Comparision of the Bactericidal Effect of the UV and Blue-Light Regions on Selected Escherichia Coli and Staphylococcus Aureus Strains
Some Bacteria are important microorganisms that threaten human health. Especially Escherichia coli and Staphylococcus aureus can cause serious diseases in humans. Antibiotics are used to stop these infections and prevent bacteria from multiplying. However, it has been observed that these antibiotics...

| description | Some Bacteria are important microorganisms that threaten human health. Especially Escherichia coli and Staphylococcus aureus can cause serious diseases in humans. Antibiotics are used to stop these infections and prevent bacteria from multiplying. However, it has been observed that these antibiotics have side effects as well as their benefits. Therefore, the resistance of these bacteria can be reduced with rays of different wavelengths. In our study, the effects of three types of light with wavelengths of 254 nm, 365 nm and 460 nm on Escherichia coli and Staphylococcus aureus bacteria were investigated. The reason we chose these rays is that two of them have short wavelengths and are harmful rays, while the other one is in the visible region and is harmless. While a significant decrease in the number of colonies was observed under the operating conditions of 254 nm and 365 nm wavelength lights falling in the UV region, no colonies were observed in the 460 nm wavelength light. In the second trial results, 44% growth was achieved at 365 nm and 56% growth was inhibited. S. aureus growth stopped completely at 460 nm. At 254 nm, 14% growth was achieved and 86% growth was inhibited. It was observed that there was 3% growth and 97% growth inhibition at 365 nm. As can be clearly seen from the results, no significant bacterial growth was observed at 460 nm. In our literature studies, it can be seen that no study has been done on this wavelength before. |
