterial pathogens. The study examines baseline bacterial and fungal cultures, commonly known as pathogens, collected at specific clinical sites. The cultures were incubated, and separate culture counts (colony-formed units, or CFUs) for specific microbes were recorded for the given clinical area. The samples are identified by gram stain and special growth media and samples of unique clinical interest such as methicillin-resistant Staphylococcus aureus (MRSA) are studied in depth, identifying genus and species in varying culture media. Samples and cultures are collected at specific times for a 24-hour period after the installation and use of the PCR biocide unit, revealing up to a 300% reduction of airborne microbes.
