•Cells exposed to plasma are found to have distorted surfaces (cellular walls) •Mold is also thought to die out in the same mechanism as bacteria.1. TEST method• Bread mold (Neurospora crassa-wild type strain; ORS-SL6a) is set at 107 per ml • DI water (distilled water) and VM culture medium are sprayed with the same amount of mold • Compare the sterilization effect by culturing on an agar plate after exposure to plasma with different energy intensity2. Purpose• To see the effect of killing bread mold by plasma3. TEST result • In distilled water and VM culture solution, it was confirmed that the sterilization power increases as the energy of plasma increases.Ryu, Y. H., Uhm, H. S., Park, G. S., & Choi, E. H.

Experiment result *Use of Gas Plasma (DBD) - After plasma treatment, bacteria killed on the substrate are confirmedRead more1. Test method- The calculated concentration of Staphylococcus aureus and E. coli are cultured in a medium- DBD Plasma radiation on the medium seeded with bacteria- Confirmation of bacterial colony reduction value according to treatment time2. Purpose - Verification of sterilization potential 3. Experiment results- There is a difference in the killing time according to the strain, but the longer the treatment time, the higher the probability of killing the bacteria.Reference: Journal of Korean Society of Occupational and Environmental Hygiene, 2018: 28(1): 61-79Read more - -
